[SOLVED] PC auto starts and no screen or beeb

[ManoAamer]

Hey guys,
My PC starts alone when I switch my power supply on and it doesn't shut down from holding the power button it closes only when I switch my PSU off.
There is no signal in my screen and no startup beeb. I tried starting the PC with no components at all but still same problem happens

Specs:
PSU: XFX pro550w core edition
MoBo: Gigabyte AB350 Gaming 3
CPU: Ryzen 3 1600
GPU: MSI RX 580
RAM: 2*corsair 8GB 3000MHz

Update your post to include full system hardware specs and OS information.

PSU: make, model, wattage, age, condition?

Do you normally use the power buttons to turn off the PC?

You should be using the Windows power icon to shutdown the system. Doing so allows Windows the opportunity to do housecleaning and other OS related tasks to prepare for the next boot up.

Hard power off's may cause file corruption.

After the next successful boot run "sfc /scannow" and "dism" to hopefully find and fix problem files.

I don't use mu power button to shut it down no. It was working and I left it for like 2 weeks and when I am home this happened

If you were gone for two weeks then Windows may be trying to catch up on updates, backups etc. that were missed and require a restart.

Turning off the PC during that process may have corrupted some files.

Try "sfc /scannow" and "dism". Allow Windows time to get things sorted out and fixed.
