Hi I've got a GeForce FX 5200 and an AMD Athlon Processor that goes at about 1.20 GHz. I overclocked my videocard a couple times with PowerStrip just to be able to play Doom 3 demo smoothly. After using it a couple times I tried getting 3DMark '03 to work but after the test game loads, my computer automaticly restarts. Anybody have any solutions? Btw, I've been running my Engine clock at 292 MHz and my Memory clock at 376 MHz.
