Windows 10 Black screen after logging in

Hey, I just attempted to install Windows 10 on my new PC. However, it appears there's an issue..

During the upgrade process, the screen went blank @ 75% and didn't come back. There was active HDD activity, so I waited until it stopped before restarting the PC.

Upon restarting the PC, everything went fine and I got the "Hi" messages and so on. After that, the screen went black again and didn't come back.

After waiting, I forced-shutdown the PC and turned it back on. Windows logo appeared and everything seemed fine. Login screen appeared and I could login. After that, the cursor froze and the screen immediately turned black - and it stays that way. What's wrong?

NOTE: This PC has no integrated graphics

Specs:

AMD Athlon 860k processor @ 3.7GHz
Nvidia Geforce GTX 750Ti 2GB (MSI)
1TB HDD
8GB DDR3 RAM

I'm currently using a secondary PC and may have to go back to Windows 7, but I can't seem to interact quick enough to get to the option that allows you to revert. It freezes and goes black before I can :S

I tried tapping F8 on boot but nothing happens, it goes straight to Windows logo.

Any ideas?

Nope. I had to revert back to Windows 7.

Everything loaded fine to start with. Log in screen appears, and I'm even able to log in as normal and see the desktop. But after a while, the cursor will freeze and everything goes black. Sometimes the cursor stays there, and other times it's non-existent.

I think it's a GPU problem. My system does not have an integrated graphics card, so it's obviously trying to use the graphics driver already on my system (which probably isn't compatible). I don't get this issue on Windows 7, so it's clearly a driver issue.

I'm not sure how to workaround this though considering my system doesn't have integrated graphics.
