I accidentally pressed the clear cmos 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, and I've figured out it's not a monitor issue. I've tried clearing the cmos/bios, restarting my computer several times, held down the power button and clear cmos button for 30 seconds (with and without inputs plugged in), tried taking out the cmos battery and waiting 30 minutes (+ unplugging graphics card and hardrives, as recommended online). Lastly, my bios flash button isn't lighting up, so I don't think I can properly boot my pc with an updated bios via usb stick (which I tried). This happened before once, and that time my monitor randomly started to work, but this time now nothing has fixed it. Should I just go to geeksquad or does anyone have any other ideas to fix it? I've never been unable to fix a troubleshooting issue like this before, I'm completely stumped. Would greatly appreciate any help, thank you.
