I turned it on this morning the check stuff before work and it came up with "Warning bios recovery mode has been detected, please insert a usb device with P8Z77VLK.Cap" so I got the file, put it on my flash drive and updated the bios fine, Then it would start hanging with a blinking cursor instead of starting up windows after the bios splash screen, so I went into the setting and restored them to optimal default, after that I restarted then it just hung on the bios splash screen, no button I pressed was doing anything. After trying to restart again the screen was just black and not getting any signal, but the pc was powering on fine and my mouse and keyboard were lighting up. I tried resetting the CMOS, plugging my monitors into the mobo, and taking out and putting back in the CMOS battery. I've also tried checking the connections inside the pc and reconnected everything, refitted the GPU and tried resetting the CMOS one more time and still nothing. Again my keyboard and mouse light up, everything in the tower seems to be running but the monitor isnt receiving any signal.
