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

//
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. Can you tell me what part of my computer is causing this black out?

I get questions that boil down to this symptom quite often.

Unfortunately, it’s very hard for me to offer concrete help.

The problem is that there are so many possibilities that could lead to this symptom. There’s simply no single “part of my computer” to point at.

There are many things to look at, and look for, so I’ll review the most common causes and remedies.

My computer doesn’t work, what do I do?

//
My son has a computer that is not working. It only has a blank screen. Also the light to the hard drive it not on. Is the hard drive broken? Can I get the computer repaired. Or do I need to buy another one?

I get so many variations on this question so often that I just have to address it.

In short: there’s nothing even close to enough information for me to hazard a guess as to what might be wrong. And it’s just not a simple yes or no question.

Let me run through a list of some of the things it might be.

Why Does My Screen Go Black After the Windows Screen When I Boot?

//

My system will only boot correctly if I enable VGA mode. On a regular boot the OEM logo comes up, then the Windows logo, but after that I only get a black screen.

Windows tries to set the display to its configured settings right after displaying the Windows logo, and just before displaying the login screen or desktop.

Nine times out of ten if that’s when your display stops, it’s simply because your display settings are set to something that your monitor can’t handle. Depending on what it’s not supporting, some monitors respond by going black … others just go “crazy” displaying unintelligible gibberish.

If that’s the problem, it’s fairly easy to fix.
