Help please!

Hi everyone,

I have been having some issues since I upgraded to Windows 10 from 8.1 a couple of months ago, and for some reason never put together the upgrade with the issue.

This is in part due to the fact that it originally only happened when I played League of Legends. Whenever I would load into the game (full screen), both of my monitors would go completely black. I could still hear the sound inside of the game, but was unable to see anything, or do anything (could not alt tab for example). I exhausted support from the LoL support team, and they suggested it could be a hardware issue. I did some more research, and found that some had issues similar to this due to a cpu over heating issue. So I went and got some new cpu heating paste, put it on, and tried it again. It worked for one match, and then the issue started up again. Now it is affecting other programs, and is driving me insane!

I thought it was the driver, so I tried to uninstall all of my drivers, and roll it back, didn't work, so I went back to fully upgraded drivers, still didn't work. Now a friend has told me that it could be the windows 10 free upgrade because the upgrade is very buggy as its effectively a mask and causes a lot of issues. Was really hoping I could get some help with this. Thanks in advance!
