Why do I get a black screen on my computer after a while?

A black screen on your computer can mean several things. A black screen is most commonly a screen saver, but there are also much worse possibilities.

//

My computer switches to a black screen after about 5 to 15 minutes of use. Then I have to turn it off to get another 5 to 15 minutes of use. Maybe someone could just post what part of my computer is causing this black out.

This is another of those questions that I get very, very regularly. Unfortunately it’s hard for me to offer concrete help. The problem is that there are so many possibilities, and there’s no single “part of my computer” to point at. There are many things to look at, and look for.

It’s probably obvious to you already, but I’ll say it anyway, it could just be a screen saver. If you wiggle the mouse or hit a key on the keyboard and your screen comes back, that’s it. You can adjust the screen saver behavior in the Display portion of Control Panel.

If you have a laptop, it’s possible that the computer has gone into standby or hibernate. If you simply push the power button and it comes back up to where you were (possibly after a few seconds), that’s probably it. Normally a computer should only go into standby if you’re not actively using it, but if your battery is very low, it my force standby in order to avoid losing what you’re doing.

Those are both normal, and expected behaviors. What’s left is typically an indication of a problem. In my best guess “order of likelihood”:

It could be your computer. The most common abnormal reason for a black screen is probably a computer crash. Given that it’s consistently 5 to 15 minutes after boot up, I’d be looking at possible overheating, or perhaps a power supply that’s going out. One simple way to determine if it’s just the monitor going out or the computer crashing is to play some audio on your computer. Perhaps load up a longish mp3 play list, for example. If the monitor goes black, but the music continues to play, you know that the computer is running, and that the problem is either the video card, video drivers, the monitor or the cables in between.

The most common abnormal reason for a black screen is probably a computer crash.

It could be a virus, or your computer’s other software or drivers. Unfortunately bad drivers for any hardware on your system can cause the machine to crash or go to a black screen without warning. I’ve also heard of this as a symptom of a virus (though typically a poorly written one). It’s more common that you’ll actually get a message, or the dreaded “blue screen of death”, but nonetheless, it’s still possible that bad software, particularly hardware drivers, could cause it. As always, make sure your computer is up to date on Windows, and of course anti-spyware and anti-virus software as well.

It could be your video drivers. Even though I’ve already mentioned drivers in general, the video drivers are worth a closer look. The software used to control the video card, which can often be quite complex, can also fail, have a bug, or crash in such a way that the screen goes black. Most commonly this’ll crash the computer with some kind of visible message as above, but it’s also possible that the video card drivers or software could fail, and the computer keep running. Certainly making sure you have the latest drivers always makes sense.

It could be the video card in your PC. It could, for example, be overheating, and as a result cut out after 5 to 15 minutes. Turn it off, it cools down, and you get another 5 to 15 minutes of use.

It could be your monitor or display. Monitors and LCD displays can break, and one way they can break is to go completely black. And yes, sometimes they’ll even come back on for a while, though it’s typically not as consistent as you’ve outlined in this particular question. The best way to test this, of course, is to try a different monitor for a while.

It could be your CRT’s circuitry. Many CRT monitors often have their own standby circuit – if they notice that the signal has gone, they also power-down. If that standby logic fails, they could possibly go into their own standby state improperly. Usually there’s a standby switch that, if you push it, causes the monitor to spring back to life.

It could be cable between your monitor and computer. Again, this typically isn’t as consistent with respect to time as you describe, but a failing monitor cable can definitely cause an intermittent display, or cause it to go to black.

So as you can see, it’s not a simple process to diagnose. Some steps, like trying another monitor or cable, are pretty easy for you to take yourself. But if you’re not comfortable diagnosing system crashes or hardware problems like potential overheating, it might be time to take the computer in to a local technician for a hands-on diagnosis.

    I had this same issue with my old computer that was running Win 98 SE. I went through and systematically started to replace everything in there. By the time I was done, I only had the CRW drive, motherboard and ram that was original over the computer.

    Still was giving me the issues.

    It took an upgrade to Win XP to stop the problems, and I haven’t had a problem since. I hope that this helps anyone else.

    I’ve had this problem with an USB mouse. It seemed like Windows “didn’t know that I was using the mouse” and went into screensaver mode.
    After hitting a key on the keyboard, the screensaver went away and I was able to continue using the system.

    A really strange problem indeed. However, replacing the mouse solved the problem.

