Computer monitor goes black and computer freezes but sound still plays for around 5 to 10secs..and i have to hold the power button to turn pc off... i have redone drivers reinstalled windows etc.
not sure what it could be. psu? video card? MB.. if i go to play games it will do it every time..it will takes 5 to 15 mins.. even does this watching video at times.. all my temps are below 50s

its a dell so im sure thats why lol
but its a stock dell xps 9100..... i7 930' 8gb ram .. 525 watt psu ati 5670 1gb

Look how much tasks are running in system. Shut down task what you do not need to run. Look this. http://www.youtube.com/watch?v=KqpX_rb5VNk

Just google how to make my pc or windows faster.

Then try to run some bechmarks (video card) or wholesystem like Passmark. This isuue can video card related. Then just buy newone.
I think good card is GTX650Ti boost or better GTX 760 , 7950 or something like that. Maybe cheaper cards are good if you do not play new games.Then like 7750

i dont have much stuff running at all... i have redone windows and it still happens..
so maybe its the video card going bad?? it seems like it freezes more when im playing a game 100% like of the time.. and sometimes when a video utbe/twitch playing.. but always when i play a game.. but my temps seems to be fine.. so maybe video card?

or maybe its the psu?? it cant take the load so it does that?? im really not sure

or the motherboard going bad??

Try to run passmark first.
Then load if you do not have some temperature monitor for gpu andcpu.
Then look how much is when monotorr goes black.

You can remove thermal paste under cpu coolerand put in some new.
To gpu you can do this too. Or buy just new one

Then post results like this

Whole test of passmark. And after you removed thermalpaste and did put new it started to crash? Maybe too much paste?

Can it be a driver issue? You have OC'd that card?

Can you run 3D marks? Remove DVD cable first
Try this. remove dvd cableand play a game. If this works good.
If not maybe it is broken card. Hopeyou find good cheap card
7870 is good buy if find cheap used one (working one)

i just cant understand why screen cuts off and pc locks up but i can hear sound for like 5 secs after.. thats even watching a video while temps on the gpu and cpu are low

but while gaming it does it 100% of the time. it can take up to 5 to 15 mins for it to happen./

Hard to tell you what to do.
This you can try http://www.youtube.com/watch?v=Pl20SdLhuhM

My best quess is that it is video card problem.

Can be psu or mobo. Or anything..
Can video cable.. If you have other try that.
What brand and modell are your parts?
