Basically my pc is constantly shutting itself off, its quite..weird and frustrating tbh.

Before i had the following spec

Q6600
Asus P5NE-SLI
8800 GTS 640mb
2gb Geil 6400 ram

then i upgraded to 4gb, and it seems since then my pc shuts itself down everytime it does anything that requires effort such as loading a program, installing, playing a game (it shut itself down everytime i reach a certain point on the crysis demo, just off the beach for an example). It boots fine and this is what makes me wonder, i've tried the sticks in other combinations and ive also reverted back to 2gb, trying them in numerous slots and it seems to have no effect and i'm not even sure if it's the ram thats causing the problem in the first place. I vaguely remember having a similar experience with my previous pc but can't remember how i got around it.

Any help would be greatly appreciated it's a bit urgent that i get this pc running (need it for some 3d work and i'd rather use it to render then my lappy which will take twice as long).
 
how many sticks of ram do you have?
take one out try and play crysis, see how far you get.
if problem still there try the other stick and play again

this could tell you which stick it may be.
 
really don't know if it's the memory now as i just did a little experiment on a hunch.

Pc booted fine with two sticksof RAM in, i went to the bios screen, watching the CPU temp go from about 38degrees and slowly rise to 70 at which point the pc shut down, just wonderin as to how it got such a high temperature when it was just standing around in the bios, no real strain on the system at alll. :S
 
Did you build the PC yourself?
I'd check that the heatsink is fitted properly and replace the thermal compund.
If it's getting to 70'C in BIOS then it will certainly be overheating and causing the crash when under load during games.
 
I was about to suggest to look at temps, as stated above, check the seating of the heatsink and make sure it's on properly, you could also re-apply the thermal compound if you have any...And of course check that the cpu fan is spinning.

Out of interest...What cooler are you using?
 
Just an update, spent the morning taking off the cpu heatsink/fan and gave them a good clean lol. Seems to have done the trick as there doesn't seem to be anymore problems (touch wood).

I'm using the stock cooler that came with the Q6600.
