CAn anyone help me?

Can you describe your particular problem please.

well during any full screen game after about 10 minutes my power well just shut off on my pc and i have to remove the power cable and put it back in to get the computer going again.

Sounds like a heat related problem to me, when is the last time you opened up the case and cleaned all of the dust out with compressed air?

not any time soon, what is the best way to clean it? And i was thinking of getn some sort of cooling system any ideas?

What is the make & model of the computer?

Do you have the manual? Are you familiar with opening the case?

A can of compressed air is good for removing dust: for example:

Canned air is compressed air in a spray can with a very long nozzle that enables a precisely focused blast of air for cleaning delicate or sensitive things. Because jets of air are more effective, and yet gentler, than other cleaning methods, canned air is often used for cleaning computer keyboards and the insides of computer cases.
Dust is attracted to electronics in general because of static electricity; this quality, combined with the circulation of air created by the fans in a computer case, means that impressive quantities of dust can collect in a surprisingly short time period (depending, of course, on the amount of dust in the area). If dust is not removed from electronics, it creates an insulating blanket and can lead to over-heating and damage to circuits.

Knowing the make & model of computer would allow us to search for upgrade & modification options.