    The screen of my laptop suddenly gets often black as well, and when that starts I can switch off/on forever but it keeps doing it after a short while. It’s just the screen, the computer keeps working. I remedied this by disabling the screen saver and disable any hibernation or stand-by.

    I think I have solved the “black screen” problem, and I know virtually nothing about computers. After I bought my HP f1503 monitor with HP computer about 3 years ago, I began having problems from the beginning. After about 15 days spending in excess of 15 hours on the phone with MSN technical support in Nova Scotia (and after spending 35 bucks for technical support), a very smart person discovered that my Norton anti-virus software that had been installed at the retail store where I purchased the computer had basically attacked my computer, placing a firewall between me and the internet, preventing me from accessing the internet. After that problem was corrected, and after downloading Semantic (phonetic) software as well, I began noticing the black screen syndrome. I do not believe for one instant that my relatively new computer monitor is defective; rather, I firmly believe that Semantec and/or Norton anti-virus personal firewalls are the true culprits. I basically removed the programs from my hard drive and the problem has corrected itself. I also believe that all Norton/Semantic products place a fire wall inside the PC and cause such problems. It reminds me of a certain Star Trek episode (original series) where the computer attacked everything (NOMAD, or something like that); perhaps Norton should rename itself NOMAD….

    Although, like Leo said, this can be caused by a miriad of things, I had this same problem happen to me a few weeks ago, so I figured I’d share. I had two seperate Dell Optiplex GX270’s at my office that, within a week of each other, would randomly show a black screen. The power light on the PC would remain solidly lit, but everything else would become unresponsive as if the machine was off.

    I opened up the case (after completely reinstalling the operating system all all apps) and saw the problem. On both machines, several of the capacitors had blown out; in one of the machines they had visibly leaked. The capacitors are the tall, tubular shaped things that stick up off of the board (there are good pictures of damaged ones here http://en.wikipedia.org/wiki/Capacitor_plague)
    Repairing this requires either a supply of the correct type of capacitors, a steady hand, and a soldering iron, or, as in my case, a long and annoying call to Dell support to get a replacement motherboard.
    An initial visual inspection of all installed hardware (add on devices, like video cards, frequently have capacitors as well) would have saved me a lot of time, and is another point to add onto your troubleshooting list.

    Cheers!

    My friends PC starts to Boot up, goes through POST and the Windows Logo appears, then the Screen changes and gives various options of starting Windows, the keyboard does not respond and after the 30 seconds tries to boot but the monitor goes into standby mode and nothing can be seen on the screen, after pressing the Reset button, the Windows Screen appears again and the System keeps Restarting by itself with nothing on the Screen, it is not possible then to go into the BIOS to see what is happening or to change or load Default settings

    I too am experiencing regular periodic black screens. The power light on the lcd monitor stays on. If I turn it off and then on again after 3 or so seconds the monitor comes back to life. Other programs seem to be working okay, including audio…I noticed that when my son is logged on under his own XP userid, the problem disappears. I am beginning to suspect a virus. If so – What virus would be causing this and how do I get rid of it? I run Mcafee regularly….

    I get the black screen after my computer has been idle for a while and the screensaver has already come on. Usually, I have to turn it off and reboot. I recently reformatted the system but it doesn’t seem to be linked to that. Could it be the fan?

    I was running Photoshop CS2, designing a signature for myself, right in the middle of doing my work, the computer crashed unexpectedly, hearing the eerie sound of death. 10 minutes later, when I was loading a screen in EverQuest, it crashed again. Then, I tried to check for spyware with Spybot, it didn’t get through, because it crashed again. I don’t know what’s causing this? I may have been to a few bad sites (porn sites), or download more then 100 songs on my computer But is that really the cause of the computer crash?

    I am a IT Specialist with IHS/DHHS and I have replaced over 180 motherboards with the bloating or leaky capacitors. Model(s) in question are the Dell GX270 Optiplex (all form factors) and less on the GX 280’s. Symptoms were like the computer went into hibernating/powersave, you would have to restart; some would restart repeatedly; some would go black screen twice a day or once every two or three days. All would go to black screen. It was very frustrating troubleshooting each one until Dell admitted to a capacitor problem on mainboards manufactered before a certain date.

