Hi there. I will try to make this short and concise. Have new MB, intel I5 8gb mem. All installed fine and has been running well for a few days. Last nite I completely shut off the power to tower due to impending weather. Would not reboot or power on later. (Powered thru UPS, AC supply or surge is not the problem)
Took the whole thing apart, out of case with just one stick ram and cpu. Reset cpu and mem. Reset CMOS.
Turned on power switch at power supply unit and shorted the poweron pins. Nothing, no fans spinning. BUT, if I quickly pull off the 24 pin power supply cable, and plug back in, then a quick short of the poweron pins on mb will get it to start! I repeated this several times, and the only way to get it to power up and post is to first quickly remove the 24pin cable, and pop it back on. But if I shut it down, and try to power up again, no good, until I remove and reattach the 24pin cable. It then boots up, mem looks good, gets back into windows, etc after I put everything back together. I am afraid to shut it off again! Is this something a bios update may address? Is there a weird bios setting?
Never seen anything like this before. Oh, and it acted like this with THREE different working PSU's! so it is probably not a psu issue.
Any help appreciated. Thx DSA
