So yesterday my brothers computer turned off while gaming and it won't turn back on. This has happened before (6 months ago) and I ordered him a new motherboard which fixed the problem. Now it has happened again and I believe the motherboard is the culprit just like last time. Below are tests I have tried:
-Resetting CMOS (battery and pins)
-Tested all RAM modules alone
-Tested PSU with paperclip test (passed) and swapped in a known good power supply and the computer still wouldn't boot.
-Breadboarded the computer with only the mobo, cpu, 1 ram stick, and psu and no luck
-Breadboarded the computer with only the mobo, cpu, and psu no luck
-Breadboarded the computer with only the mobo and psu and no luck
For ALL tests the computer only turns on for .25 seconds before turning off. There are no beeps because it turns off immediately. The only thing that happens is lights flicker for that small instant of time. The motherboard backup power light (green light) does come on when the power supply is connected so I know it is receiving power. I have ran out of ideas and want to make sure I should RMA this new mobo (asus m5a99fx r2.0 -- yes a known good board).
