A few days ago I was using my computer perfectly normally when I started up a game. If it matters, the game that I was playing was "Rust." I have a decent computer with a Radeon 7870 graphics card and can run pretty much every game fine on high settings. All of a sudden, the game got extremely laggy and random chunk of green purple, red, and more started flashing around the screen. It was completely random and I can't think of any specific action that may have triggered it. Navigating my way through the "fog" of the randomly colored pixels, I ALT TABBED and restarted my computer. I turned it back on, Windows 8.1 is loading, and right when it's supposed to hit the login screen, nothing happens. It goes black. Nothing works.
- I don't have a disc.
- Windows 8.1.
- I overclocked my graphics card, Radeon 7870, a week or two before this happened. I'm wondering if this caused all this.
- I can't revert back to a previous state (in the advanced options area when the computer starts up) because it gives me an error and says there was a problem.
- Nothing happens on the black screen. It's completely unresponsive. CTRL + ALT + DELETE doesn't do anything.
PLEASE HELP?! I've looked far and wide all over the internet and I just can't find anything that helps. I've also been trying to figure out a way to un-overclock my graphics card and set it back to default settings, but that seems impossible as well. Any information that you can provide would help me greatly, and I thank you in advance.
