PC turns off while playing

[RaEm26]

Please Help

Have a year old Palit 8800GT Sonic and when playing games like Prototype, Bioniccommando, Godfather2, PrinceofPersia, NFSUndercover my PC shuts down at the specific time.

Im thinking that gpu is heating, can you confirm if this is the case through your experiences?

Weird thing is I was able to play Darksector, webofshadows, origins:wolverine, sf4

Playing
Thanks

Would be really nice to list the rest of your PC components ( don't leave out the PSU ) , the OS , tell us whether or not the case is well ventilated or not , and so on and so forth .
Sounds to me it's either overheating or your PSU cannot supply enough power to your PC .
Oh and tell us the temperatures the card was at ( aswell as the rest of your PC components , ie the CPU ) while it shut down .

not all games draw the same amount of power

i had an ati card that was starting to go

if i played a newer dx9 game at the time...it would go down
if i played an old dx7 game, i could play forever and ever...

Thanks for the replies guys

Got:
athlon X2 5600 + gigabyte gpower 2 cooler
msi k9ngm4 micro atx
80GB seagate HD
sony DVDRW
1 kingston 2GB DDR2 800
win7 ultimate

Case has:
a 12cm intake fan on the side
a 12cm exhaust fan at the back
a 8cm exhaust fan at the back
Generic powerlogic 500W PSU

Used rivatuner to check gpu core temp and it was 63C at idle and went up to 66C-678 while running godfather2 and NFSUndercover

Then I highly doubt it's the heat . Most likely the noname generic piece of crap PSU you have is starting to die .
I suggest you acquire a decent PSU ( ie a 500-600W Fortron PSU , fairly cheap and quite good ) .

Thanks Radiator
Will try to get a branded one when I get my pay check next week
Im thinking of getting Thermaltake 550w or 550W Gigabyte Superb

While waiting, used rivatuner to lower down core and memory to default 8800gt clocks (palit sonic version was overclocked) and was able to play godfather2 continuously
Temp went down to 55C at idle and 61C while playing

did you check to see how warm the card gets

with these game ??

"Weird thing is I was able to play Darksector, webofshadows, origins:wolverine, sf4"

(you'd have to bring the card back up to speed)

just to see if it is the temp of the card
and not the power supply

His cards temperatures are WELL WITHIN SAFE LIMITS .
If it shows 61 degrees just after closing the game , it couldn't have been much higher while playing .
Then again wouldn't hurt checking anyway .

I don't see the temps getting high enough to damage the card, but you'd be surprised at how fast core temps can drop when they go from stressed to idle.

I'd try and run four instances of rthdrbl (spaced evenly covering the whole screen) and try checking the temperatures WITH them running.
