I have had this problem in the past but it doesnt happen all the time, maybe 1 in 7 cleanings. The problem is, I uninstall my video drivers (in the past I have been using an nVida card) and then run DC in safemode. After running DC, I can no longer install any drivers for the card. It is just seen as a standard VGA and wont even let me do the have disk method. Last night, I just got my new motherboard and 4870 x2 so had to do a clean install. Stupidly, I assumed the drivers on this brand new card line would be even close to being up-to-date. Sadly, after installing the drivers I realized it installed v8.52. Needless to say I promptly uninstalled the drivers, loaded in safemode, cleared everything ATI using DC, reloaded Windows and tried to install the 8.7 drivers I downloaded from the ATI website. However, all they do is install the install manager, nothing else. I can't have disk or anything. In the past, I have had this problem on XP 32, 64, Vista Premium 32, 64, Vista Ultimate 32 and 64. Currently I am on Ultimate 64. Any suggestions here? I dont know if this is DC, a randow Windows bug or just bad luck. Thanks!
