My pc is facing this very weird problem.
So until 3 days ago. It was working just fine. I was gaming like usual. Nd then i shut it off after an hour of gaming.
But when i tried switching it on the next day it wont boot up.. not even the bios screen comes up.
So firstly i tried resetting the bios nd then afterwards it worked fine but after i shut it down nd then again switch it on, it dosent boot up.
Then i removed the gpu nd reseated the ram nd removed the additional hdd, optical drives etc. The computer works just fine without the gpu.... Today i reseated the cpu, ram, gpu. Cleaned it nd reset the bios. But again it wont boot up. But if i press the reset button of my cabinet then it boots up some times nd if i shut it off the problem reappears.
The cpu fan spins very fast nd then slows down to normal nd just keeps spinning. The mobo speaker dosent beep, keyboard led dosent light up, mouse led dosent light up, only power led lights up.. hdd led lights up once nd then goes off. I tried resetting the bios a dozen times nd it fixes the problem some times but after a full restart, the problem appears again.....
But everything works fine with the gpu removed. I removed the gpu nd switched on the pc nd then checked the HWMonitor voltages. All voltages were below what it should be. 8v on the 12v rail, 3v on the 5v rail. Nd 2v on the 3.3v rail. Nd when it does power on after a dozen tries. The bios shows there is 12.4v on the 12v rail.
P.S.- Even the mobo logo dosent show up. Just the cpu fan keeps spinning.
Mobo - Gigabyte h61m-s (rev1.0)
