Hello all, I'm having a problem getting my rig to boot. My specs are as noted on my profile. I'm running Windows 7 Ultimate x64 and no matter which Catalyst Drivers I install they all cause my computer to hang on boot. What happens is WIndows is going through the normal boot process, the 4 spheres float around the screen and form the Microsoft logo, the logo pulses, then just when it's about to load the whole process stops and hangs. I can tell it's about to load because when my computer boots up properly just before the login screen pops up my sound flickers for a second and the LEDs on my keyboard go out then come back. I know it's the driver because as soon as I go into safe mode and uninstall the drivers (through Device Manager) and run Driver Sweeper until it finds nothing then Windows boots into normal mode with no problem at all. What I've tried so far: Made sure both cards are seated correctly on the motherboard Express Uninstall from Catalyst Control Panel Uninstaller Driver Sweeper AMD Catalyst Uninstall Utility Tried, from clean (no hits in driver sweeper), the following drivers: 13.2 Beta 13.1 12.10 12.8 My cards are completely stock, no OCing at all and using stock cooling What I'm going to try: I just read about ATIman and the difference between driver sweeper and driver fusion. I'm going to try ATIman and driver fusion in conjunction with driver sweeper and see if that fixes anything. Anyone have any suggestions? Thanks in advance! Additional: Sometimes, with the driver installed, after the LEDs on my keyboard and sound flickers neither come back on, sometimes they do and stay on but it always sits there at the Starting Windows screen.
