Terrible Computer Problems

I don't know what caused this, and I don't know what the problem is. I can't seem to find the solution to this but I will be as detailed as possible on what the hell is going on. So let me explain, this may take a while.

 

 

       Recently, my GTX 750 broke and I needed a new card quickly or else my sanity of not going on my computer would kick in, since I already had an APU, my thought was to just buy another AMD card so I can stay full AMD rather with an NVIDIA card. So I bought an R7 260x, slapped it in there and everything worked as it should, installed the drivers and boom, back to 140fps on csgo, played some Alan Wake and boom everything went as planned. Three days passed and my webcam came in the mail. Neat! So I plugged it in, downloaded the drivers and worked fine, then realized that my harddrive was getting a little full so I decided to uninstall a few games like BF4 (Games barely functions I don't know why I decided to get the free week of gameplay thing) few other things and then I realized that I didn't uninstall my Nvidia stuff, there were like four of the icons there so I was like BAI BAI. Uninstalled all of them. Continuing to do so, something needed a restart (I think it was for my webcam) so I did. After the "Windows is starting" thing all I had was a black screen, I was like OH F WHAT DID I JUST DO. I restarted the computer and then realized that every time I started the computer there would be a slight gggrriiiinnn sound for half a second after five seconds when I turn on the computer. I thought my harddrive was at the end of the life span because it wouldn't read anything after the Windows is starting screen. Well at least i think it's not reading anything because the HDD led isn't flickering or anything.

        So I moved the hard drive down to the bottom of my case to the HDD slots or whatever you call them and after about like 5 restarts I got into windows, I didn't bother putting in my password I just thought THANK GOD. Turned it off, put my computer back together, and what do you know, it's back to black screen. I just thought to myself WTH is going on!? Unplugging and putting back the graphics card I thought it could do something and using the inigrated graphics in my APU and still nothing, put the graphics card back in, booted into windows. Nice. Atleast I thought it would. When I go to my desktop, I have the Windows basic theme or at least i think it's called that, it looks something like this:

Like the blue bar on top when I use chrome is there and the bottom is also blue. Like power saver mode when using a laptop. Not only that, I would get short horizontal flickering lines for the first twenty seconds and it would stop. They're very small but I can notice them and I'm really scared that I have a broken graphics card. I couldn't figure out how to put it back to it's original theme. Next thing I knew, I couldn't play a single game. Here's what would happend when I would play Alan Wake:

When I would load up the witcher 2 I would get a black screen and the cursor just becomes a white + sign. I would hit the windows key and It would show up like it's nothing. As if I just open a blank screen rather than a game. Same thing for Torchlight II.

 

Guys please tell me what's going on! I don't want to lose this computer! WTH is it the HDD the graphics card!? WHAT?

To add in one more thing, when I would connect a second monitor, it would go back to the black screen. I can only have one display at a time.

So far what I gathered is you might have a corrupt driver somewhere. Before you installed the new drivers, did you remember to make sure to uninstall ALL of the nvidia drivers first? That could cause a major problem like what is going on. The next thing it could possibly is Viruses and/or Malware. Go into device manager and see if there are any devices with the Yellow triangle. 

I just figured out the problem. I reinstalled the drivers, and everyhting worked fine. So yeah, pretty much what you just said. Thanks for the concern though!

This is a great tool to run to clean a system of leftover gpu driver junk that can cause a multitude of issues.

Especially when switching out between nvidia & amd cards.
