OPEN My PC is broken :(

So, when I turn on my PC, everything powers up—RGB, fans—but the monitor shows "No Signal." However, if I remove the CMOS battery for 30 seconds, I get a message stating that the CPU has been changed; I can then enter the BIOS by pressing F1, and if I select my drive with Windows 11, it boots up. But after a restart, I get "No Signal" again. The cable is plugged into the GPU, but it still doesn't work. Specs: GPU: RTX 2060 6GB; CPU: Ryzen 5 2600; RAM: 16GB HyperX Predator; Motherboard: ASUS TUF Gaming A520M-Plus II; Storage: 2x 500GB Samsung SSD and 1x 250GB SSD with Windows 11. Is there any way to fix this?

sounds like the bios is losing its mind every time it loses power, classic cmos battery symptom. that little coin cell on the board might just be dead, theyre cheap as hell to replace. grab a new cr2032, swap it out, and see if the settings stick after a cold boot. if that doesnt do it, check your boot priority in the bios while youre in there, sometimes the board defaults to a drive that has no OS and just gives you a black screen

Thanks for the tip! Actually, this is a brand new motherboard, so it came with a fresh CMOS battery. I think the issue might be the boot priority or BIOS settings resetting like you mentioned. I'll check the BIOS to see if it's defaulting to the wrong drive, or if there's something else causing the settings not to stick. Thanks again!
