o, normally when I play video games or even sometimes browse around on the internet, my monitor will black screen, saying "No signal". Once I try to restart, it won't let me. Trying to hold down the power button won't work and the only way to turn it off is to flick the PSU switch off. I don't know what the issue is, I've reset my BIOS, updated my GPU drivers, updated my BIOS, checked the PCI-E slot, checked my RAM, and can't find what is causing this. Any help/suggestions would be appreciated.
