I just got a Asus Radeon 6450 today to upgrade from my intergrated Nvidia 650se. I have major problems! I disabled the onboard graphics from the pc, then shut off the pc. I put the card in and installed the software on the disc it came with. I rebooted and then this is where problems started happening. I put my password in and was on the home screen. I was moving my mouse around when it stopped and froze. Now every time my pc starts up it does the same thing over and over again. I would really like some help as soon as I can get it. I am currently running in safe mode. I tried uninstalling the card and reinstalling the drivers but that didn't work. Any help soon would be appreciated.
