Earlier today I accidentally pressed the bios flash button on the back of my desktop, and now when my computer boots up there's no signal from my monitor despite it working perfectly before. I've tried clearing the cmos/bios, restarting my computer several times (with and without inputs plugged in) and I even took out the cmos/bios battery and put it back in (as recommended online) but nothing has worked. Last time this happened my monitor randomly started to work again but this time nothing is working at all. Do I maybe just leave it on for a while and see if it eventually works? Please help
