System Shutdown 30 min into COD Black Ops?

Evga / 465 gtx sc

Specs: Windows XP, Q9450 / 4GB
This is very odd, I am running an nForce 780i SLI motherboard, with a Q9450 quad core processor, 4GBs of DDR2 Ram, and an EVGA 465 GTX SC Card (recently upgraded from a 9800 GTX+). I had a Corsair 550W PSU. I picked up and started playing Call of Duty: Black Ops. Thirty minutes into the game, without warning, the computer completely shut down, it did not show me any error messages or slowly shut itself off (no blue screen, or game crash), but rather just shut itself off completely, as if I just pulled the power cord out of the wall.

Last week, I did some google searches and deduced that I was getting too close to the minimum power requirements for my specs (although the PSU calculator said that I was within 50 Watts of the safe level). Hence, I have upgraded to a Corsair 750W PSU. I finished installing it about an hour ago. Thirty minutes into Call of Duty Black Ops, the same thing happened. The computer completely shut down, it did not show me any error messages or slowly shut itself off (no blue screen, or game crash), but rather just shut itself off completely, as if I just pulled the power cord out of the wall. This only occurs when I am playing a game (although I have not tried to play any others since I installed the 465 GTX SC). All my other functions (many windows, tabs, programs running without a single issue) run fine. What can be causing this, and how do I fix it? Any help, would be much appreciated.

Thanks, Jose

Right click my computer>properties>system properties window>advanced tab>under startup and recovery click settings>starup and recovery window appears, under system failure untick automatically restart then ok. Try to run a game. Did u un-install the old driver before installing new one? Also check cpu temp in bios.

Your problem is most likely due to the GPU overheating. I had the same problem and the 2 biggest causes was either the CPU or GPU (graphics card) over-heating. I bought a cheap fan and pointed towards the video card and it cooled it down enough to not do that any more.

call of duty black ops is known for its bad reviews its lags and weird problems
as for the shutdown ur pc as mentionned b4 by kuwese might be checked system restart or ur hardware are not getting enough power from the power supply
750 W psu is not a psu mention the amps on the 12V rail ur pc hardware might not be getting enough power

computers are a second home
