Have you shorted the jumper? It should be a three pin with a small piece of plastic (with metal in the middle), covering two of the three pins. It should be located somewhere near the cpu socket, you'll just have to look for it. To short the jumper, take the piece off and move it to the opposite two pins. Return it to the original position, and give it a go. I would do this with the battery out, and the PC unplugged from the wall.
heres the cmos jumper instruction:
*1-2 - normal (default)
*2-3 - Configure (after POST runs, the BIOS displays the maintenance menu. use this menu to clear passwords)
*(none) - BIOS recovers data in the event of a failed update
theres nothing about clearing CMOS there, plus the failed update option didnt work.
the pc keeps boot looping
have you tried different combination's with your power supplies sata power, as well as different sata cable positions? Try plugging your boot drive into a different sata port. Unplug you dvd rom if you haven't already.Try different cabling for powering them on as well if all else fails.
What was going on before it stopped working? Did it crash, or did it just not boot one morning?
After many different possible solutions tried, the prob was solved. i had to remove the mobo from the case, install a different cpu. then it was all (my old i5) back into the case (i had to remake all cabling ) and PROBLEM SOLVED! not sure what was the problem though...
