Ok so i have a odd situation; i just replaced my graphics card, my old one was a 8800gts 512mb and i upgraded that to a GTX 460 768mb. The reason for the upgrade was because i have a dual screen set-up (a 32in & 23in) and my 32in would no longer display video, but both screens display video when plugged in by themselves. So now im starting to suspect my PSU which is a Rocketfish 750 watt. Now when i shut my pc off for the night with just one monitor plugged in and turn it on in the morning it boots with no video signal, so i reset the cmos and load my saved cmos settings, all boots fine after that; until i shut it off for a little while and turn it back on. I do not get BSODS at all.
Below are my system specs, my CPU is overclocked to 3.0Ghz, my memory is OCZ Fatal1ty.
Mobo? BIOS version? Tried updating the BIOS? Have you changed the PCI-e voltages for an old overclock or anything? If it is hanging and not even passing POST then it sounds like a BIOS problem...not for sure but likely.
