I put together a new computer yesterday for my dad and after a bit of messing around with the RAM (I think one of the sticks is dead), the computer boots up no problem. I proceed to install drivers for the mobo and drivers for the graphics card (it's a Sapphire Radeon HD 6850). The thing is, before installing the card's drivers Windows 7 installed drivers for it on its own and it wasn't running Windows Basic, it was running Windows 7 with its graphics accelerated interface. After I inserted the disc and installed AMD Catalyst from the disc I restarted. First thing I notice upon start up was when I opened a window there were many after images. The computer froze and then the monitor turned black, then it starts working again and I get a notification that Windows recovered from the graphics card's crash. And it happens every. Single. Time. I do ANYTHING. I open a new window, freeze, black, crash. I right-click, same thing. I spent a good 10 minutes trying to get the computer to run in Windows Basic. And of course it fixed the problem, except now the $800 desktop is about as useful as a notebook. So, anyone got any ideas? I tried downloading and installing Catalyst from AMD's website rather than from the disc but the problems still persist. I hope my graphics card isn't FUBAR'd... Here are the specs for this computer: Windows 7 (32-Bit... yeah I know, I gotta upgrade this) AMD Phenom II X6 1090T 3.2GHz Sapphire Radeon HD 6850 4GB of RAM DDR3 1333MHz (Its supposed to be 8 but I think one of them is busted, also only 3.5gb is available on 32-bit Windows 7). I also wonder if its the power supply... which is strange, as I have the same one for my computer but other than the fact that I'm running a 3.0GHz CPU, the graphics card uses more power (this is card in question). My power supply is this.
