The specs of my computer are below. I recently installed SpeedFans and ATITools and discovered the following: MAX CORE "Crash because of too high overclock? Last working frequency was: Core 428.63MHz - Memory 492.75MHz MAX MEMORY "Crash because of too high overclocking? Last working frequency was: Core 398.25MHz - Memory 523.13MHz. It froze twice in the past hour. Once i was just sitting here(before programs were downlaoded) and it just froze(no game open). And it just froze when i rebooted right away. I don't get it. Its starting to lock up on me more and more. Do i need to purchase a new gfx card or a new power supply?"
