Hello i recently put a shaman on my gtx 460 and put some more voltage to it in increments and moved up the core clock. I had it going up into the 860s and i was testing with evga oc scanner for 3 minute intervals. then it restarted on its own and now it will not boot up. did i fry my video card?
Turn off your computer, unplug power supply and chords, and find the jumper for CMOS. Touch the case to discharge static, then move the jumper to clear position (usually pins 2-3) for 15 seconds, then set back to normal.
IF you set it to boot on those clock settings, this should get you to BIOS where you can change that back.
well since i am not under warranty i might upgrade to a 570 is there any good vrm cooling for that card? i will try your suggestions to see if my card has a chance or if its burned up. thanks for all the advice
