This started happening yesterday. I entered a game (EU4) and about 2 minutes after playing my monitor black screened and said no signal. The sound was still playing, but I could not do anything so I turned my computer off using the button. I also tried with CS:GO and the same issue occurred. I suspected it was a GPU overheating problem so I downloaded Furmark. I tested it and it ran to 87C before I exited. Nothing happened until my GPU hit about 60C and then the same thing happened. Also, I can watch YouTube videos and Netflix movies/tv shows with no issues. Please help, as I have no clue how to fix it.
Thanks ahead of time.

Specs:
Intel Core i3 3.3Ghz
XFX Radeon HD 7850
12GB RAM
500w Corsair PSU

I just tried running it and it seemed to have deleted my drivers as it rebooted and the resolution was low. I tried opening Chrome to get to AMD's website to download new ones but when Chrome was opening I blackscreened. I'm sending this on my phone.
Edit: Just tried rebooting and it rebooted to the desktop but it is still low resolution (because I haven't installed drivers). I waited on the desktop and Windows started downloading the drivers. About halfway through Windows installing the drivers it blackscreened. Will I be able to download the drivers?

The low resolution is due to there being no driver at all.. Try downloading the drivers in safe mode. Then when its done. Reboot, then install the drivers in normal mode. EDIT: Oh I didnt read the part where you said you were installing them.. Are you trying to install them in safe mode?

No it rebooted after DDU was done and it booted out of safe mode. Then I tried to download them manually but it blackscreened and so I let Windows try and download the drivers and it blackscreened again. Thanks for the help btw

Try fully downloading the driver in safe mode NOT install. Download, exit, do a normal boot back into the OS. Dont open any programs or anything, then just try and install the driver.

Now it is just launching into startup repair even when I say not to. It asked me last night if I wanted to do startup repair and I did but I read that it can take days to get out of the screen and so I did a hard shut down and it worked last night. Should I just stay in startup repair?

Hmm. I've never heard of the startup repair taking days? I guess that depends on how severe it is. But if it's just really a driver issue it shouldnt be that bad. Since you have Windows 8.. I'd just let it do its thing and see what happens when it's done.

I have Windows 7 but I guess I'll just let it go and see what happens. I'll wait a couple hours before I do anything but I at least need to get back to where I started (everything else works except gaming). If and when it finishes I'll let you know where I'm at from there.

It finished the startup repair about a half hour ago. I am now trying to boot in safe mode to download the drivers but it seems to keep getting stuck at the please wait screen (it says loading Windows files at the top and please wait on the bottom). Sorry for asking all of these questions but I have never done this before so I don't know what to do.
Edit: It just successfully booted into safe mode. I'm going to try and download the drivers.

Sorry for posting so much but I installed the driver and the resolution came back (as expected). I tried playing CS:GO and it still blackscreened after playing for about 5 minutes. Thanks for the help so far.
Edit: I just was using the internet (I was actually researching the issue) and I had 10+ tabs open (I didn't realize I had that many). Sometimes I have a lot of tabs open and have no issues so would this maybe be an overheating problem? Before it black screened I saw a video and it said to underclock the video card by 15%. I was also thinking of cleaning out the dust from my case. Should I do these?
