Uncontrollable restarts

[stealthbig]

Recently when I play Dungeon Siege, and when the game starts and the monitor kind of goes black when it had to change resolutions, about half the time it does that the computer restarts. Im not sure if im overloading the PSU you what. Its a 250 watt PSU and im running a 1800 athlon, radeon 9000, 2 cd drives, and 2 HDs.. is the problem my PSU or something else?

Yes, it's your power supply. I'd bet 20 dollars on it. Get an Antec TruePower series, at least a 350 W, or an Enermax.
