Hello there, I've been looking all over the internet for a solution to this problem but no one seems to be having the same issue as me
Anyway, a couple of weeks ago I went through a difficult time where I had to wipe my hard drive and reinstall Windows (7 x64, if you were wondering). Everything was going great until I noticed that when I rebooted my computer, my second monitor wouldn't display anything. This was pretty strange as it was working just fine right before I did the whole wipe/reinstall thing.
I run my primary monitor off of my graphics card, and my secondary one off of the onboard gpu on my ASUS P8Z77-V motherboard. I've rebooted the computer multiple times, enabled the multiple monitor setting in the BIOS, and updated my drivers. HOWEVER, my Device Manager is showing that my onboard graphics (Intel® HD) has an error: "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)". If I right click on the device and say "Update Drivers", it tells me that the drivers are up to date.
If I uninstall and reinstall the drivers then reboot, the display pops up on the secondary monitor for a few seconds then switches back to the primary one. When I look at the Device Manager afterwards it tells me that my onboard graphics does NOT have an error, but that changes were made and I have to reboot for them to come into effect. Once I reboot, we're back to square one. The Device Manager tells me that the drivers can't be loaded.
I'm at my wit's end on this one. Any ideas?
