it's pretty weird...when i go to sites and scroll the screen is all wavy...i cant run any games because there is a directx file missing i think. when i try to install directx it doesnt even really do anything....it's worked fine since today...in my display panel i have no tabs up at the top (you cant see them) but when you click around in the area the different tabs just pop up...my resolution sometimes changes randomly from 1280x1024 to 640...it's getting pretty crazy and annoying...i was thinking about just completely reinstalling windows and starting over...but i was wondering how i could uninstall directx completely and then reinstall it so i have a fresh one with no missing files...please help..this is an x800xl radeon...dfi ultra-d nf4 mobo...if you need more specs tell me..
