Hello... i never really seeked out help on forums before, not for this kind of problem atleast.. But i thought id try it out since i know nobody who can help me with this issue..
Recently i changed my graphics card from a 8800GT 512md ram overclocked edition, to a 260GTX 896mb ram.
I was in doubt whether my old power supply could handle this (450Watt), but the guy at the electronics store said it would work.
But.. heres the problem :
I played a few diffrent games with the new graphics card, such as Crysis and Farcry 2. There was no problems with this, it was running smooth. But then a few days ago i bought Call of duty modern warfare 2, the game itself is running smooth with everything maxed out exept for anti aliasing, but after a half hour to an hour the computer instantly shuts down. When i turn the computer on again, the only thing it does it that the option to choose "safe mode" or "Run windows normally" comes up, but then it starts up without further problems.. But it just keeps shutting off when playing call of duty..
I have run alot of test programs on it the last couple of days to test if this is a heat problem.. I tryed running Prime95 to test the CPU stability and it seems that it can just keep running with a stable temp at 68-71 celcius ( i know this is a rather high temp but the CPU is overclocked quiet a bit.. ) At normal use such as gaming or surfing on the net the temps are 41-55 celcius.
I also tryed out 3Dmark vintage and nvidia Ntune to test the graphic card..
Then i tryed OCCT to test both CPU and graphics card. The CPU could again run at a stable temp doing the normal OCCT CPU test.. But if i ran the Linpack test the CPU got too hot and the test stopped automaticly.
The GPU test ran at a stable temp of 84-86.
I also tryed out the power supply test in OCCT and nothing happend there either.. exept for the CPU getting kinda hot.
I also tested the RAM with MemTest and it showed no errors..
My suggestion is that the power supply is either not strong enough or broken.. But the weird thing is that i have only tryed the computer shutting down in Call of Duty MW2.. not in Crysis or any other game..
I dont think there is anything wrong with the game itself.. i have reinstalled the game once to check if that would fix the problem and i have run validation thing in Steam.
I seeked out this forum becouse i wanted to check if somebody knew the solution to this problem.. At the moment my only idea is to try and buy a new power supply and see if that works.. But it would really suck if it didnt help a bit :< becouse i find that good quality power suplys are rather expensive.
Here are my computers specs :
Power supply: Chill innovation CP-450A4 450Watt.
OS: Windows 7 Home Premium 64bit.
MotherBoard: Abit IP35 Pro.
CPU: Intel Q6600 2.4ghz overclocked to 3.5ghz.
RAM: 4x1024mb OCZ DDR2 PC2-6400 System Elite Dual Channel 800mhz.
Graphics: XFX Geforce 260GTX 896mb.
Hard disk: WD Caviar Blue 320gb 7200 RPM.
DVD drive: Dont know anything about this one.. can find out if needed.
Please any help would be very much apreciated.. before i run out and buy an expensive power supply.
I am sorry if some of the info is not useful or not well explained. I am kinda new to forums. Also i was a bit in doubt wich category to put this post under..
