i was trying to fix my catalyst not working problem, which caused very slow internet browsing, though it would work fine when i went to geust, so i figured that if i re installed tha ATI it might work but that did not work, i ended up having to look for ATI driver online and downloaded it, after i installed it the screen would go black after i log onto the regular account, but when i log into geust it works fine? cept that no ati has been installed... can anyone fix this? i cant play dota no more
