Hello, I am trying to upgrade my 4850 from 11.5 to 11.9 and every time I update I run into major issues and the only way to get my computer back into working condition is to do a system restore. After I update to 11.9 it will boot to Windows but then after about 45 seconds I'll get a bunch of flashing boxes then the screen goes completely white with lines. There's a link to a picture of it on the bottom of the page. Or the card's fan will get extremely loud and my monitor screen will go black and say "No Signal."
Here is my setup:
AMD Athlon II X3 450
CORSAIR XMS3 4GB (2 x 2GB)
APEVIA ATX-CW500WP4 500W ATX Power Supply
ASRock M3A770DE AM3 AMD 770 ATX AMD Motherboard
XFX HD-485X-ZNFC Radeon HD 4850 1GB 256-bit DDR3 PCI Express 2.0 x16 HDCP Ready CrossFireX
Windows 7 64 bit Ultimate
It feels like I've tried everything. I've updated my BIOS. I've made sure everything is up to date in Windows. I've completely uninstalled anything ATI related and even ran Driver Sweeper then updated and it still has the same issues. I don't get why it works on 11.5 but whenever I try to update it does this. What could be causing it? Thanks for any help.
