I'm stomped atm…
System has been working fine for the past yrs until roughly a week ago.
First symptom was sudden complete freezes during gaming. Everything would stop except the sound. No input would be recognized, visual would be frozen, yet somehow the system is still running (spotify continues to play). Forced shutdown by holding power button then startup would bring it back.
It then got worse as days goes by. Until now it wouldn't even POST after a forced reboot like that. However, after shutting off power by unplugging psu for a while then trying again, it'll boot fine. Normal reboot from Windows is OK too.
Visual inspection all look ok. No burnt smell anywhere.
This is what I've tried:
- stress test with prime95 and kombustor will run ok for a while (10+min), then freezes and same thing happens
- breadboarding it with only CPU and different RAM seen to replicate the issue easier. It will boot, but after forced shutdown it won't turn on. The fan will attempt to spin then PSU immediately shuts off with a tick sound. Waiting some period after unplugging sometimes makes it boot again.
- used PSU to boot another machine seen to work fine
I'm looking to borrow a PSU from a colleague soon just to really rule out the PSU problem.
The above leaves the motherboard or cpu. Would any one have any idea on what might be causing this? Or seen anything similar?
It feels like a capacitor dying somewhere. Is this one of the sympyom?
Specs
CPU: i7 4770k
Mobo: Asus z87i-pro
PSU: Silverstone SST-ST75F-GS
RAM: G.Skill Sniper F3-1866C10D-16GSR
