Hey guys, i apologize in advance if this is in the wrong section. My comp has a nvidia geforce 6600, i came on here earlier today to learn how to overclock(im definetely a newbie), ive downloaded coolbits and all that and managed to overclock the settings from the default 300/500 to 400/553. I tested numerous games and everything worked fine i tried to up it to 410 and it worked fine then when i tried 420 the game seemed to work fine then it froze on me. i restarted my computer and now windows starts up to the loading screen with the little bar underneath and after its done loading it flashes the blue screen and the comp restarts itself?? I have no problems getting into safe mode and when i try to click on the nview display settings to lower my overclock the display wont show up.. any ideas or help would be greatly appreciated thanks in advance.
