My PC was running fine until I tried that auto O.C. programme that comes with ASUS A.I.suite. I set it to 3.6 and then pressed the select button which would normally turn the PC off and on again. this time when it turned off it stayed off and the mobo board lights went off as well although the battery was still connected. The CPU i5 3570, MOBO Asus MAX V and RAM are only 2 months or so old with very sparse use. The battery is about 4Yrs old Antec 650W . CPU is water cooled, no leaks. Before being turned off the PC was running all the night before and all day the next so rough guess 36 hours which is normal as I usually leave mine on 24/7. It was just web browsing and watching films and downloading some stuff for the most part so nothing too strenuous going on before the problem. Any ideas anyone ?
This probably is obvious, but have you tried leaving it unplugged for a while and doing a cmos reset, battery out for a few minutea? Could be a locked transistor or something?
Yup reaet the cmos. Some motherboards actually have a button for it, but otherwise pull out the battery from the board and unplug the pc from the wall. Leave it like that for 5-10 and put it back in and try again.
I think you're in to fault finding territory now, one stick of ram, gpu out, unplug all power bar 24 pin and 4/8 pin for cpu and see if it boots is a good start point imo Also, check fuses etc
