Having problems with your Dell Dimension 5100 (D51L1) PC Desktop ?

Screen goes black after 30 mins of working.

\015 Hi. I have a Dell Dimension 5100 (4 years old). After switching it on, it works fine for 30 to 45 minutes, then the screen goes black. There is still power to the screen and the computer. If I then switch it off and leave it for 10 to 15 minutes, it will switch back on but then the screen goes black again after a similar time. It looks like something is overheating and failing. Any ideas? Thanks in advance. Roy.\015

Answers :

There are a few things you need to check here.
1. It could be that your computer power management is set to turn your monitor and harddrive off after 30 to 45 min.

If the computer is however working for 30 to 45 min while you doing stuff and it shuts off, the there is an internal problem "Hardware"

I would suggest you check to see if the power management is set to turn off monitor 30 min and harddrive after 45 min. IF that is not so, then we go on to the next test.

It could possibly be your processor fan is not working so once your processor gets over heated it shuts off the computer.

Turn off the computer, remove the case "this is only if you know what you are doing" with the case off, power on the computer and see if the processor fan is working.

You can get back to me and I can walk you through it.

Hope thiss help.

My screen in my dell 1525 laptop died. I bought another one from dell. After installation the screen seemed to work great. After 4 or 5 min the screen goes blank. I use vista home.
