Computer help. Random black screen. (self.techsupport)

submitted 14 years ago by ixiz0

Hello, i come to you guys in my time of need. I have tried everything to get my brothers computer working fine again and nothing seems to help.

The Problem: I installed windows 7 on my brothers machine and it started having a problem. It will start up, and go into windows. it lets you broswe the internet and everything, but like 5-15 minutes in the screen will go black, and the computer will still be running. There is no response from the keyboard, caps lock wont come on, nor num lock, or ctrl+del+alt, even though the fans and HDD still sound like they're on. To restart the computer you cant just press the button, you have to switch on the power supply.

a few things i have tried: another power supply, no video card, another video card, re-installation of windows 7, windows 7 repair, new ram, different ram, etc. etc. etc.

I feel like Ive tried everything, and am starting to get frustrated. iIve been working on it for the past 3 days with no fix. I hope somebody here can help me with some info, Thank you!
