I have been using the pc for about 5 days,and now i feel i got something strange with it.

here list of the problems :
  • suddenly turn off randomly,sometimes while loading,sometimes after i click my left mouse(i was to ran check error at ssd,but after click it…boom).
  • my computer won’t turn on while i connected any port at back panel of motherboard.
  • after turn off i need to re-plugging power cables to make it turn on again.
PC specs:

Ryzen 5 2600x
Asrock B450m Hdv
Geil Super Luce 8x2
Galax Gtx 1060 6gb
Corsair Cx550m (2 weeks old)

for now i suspect it was a motherboard short,or you guys have any idea??

Yep sounds like a faulty PSU, do you have another one to test?
Could also be an overheat issue, is your CPU cooler attached properly? Enough paste? Are the fans spinning?

At the next successful boot try checking Reliability History and/or Event Viewer.

Either one may be capturing some related error code, warning, or even an informational event.

Try another known working mouse on your computer.

Try your mouse on another known working computer. Determine if the shutdowns stay with your computer or follow the mouse.

= = = =

Otherwise, power down, unplug, open the case.

Use a bright flashlight and a magnifying glass to carefully inspect in and around the I/O ports - inside and out. Inside and outside the case.

Likewise check all other connectors, and cables for signs of damage: bare metal showing, melted insulation, cracks, etc.

I am thinking that there is a short.

Possibly heat related - contact occurring after something expands. Or vibration eventually causing contact.

I think it's either a faulty motherboard or a dying PSU.

Then go ahead and change out the motherboard.
