Hi,

I'm having an issue with my PC (Windows 11), it was working fine then after a reboot I'm just getting a black screen.

I don't see the BIOS boot screen and holding down F2 does not bring up the bios. I can see the LEDs come on in the PC, plus the keyboard and mouse LEDs light up, go out and come back on again, which is what they do as it boots normally and the monitor displays a blue power LED for a while before switching into power saving mode. There are no beeps but don't think it tended to beep anyway.

I can see the computer on my network, but trying to remote desktop to it tells me there is already a session in progress.

Any thoughts or suggestions? Wonder if graphics card is an issue, but then seems strange that I can't remote desktop to it (though don't think I've tried to before, so may not be connected)

The specs are:

Intel Core i7-13700k
ASUS TUF B660-PLUSWIFI D4 Motherboard
ASUS 4080 TUF Graphics card
Corsair RM850x 850w power supply
Samsung 980 Pro 2TB SSD (Two of them, independent, not raided)
2x16GCorVenRGBPRO SL 3600

Annoyingly I see I had a 3 year warranty, that expired less than 2 weeks ago!
 
Doh! Turned out it was the monitor, plugged cables around to try a different one and realised it worked, so tried unplugging the problem monitor from the mains and plugging back in and that seemed to fix it! Very glad about that, did not want to be replacing PC parts with prices like they are at the moment!

Thanks for the suggestions, got me fiddling around with the cables, though surprised I hadn't picked up on the monitor thing as guess it wouldn't have been working for my second PC (2 PCs, 2 Monitors and a KVM switch set up that I can switch between dual screen for either PC, or one screen per PC)
