Problem description: Built a gaming PC about 3-4 years ago. It will run fine for weeks. Eventually when I turn my PC on it was show "no display." I cannot get past this and hard rebooting does nothing. Once in a while if I let it sit and come back to it it works just fine. However, this last time it did not work. If I restore Windows it will work again for a few weeks. The computer is booting just not showing a display.

Imgur cut off my images but you can see the LED issue here: http://imgur.com/a/XqUrn

What's weird is one of the LED on my GTX 780Ti will only be half lit. Not sure if this is an indicator and I cannot find information as to what these lights represent or if they're just for fun. It is odd and may be an issue though.

Attempted fixes: Using different display ports, running computer with just one video card or the other.

Recent changes: No. This has been going on since July and I took a break from PC gaming for half a year due to work and not wanting to deal with this issue.

I'd try these steps in this order:

1. I'd use DDU https://www.wagnardmobile.com/?q=display-driver-uninstaller-ddu- and then reinstall the latest video card drivers.

2. If that doesn't work I'd make sure you're on the latest motherboard BIOS.

3. Try a different monitor and/or video cables.

4. Try a different video card.
