Built a new PC

[LordChristof]

I have no idea whats wrong with it right now. Its been running fine for about a week, but now its doing something weird. While playing video games. It shuts down, but the Case LED's are still running and the moniter goes black then the moniter comes back on when it says "press f11 or del blah blah". Any way what could this be? It doesnt seem to be overheating. The cpu was at 40 degrees Celsius while playing Planetside. The GPU is fine as well. What could this be?

What are your system specs?

System specs?

Would need specs, to clarify.

You say GPU is fine - how do you know?

A first shot (in the dark) would be the PSU, since unstable voltage or overdraw can cause black screens. Could be an unstable overclock. Or faulty GPU... There's too many variables - can you elaborate on what you are doing, when that happens. And how often. And which specs you have.

first and easiest thing to check would be the ram, re seat it and try again, if it doesn't work try different ram slots on your board, if that doesn't work take out 1 stick at a time and test.

basically it's the easiest thing to check when anything is a miss and often the source of random crashes while doing I tensile things.

Give this a go, or boot up, and individually stress each component one at a time, CPU, RAM, GPU and run them for a good while, see if anything makes it restart.

 

What's the specs and have you OC'd anything?
