Hi! Today my PC suddenly shut down. After that it just freezes after showing the logo screen, so I can't even enter the BIOS.

There were no bios / hardware / windows updates before that.

I tried to:
- reset BIOS by removing the battery
- remove everything except cpu, memory & video card
- switch back my older memory dimm & video card

None of it helped..

After showing the logo screen, the keyboard remains responsive (like I can turn on&off caps lock for ex), the coolers are running (both cpu & video), LED lights are blinking.

What else can I try to check? Please help!

disconnect the SATA, M.2 or USB cardereaders connected to the board.
Then the system should always go into BIOS.
Also use a cabled USB keyboard and mouse for the test.
If this works, there is probablyu something wrong with your bootdevice.
Electronic media like M.2 and SATA SSD, can suddenly fail.
Kind Regards
