So the other day I assembled all my PC components and booted up after adding components one at a time to see how the PC responded. I eventually had everything in the chassis running perfectly fine. I finished up my cable management, closed up the case and left the computer updating windows 10. Unfortunately, after I came back to check on the updates the PC was turned off with the inability to boot up again... Nothing! No signs of life whatsoever. I proceeded to take out one component at a time and reduced my build to its simplest state. (i.e. 1 RAM stick in primary RAM slot, CPU, Mobo and PSU). Each time a component was taken out I attempted to boot. Still nothing. I've tried each stick of ram individually, and that all PSU connectors were properly seated to the Mobo. Nothing has worked so far.
Now this is where it gets weird, as I've never seen this before... Since my issue had started I have had 2 successful posts in which the PC will start and stay powered on for a max of about 5-10 seconds. This only happens after I've left the PC alone/unplugged for quite some time. Once it booted after few hours following failure and another time after a whole night.
As far as I know the only thing about the PC that changed between working and non-working states is that I closed up the case. After the most recent successful power up I heard a funny sound (which I cant really describe) seeming to come from the general location of the PSU right before it shut down again.
Full PC Build:
Processor: Intel i5 8600k 3.6 GHz 6 core Fan: Noctua NL-L9i CPU Fan (FYI: Thermal paste applied appears to cover about 75% of the CPU when not heated, this is the first time I've installed a 3rd party fan).
Motherboard: MSI MPG Z390 Gaming Plus
Graphics Card: Nvidia Geforce GTX 1070 6 GB
RAM: CORSAIR - Vengeance LPX 16GB (2x8GB) 2.6 GHz DDR4 DRAM
PSU: Corsair CX750M (750W)
SSD: Samsung Evo 860 500 GB
Case: Phanteks Ecplipse P400S
I'm thinking/hoping this is just a PSU issue or some overheating issue. What do y'all think?
Thanks
