well i will say your first initial issue was that putrid abit board.
the 680i was not one of abits better devices. not that i ever saw, but i didnt hang around to watch it get fixed or not.


alot of things can make a pc go bad man, even your mouse,, believe it or not, i have seen mice and keybaords do all kinds of wicked wierd stuff.

next is your overclock. stop overclocking and set it all up on defaults.
bench it, cpu, ram everthing make sure its stable if not adjust your voltages but not too much as defualt settings on that stuff should be pretty close to auto.


what i am going to ask for is what are your current bios settings and what is your current overclock.

you can also lookinto a bad power strip or surge suppressor, if your using a battery backup then dont.
a bad battery backup can cause all kinds of crap to.

start out by IN DETAIL listing the bios setings you are using. and i dont mean just overclocking i mean everything.

take the time and take some pictures and upload them to image shack. or host them somewhere.

let us help you if you are going to ask us for help.
