So I've been using this computer a few months now, built it myself on these forums.

I have been to bios many times of course especially while configuring the system originally.

But now for some reason when I reboot the monitor goes to sleep(no signal) while it's booting, until the windows loading screen then it turns on like normal.

The biggest issue I have with this is that I cannot enter BIOS since I can't see anything during boot. If I hit DEL while it's booting it will just stay no video forever (because probably in settings but I can't see anything).

Anyone have any idea what's going on?
