Can anyone solve my black screen problem?

[kingnothing83]

I bought a msi p965 motherboard but it died on me twice, I also got a replacement psu because that was found to be faulty (which maybe killed the msi motherboard both times). Anyway I started again with a new psu and the asus p5n-e.

Installed the mobo with new psu and everything seemed fine. Except about 1 week after the install i was watching a movie and the screen went black, sound was still playing but i had to restart, windows said id had a serious error. This problem seems to happen randomly even when just browsing the internet. It even happened when I was reinstalling windows.

I have bios 0401 installed but i still seem to have the problem. All the settings on the BIOS are on default except for primary graphics adapter which i have set as PCI-E (it was set to PCI). I just bought cheap memory so dont know what settings I should have.

Any idea whats causing it? Could the old psu that failed have damaged the graphics card, so is this a graphics card problem? Could it be a CPU, RAM or motherboard problem? Or even the psu again? Someone suggested overheating but I think thats unlikely because nothing is overclocked and the problem sometimes happens after the PC has been on 5 mins and sometimes 24 hours.

If anyone could suggest any BIOS settings which i should change, or thinks they know what the problem is I would be very grateful. I bought this pc 3 months ago and it still doesnt work so im very upset

Thank you all

I would suspect a bad video card.. but that is just a guess. Do have another one available that you could try?

No unfortunately not. It makes sense for you to be right as im getting the same problem on two different systems. I have heard of incompatibility with some asus boards and my psu though so i guess thats a possiblity. i wish i had another graphics card that i could try rather than RMA'ing the card on the off chance