    My screen was turning black after the computer had been working for a while , sometimes by clicking a link ,sometimes by itself.I increased the RAM of my computer from 512 MB to 768 by changing one of my 256 MB memory card to 512 MB memory card,since then I have not experienced any black screen and I use the advantage of having more memory as well.

    norton antivirus was causing black screen & not letting me to restoe my computer to the earlier date:After I uninstalled my norton antivirus by going to symantec (noton) website and using their removal tools (I could not remove it by using add or remove) was able to restore my computer to the earlier date immediately and it has been one month I haven,t had any black screen. so,either norton boosts the existing problem of the computer or causing the blackscreen by its own interaction.you can try it if your computer is using norton. Increasing,ram did not help very long ,but I think one month of normal screen would be enough to judge my attempt.

    Hi.On my 2004 XP Packardbell,I am getting the oppoite of the above problem. Instead of getting a Black screen after 5to15 mins afgter boot,mine starts as soon as ithas fully booted.I have put up with it for around 2months but it seems to be getting very gradually worse.It goes Black on all but a small handful of movements and clickings of the mouse.Their is also a horizontal flickering associated with this problem.After a while,however, itsometimes improves but is generally unpredictable. I did once notice an improvement after using checkdisk and recovery of bad cluster utility and defragmenting. However it advised me to defrag ontwo occasions only a month apart so I have been ignoring this having been told that over defragging can seriously harm the hard drive.

    i have done all of these things, at first i thought i was my mouse and keyboard so i switched out, still didnt work. i plugged monitor back(switched from Nvidia Geforce 8500gt to motherboard) into the standard lot on the panel and nothing. the only time this happens is when its been sitting for about ten minutes ( the time my screensaver is supposed to come up after) and goes black. nothing short of turning off the computer will get the screen back up. with it not being GFX card and having tested for viruses and switching out equipment nothing has improved. then i thought could it be the motherboard malfunctioning? i already have a USB port that doesn’t work so it does make sense.. ideas? comments?

    I had my Toshiba Satellite Turion 64 for several months. Not long after purchasing, my monitor would go black requiring reboot to function. I took the advice in this post and played a CD leaving it to continuously rotate play. Eventually, the screen went black and the CD no was no longer playing either. I guess this means my computer completely stopped working. What does this mean? I did purchase extended warranted which requires me to mail my laptop back to the manufacturer. At this point, it looks like that may be my only alternative.

    Thanks to the commenter Chris. I also have a Dell Optiplex GX270 that randomly “turns off”, but still shows good power. Inspected the motherboard, and I can see two caps with leaking electrolyte on the top of the cap. Dell’s out of stock, so I have a rather hefty boat anchor. The Dell folks did try to sell me several other items – none of which would actually replace the motherboard.

    This is actually for my friend who has xp operating system and in recent time has been getting a black screen, he has checked all the connections, they are fine, has also blown the computer out so that it is clean, now he gets black screen sometimes as early as 7 – 10 minutes after start up, it lasts approx 1/2 hour and then can see the desk top again, these episodes are becoming more frequent, could it be the power supply on the way out? The video card….or time to buy an new computer….he was thinking of reformatting the hard drive but not sure that this would help if the problem does lie in the power supply or video card…if we are in an im and the mouse is in the right place he can still send me messages, however with the black screen he cannot read the response..any help would be appreciated.

    I wouldn’t expect reformatting to help – this feels like a hardware issue. My first step would be to try a different monitor for a while – it actually kinda feels like the monitor might be dying.

    I have a Toshiba Tecra A6. When my computer crashes, the backlight to the LCD screen shuts off and a buzzing sound comes out of the speakers. Strangely this only occurs when viewing videos through Windows Media Player or when viewing youtube videos. I updated my flash player and WMP, but I still get this problem. It’s been occuring for probably 2 or 3 months now and I’ve had this laptop since March or April of 2006. The only tinkering I’ve done is undervolting all multipliers to the CPU. I restored the voltages to default for a bit to see if that would solve the problem but unfortunately it hasn’t. I’ve tried different ATI drivers. I’m sure it’s not overheating, well considering the CPU anyways, as RMclock registers temps in the mid 40’s. If it means anything, I can watch movies/clips through VLC player flawlessly and I do so several times a week. I’ve updated as many drivers as I could. I’ve had someone from dslreports.com check my Hijackthis logs and other logs back last October as I got a virus from accepting to update my JAVA from an internet explorer popup (silly). Any help would be appreciated.

