Hello, I just installed a Radeon R7 250, and It worked for a couple of minutes. But then I updated the drivers (I had the apu drivers installed) and now it won't load any games. I can't even web browse. It was crashing with vertical lines, until I tried messing with the drivers, but now it just goes black and restarts my computer. I tried installing the previous drivers I had working to no avail, and even tried the supplied drivers that came on the disc. Any help would be greatly appreciated!
