2 Monitor Display Suddenly Freezes Computer - Can't Connect Via HDMI

I use 2 monitors (see below). Both worked fine for over a year then the digital monitor suddenly went blank and the computer now has problems booting and displaying. Everything works fine when nothing is connected by HDMI. Both monitors work when connected as analogs (one at a time because I only have one pin connection).

I have confirmed:

• There is no malware/virus on my computer.
• HDMI cable is fine (I have 2 new cables, and switching cables doesn't change anything).
• I think all drivers are up to date
• Windows 7 Pro is up to date.

Computer:

Dell Vostro 270s, Intel Quad Core i5-3450S CPU @2.80 GHz
Windows 7 Pro with Service Pack 1
Video card Intel HD Graphics Family

Monitors:

Samsung: SD24D300 digital
Dell E2011H generic PnP analog

Any suggestions?

System Restore to a date prior to the issue - System Restore

System Restore to a date prior to the issue - System Restore

Good idea. I tried several times before I figured out that it was the HDMI causing problems, but I couldn't get it to successfully restore. I'll try again.

If System Restore doesn't help, try running in elevated cmd:

Code:

sfc /scannow

Let us know if corruption is found.

Another thing you can try: download Linux Mint MATE and make bootable DVD/USB. Boot with it (no installation needed) and see if displays are working.

Thanks for all the suggestions. I'll try them all tonight.
