Hello guys, I have a problem with my custom build right now. I have this build for 1 year and it never occurred any problems until now.
When I start my PC from the first time, everything runs fine and good. But when I shutdown my PC (not restarting) and try to boot again, the PC doesn't POST. The CPU fan spin and it seems to be working correctly but it never reach BIOS, so I need to unplug the main cable and wait for some minutes (10-30 minutes) to be able to boot the PC correctly again. Its worth to mention too that sometimes when the PC can't POST it enters on a infinite loop state, powering cycling on and off, staying 2-3 seconds on and powering on and off.
I have tried numerous solutions but none of the seems to have worked. So far I have tried to:
- exclude all the unnecessary hardware to reach BIOS, leaving only CPU, fan and RAM.
- swapped with two different PSU but the results were the same.
- testing the two sticks of RAM in another computer and it worked perfectly.
- clear the CMOS battery. (My motherboard doesn't have the CMOS jumpers)
- breadboarding, same problem.
So with all this tests I'm sure that the problem seems to be coming from the mobo or/and the processor, but I don't think the processor is at fault here because sometimes my computer boot and runs flawless. I'm almost sure the problem is coming from my mobo, something relate with the capacitors not being able to discharge correctly after a shutdown.
Anyone got a better idea?
My specs are:
Gygabyte H81M-H LGA 1150
Intel i3 4170
2x 4Gb RAM Modules 1600MHz
Powercolor AMD R7 260x
Corsair CX 500 80plus bronze
Samsung HDD 5400rpm 1TB
Sandisk SSD 240Gb
Thank you for your time!
