Ok problems only started recently

When playing more graphics intensive games, it crashes or more accurately freezes. Computer does not blue screen or reboot it just freezes.

I thought it might be a heating problem so i bought extra case fan and put normal fan onto internals. No luck still freezes on occasion.

I figure it may be PS as its only 300W, however my computer is not really running that much stuff only 1HDD and a cd burner.
Any IDEAS?!?!

Problem 2 , computer will not reboot properly, when instructed to reboot seems to go to standby, (monitor power down, computer stays running, does not reboot) any idea?!?

Last problem ( i know i should throw it out the window and start again, however) When I try to reboot it sometimes it does not boot properly, fans will start going, but HDD etc does not fire up. MB does not *beep* and monitor does not fire up.

Again any help would be greatly appreciated. I figure it could be PS or graph. card.

Thanks guys
