Battlefield Bad Company 2 and Crysis 2 have caused my computer to totally shutdown without warning after about 20-30 mins of play. Then after maybe 3-5 mins after the shutdown the computer restarts its self. First game I installed into this machine was Shogun 2 and I did not have a problem with shutdowns. However I haven't played that game in awhile.

Anybody else having these problems?

Am going to format harddrive and reinstall windows 7 and keep you guys posted.


Intel Core i5-2500K
COOLER MASTER HAF 932
CORSAIR Enthusiast Series TX750 V2
2x G.SKILL Ripjaws Series 8GB DDR3 1333
MSI 6950 2gb
HITACHI Deskstar 7K3000
Crosiar THX 750

After reading through online. It could be multiple items. Guess I'll try it when I get home and keep you guys posted.
1. Format harddrive and fresh install of Windows 7 ultimate.
2. Stress test ram with Mem86+
3. Go to best buy and purchase a power supply.

Hopefully I can find the problem and let anybody that has a similar problem find a solution.
 
Don't get a power supply at Best Buy. You'll pay too much and come home with a piece of junk Rocketfish or something.

Try CPUID HW monitor to check your max temps while your gaming. 34-40c during gaming is VERY low, it's either an incorrect reading or your room is unusually cool.

Alright I found the problem. Seems my MSI 6950 2gb video card was not cooling effectively with the auto fan. Had to manual set the fan at 60. Which kept the card at 65 C max settings for crysis 2. On auto the card slowly but surely reached 90 C which made the computer shutdown.

However, I read online that 90 C on a 6950 is normal under full load. Should I contact MSI and ask for a RMA? Kinda of annoying that I have to manually set the fan speed everytime am going to game. Temporary fix I guess. Fan is considerably loud at 60% :(
 
I run my fan at 40%. When I game I run it at 60%. Yes it's louder, but that's how it cools better. Higher RPM= better cooling.

There are programs you can use that automatically raise the fan speed when the gpu hits a certain percent of load, like afterburner.

However, 90c gpu temps would not cause a computer to shut down. High cpu temp or overloaded psu would. I'm not saying your psu is overloaded, just that it would be a symptom of that.
