Shuts down my system

[nubreed]

i just reformatted my whole computer just thinking it was my computer but,
whenever i play the game like 5-15mins into the game my computer shuts down. i have nothing running besides the game. and once it shuts down it takes 3-4 tries to even get my computer to boot up again.
Besides this game i have no problems shutting down on it's own.
Only thing i can think of is.. i have a geforce 6200... is this the problem?

I looks like your pc is over heating and it shuts it self down
It happen to me when my fan stopped working the same thing you get.

Either the PSU fan stopped (visible at the back) or internal fan(s) stopped would cause this.
Either way, it requires intervention by someone competent, hardware-wise.

Do NOT for any reason, try to put oil or grease in the fans with the idea that it could fix it.
This seem laughable, but I worked in several jobs as acomputer repair engineer, and I have seen PCs, which would otherwise have been repairable, been written-off due to ignorant DIY attempts at repair.
This particular solution to fans stopping caused oil/grease to spread inside the computer, infiltrate on motherboard and various cards, which is terminal since those oils/greases are generally NOT electrically isolant. Some are highly conductive.

The ONLY solution to fan failure is to replace the faulty fan (wear and tear) with a matching model (not just any fan).

So basically it's my fan right? Which type of fan would i need to get?
Is this the same as my power supply?
Just to say again this shut down only occurs when i play Fiesta.
Also after I formatted i used a program called spybot. When i do a full scan
it shuts down my computer at a certain point of the scan.
I thought everything would be fine if i format my whole computer.
I have a Pent4 3.0, 1g ram, a geforce 6200 .
I'm so lost help me please!

Definetly sounds like an overheat problem.

All you may need to do is get a can of compressed air and blow out the fans on the power supply, CPU and graphics card. Also you may need to use tweezers to get out bigger dust bunnies caught in the fan.

The reason it's shutting down is things like spybot and this game use a lot of processing power. So my guess it's most likely the fan on your CPU.

This is something you should do with the computer off. (Had to say that as I know of people who've tried it with it on....)

It sounds like a overheat problem, But could also be a power supply problem.
