Windows 7: HDMI Monitor Not Receiving Input

HDMI Monitor Not Receiving Input

Hey guys, for the past four years I've been running this computer, along with a 1024x768 Curtis monitor and a 1280x720 Vizio monitor. Up until now, I've had absolutely no problems with the dual monitor setup, both running off the GeForce 610.

Yesterday, however, the Vizio monitor, connected via HDMI, randomly stopped receiving input. The Curtis monitor (connected via VGA) still works fine.

What I've tried:

- Rebooting my computer, nothing. (I rebooted after all of the following attempts as well)
- Going to Screen Resolution and manually detecting another monitor. Nothing was detected.
- Going to Device Manager and scanning for hardware changes. Only the VGA monitor is listed as a "Generic Non-PnP Monitor", nothing about the HDMI monitor.
- Updating graphics drivers. I used the built in Windows driver updater, nothing. I used NVIDIA's site and downloaded the recommended driver, nothing.
- Switched the cables between the two monitors, the VGA monitor works while the HDMI monitor does not.
- Tested the HDMI cable with an Xbox, works fine (cable is working).
- System Restore to several days ago when both monitors worked, nothing.
- Booting in safe mode, nothing. (don't think this would work anyway... I tried...)
- Removing and cleaning graphics card, nothing.
- Attempting to detect the monitor via NVIDIA Control Panel, nothing.
(from here on out is random desperation, I really have no idea what's wrong)
- Running sfc /scannow in the admin console finds corrupt files, but is unable to fix them. CBS.log contains a 3.7MB text file filled with 26,442 lines of output I don't understand. Might need some help on this one, though I don't know if it's related to the monitor at all.
- Running CHKDSK in cmd returns 0 bad sectors on the drive.
- SUPERAntiSpyware found only 8 tracking cookies and MSE found nothing.

Any help you guys could give is vastly appreciated, I'm stumped on this one. Extremely sorry if I accidentally broke any rules on this thread, this isn't something I do often.

Very slim chance but does help sometimes: un-plug PC and monitors from power mains and re-plug after a minute or two.

Also try loading defaults in BIOS.

HDMI Input
My new PC monitor has a HDMI input slot. If my video card had a HDMI slot would it make any difference in video quality or is the HDMI just for use with a TV? Thanks,
