I built the PC in December. This problem started maybe 4 months ago and has been getting more and more frequent in the last few months.
For seemingly no reason, when switched on, my PC won't POST. Instead the board will power up (with no lights) and the fans will run at a continuously higher rpm than usual. It will fail to POST, with no video output and will just sit there until powered off.
For comparison, when working, the board powers on at a slightly higher fan rpm for a second, then reduces to normal as the board lights up and POSTs with video output.
I don't get how it can be fine for weeks but then have 'bad days' where it won't POST and I'll have to power off over and over as it fails and falls to POST. Only way I can coax it into life is by switching off the PSU using the switch and leaving it for a while.
Yesterday I tore down the PC and did a complete rebuild, everything came out of the motherboard including the CPU and RAM which I reseated in different channels. But alas, it's still doing it.
My next step is to reinstall windows but I'm not sure how beneficial that'll be, I didn't think software was applicable prior to POST.
Any ideas???
Specifications:
EVGA GeForce GTX 1080 ti
Gigabyte Z390 Aorus Pro WiFi
Intel i9 9900k
2* Sabrent 1TB Rocket NVMe M.2 SSD
Corsair Vengeance LPX 32GB (2* 16) DDR4 3200 MHz
750W EVGA SuperNOVA 750 G3 PSU
Thanks in advance everyone
