Hi, For some reason, when I click on the Catalyst control centre icon, it doesn't appear. This is annoying as I cant get into my monitor settings or anything and have to use the Windows (crap) ones. Tried re-installing all the ati drivers, .NET framework- even have a new x1900xtx graphics card (as my x850xt had a dvi problem, which I thought might be the cause) and it still doesn't work. System specs: ASUS A8R32-MVP Deluxe, 1GB Kingston RAM, Radeon x1900xtx, AMD Athlon X2 3800. Also, when I had my x850xt, and this problem arose, ATI TOOL suddenly didnt recognise the card for some reason. The default clocks were wrong on opening and it just didnt work. The only thing I can think of is deleting a registry entry with Crap Cleaner, which I might have done by accident- although have installed all drivers and stuff loads since that happened- so I really have no idea. Thanks for reading, and any help is appreciated.
