Here's my issue so my computer was going well until two days ago. I used to have 2 6750 graphics cards and I decided to upgrade to a sapphire 7970 ghz. So I was having trouble with it going black screen. I figured out that (I had overclocked it a little) it did have enough power to overclock it. So today I was playing games then I decided to run the Radeon auto detect drivers updater. And it found new drives so I let it upgrade then it said failed but came up on my screen a restart was required. So I did and now my computer is stuck on the motherboard loading screen and is making a long beeping noise.