    Hi!

    I have gone through the same problem (on multiple games including SC2, MW2, ArmaII, etc) and i believe i am familiar with it.

    Qosmio crashing during games (even freecell) with a black screen and loopy sound from the speakers. Solved only with a hard reset. Problem does not happen if you are running off the battery.

    I believe i might have a solution. I have seen the problem crop up across the board on all Qosmio laptops (including my own X300) and i eventually did quite a lot of research and found out a solution.

    The problem really pertains to fixing the clock frequencies between the GPU and the CPU and that caused all the problems. They apparently loose sync with each other at variable speeds due to a bug in the power management.

    The detailed explanation and solution are on http://www.fixmyqosmio.com and you can check out the writeup there.

    It worked for me and it has worked for over 100 other people who have liked it and used it. !!Warning!! it is a COMMERCIAL solution (although it has a 100% refund guarantee) so dont go to the site unless you want to.

    I am not soliciting for business. just letting you know that there IS a way to solve the problem and Toshiba are either not concerned or unable to solve the problem. Please dont make the mistake that i made (taking my out of warranty laptop to toshiba) and paying for servicing it.

    The service center cant help as it just DOES NOT KNOW how to solve the problem. They service it and hope for the best.

    Hope that was some help

    I was having the same problem that i read here and could not solve that for a very long time.

    I have a qosmio from Toshiba and i always used to give me the black screen of death and i was really frustrated.

    I read in the comments from a guy called LordNOD that there is a website called http://www.fixmyqosmio.com

    It has a solution and i tried it (yes i risked sending 15 bucks to the guy) And it worked! Saved me a bundle of money! Toshibas asked for $1200 to fix it and he did it in 15. Totally worth it

    Do test it out as i was glad i did (an no no one paid me or asked me to do this! I thought i should share my good fortune with others and prevent people from wasting hard earned cash in these hard times)

    Hey i was wondering how do i get to display portion of my control panel? i searched it in there
    but it said no results?

    Depends on your version of Windows. Don’t use search, open control panel directly and browse through the available entries.

    I think i have a answer to this the problem in my case was cracking of the windows code after installation/ formatting with windows 7.My Hardware guy came with his hard disk attached the hard disk to my USB port and simply put the code in the control panel and restarted the laptop twice. it was done in minutes. and i was rid of three problems error message when starting for genuine windows software, build 7000 error message in the right bottom corner and black screen. please think twice before formatting or viral attacks.

    My computer started going to black screen after Time/Warner advised they were giving Roadrunner customers 40% more speed free and all I had to do was disconnect power to the modem for 30 seconds. I don’t know if this was just a coincidence that it happened at this time or if it was connected to adding the speed. When the screen goes black on my PC, it will come back up fine when I turn off and back on. It doesn’t seem to go black until I have left it on idle for some time. It appears everyone here is talking about laptops. Would the solutions be the same for a PC? Thanks.

    My pc just started doing this today…However, it is fine as long as I am just on internet explorer, etc…When I play my games online, that is when (after roughly half an hour of play) the screen goes black, though the computer is still running. The entire computer is brand new, minus the 2 slave drives which are from my old computer. The motherboard, video cards, heat sinc, etc…are all new. Is it time to replace the monitor? (again, working fine as long as I don’t bring the games up)

    Leo’s general comment that “there are many possibilities” is very true! I will tell share my findings re: laptops. I have had several on my test bench that exibited the same black screen symptom. The first was my daughters Acer. I found the processor cooling duct PACKED with lint. Since that fix (cleaned the duct) the unit has been working another 2 years. This problem was found on others. No surprise, as they spend much time on someone’s lap sucking in lint. I recommend a cooler but settle for a small board large enough for the computer and mouse, if used. A secondary benefit is a cooler lap!
    The second problem seen was the Heat Pipe contact on the processor. It was on a less than 1 year old Acer. The contact area was NOT Cleaned in original factory assembly. It required a new mb, cleaning the heat pipe contact and Artic Silver compound.
    HEAT IS THE NEMISIS OF ALL COMPUTERS which includes desktops!

      This sounds like a hardware problem with the display itself. You’ll need to have a technician look at it.

    what can it cause the display of my hp laptop not to work and the keyboard is working.

    I have two monitors and this has been happening. I was considering a faulty wire or something of that sort but I doubt it would happen to both monitors at the same time
