Hello all,
I'm running Windows 7 Ultimate 64-bit on a machine with an AMD Phenom II X6 3.2ghz process, 2tb hard drive, 16gb DDR3 RAM, and a 1000w Kingwin modular PSU.
After my old card died, I was forced to install a new card without having the opportunity to uninstall the old drivers. The old card was a Radeon HD 5670, and the new one is a HD 7850 4GB manufactured by HIS. Windows did it's thing, automatically installing the new drivers, and not even a minute after, the screen wigged out and froze up.
I did a hard reboot of the machine, and then Windows wouldn't load at all. It freezes on the "Starting Windows" screen, forcing me to yet again do a hard reboot.
I CAN start safe mode just fine. I already ran CCleaner AND Driver Fusion (the successor to Driver Sweeper) to clean everything with an ATI signature off my machine. I try to uninstall Catalyst, but it will not allow me to uninstall it in safe mode because the drivers in question are not loaded.
When I do this, Windows WILL boot with basic VGA drivers. But when I install the new drivers and reboot, I once again get locked on the "Starting Windows" screen, forcing me to start the process over. I have tried installing the drivers from the CD, tried installing three different version of the drivers from the ATI website, and tried installing the drivers manually through the device manager, all with the same result.
Beyond that, I'm not having any real issues. Everything else during the hardware installation went fine so far as I can tell. My power source is sufficient, my connectors are all correct and secure, and everything is compatible. So I've more or less ruled out hardware troubles at this point. I'm almost certain it is the drivers, but I don't know what to do.
With nothing but the barebones VGA controller installed, I can do most things, like watch videos, browse the Internet, all without graphical errors. However, I do not have access to more advanced features like multimonitor control, resolution management, etc.
Please help. I've tried everything I can think of. My gut tells me this is probably something simple I'm overlooking, but I really could use some other perspectives.
