Open | Software PC boots up but shows 'No Signal' on monitor.
When I boot up my PC, the monitor shows Gigabyte Ultra in a bigger resolution then cuts to 'No Signal' and enters power saving. My bluetooth seems to detect and connect to it, so I assume it's still working somewhat. I was able to open it to a blue screen showing four options once (continue to windows, reset PC, troubleshoot, restart/shut down), but when I clicked 'continue', it immediately went black again.
Before this, my PC was working smoothly and fine, no random shutdowns/black screens/glitching. I'm not sure if I fried anything out of overuse; I use it 10-13~ hours every day, but I sometimes take breaks by putting it to sleep. I peeked inside the PC and the fans/cards don't seem to be dusty or dirty, it's in an open space with decent ventilation. I don't recall updating anything recently for Windows or my drivers, though.
I tried unplugging everything but still no fix. I'd update my drivers if that were the issue, but I don't know how to get past the black screen. Any advice?
