Question PC won't power on ?

[jayjay291077]

I recently changed my PSU after it died to a new Corsair modular gold + 750 but was a experiencing random freezes and reboots. I looked at my Windows error logs and found multiple issues so decided to do a clean reboot install of Windows.

Reinstall went fine then system would not shut down properly or restart after installing further software such as anti virus and LAN driver etc.

So I manually restarted the first time by turning the power off the back and reboot back into Windows. I installed graphic driver, rebooted and it hung up, so did hard reset. Now PC won't even power on.

I have tried jumping the power switch, nothing.

My specs:

asus b550 f rog mb
amd 3600 x cpu
corsair psu (psu is less than a week old)

My question is my PSU toast or is my mb toast or any other ideas ?

Thanks all

Try turning off psu switch, unplug from outlet, hold power button down for 30 seconds. Plug back in, turn on psu button then try pc power button. Do you get any power , light, readout of any kind from motherboard?
