Random freezes followed by self-restart,no video output, no power in peripherals

[Fikowned]

So a couple of days ago I replaced some case fans on my pc. Booted down, power off and unplugged everything. First boot after the putting the power cord back in , I get no video output on my monitors and also no power to the mouse,keyboard and headset. After hours of tinkering around the only thing that worked is putting the gpu in another pcie x16 slot and removing the cmos for about 10 minutes. I proceed to put gpu back in the pcie gen 3 slot. Pc worked fine for about a day and then today i got a random freeze while browsing. PC completely unresponsive , restart button didn’t work, nothing. After about 10 seconds it restarts on it’s own with again no video output and no power going to the peripherals.I built the pc early 2017 and my specs are:
Asus H170 -Pro
I5-6500
Corsair vs550 (only 80 plus white certified)Gtx 1060 3gb
16Gb ddr4 2133Mhz
Windows 10 Pro (Latest version)
The only things I’m doubtful of are the PSU or the motherboard not being able to properly deliver power to other parts of the system. Does anyone have any suggestions? I turned off C states in the bios after the 2nd restart, but I doubt it will help if the issue is more concerning

Hello

Ot is possible it is the psu..reviews show it to be a mediocre psu..

even if it is mediocre, wouldn’t I have issues earlier? the setup isn’t power hungry at all from early calculations

Could be a coincidence it happening now but VS = value series and these are not intended to be used with anything more than either integrated graphics or the most basic of add on GPUs that are only any good for school or office type work.

Remove the GTX 1060 from the MB and connect the screen to the appropriate video port on the MB and see how that goes.

The thing is , I already tried getting a video output using the integrated gpu via hdmi and dvi, but was getting the same results (no video signal and no peripheral power). The ONLY thing that worked was putting the dedicated gpu into the other pci slot and removing cmos for a short amount of time

Excuse me for suggesting something that you did not mention in either of your two posts

So far so good, no random freezing and restarts. If it happens again , I’ll look to invest in a decent power supply, and if that doesn’t solve it, then it has to be the motherboard
