Update: Broken motherboard and/or CPU.
Hello,
I am having an issue where as soon as I power my 6-year old computer on, it shuts off after 1 second.
Then, it attempts to turn on again, but shuts off again, and the cycle continues until I hold down the power button.
I removed all USB devices, all PCI/PCI-e devices, all SATA devices, all fans (but the CPU fan/radiator), one RAM module at a time, and the issue still continues.
I suspect that the culprit is the power supply. I shorted pins 15 and 16 (power supply stayed on) then used a multimeter to check all voltages, and they are all within acceptable range, but I have my doubts about whether it means the power supply is fine (as there is no load).
Leading up to this, in the past month, my computer has restarted by itself without explanation once or twice a day.
Unfortunately, I do not have any spare computer parts lying around, and I'm pretty isolated where I am right now.
Should I take a gamble and order a new PSU, or could it be another part that's causing the issue?
What other tests should I try? As a matter of fact, could it be the CMOS battery (no data lost after startup, so I personally doubt it)?
About 10% of the time, the computer does start up successfully, either on first "attempt", or after a few attempts.
Built in June 2014, used for moderate gaming, video editing. All parts but CPU and PSU have been upgraded since then.
OS: Windows 10 Pro
CPU: Intel Core i7-4790K (with Corsair H60)
Motherboard: Gigabyte Z87X-D3H
Graphics: NVIDIA GeForce GTX 780
RAM: 16 GB (2 x 8 GB DDR3)
PSU: Seasonic S12II 520W
Storage: 1 TB Corsair Force NVMe SSD (via PCI-e Adapter), 512GB Samsung 850 Pro SATA SSD
Thanks
