Hi! I am having a huge problem with a brand new computer that has been running perfectly well. It is a Dell XPS and is about 4 months old. The OS is Windows XP. My friends came over and supposedly download dell drivers to a flash drive to bring to my other friends laptop. My computer is now choc full of problems. I can run various applications, but everything is slower. I managed to view Task Manager twice at random times, but it otherwise never opens, along with: Every application in "Control Panel", System Restore, Regedit, right clicking "properties" on the desktop or on My Computer in the start menu...I have not even tried others because it seems obvious they will not work. I cannot open versions of applications I already had downloaded, but can run any newly downloaded apps like Ad Aware and Hijackthis. The old versions do not open at all just like everything else. When I did view Task Manager, it showed I was running almost 20 extra processes then I had before my friends tampered with the PC. I have run Hijackthis and their analyzing showed no problems whatsoever. Booting in safe mode mirrors all of these things and is not helpful in any way. Can anyone help me? I have not even heard of anything like this happening to anyone. My AIM works fine, IE works fine, Windows Media Player and my full 70 Gigs of music are all in tact. But almost everything else is not accessible and seems to have vanished. Also, these icons have transformed to look pixelated and large like old Dell desktops. From the crisp XP versions, I now have these large icons and crappy pixelations on my desktop icons (not all of them, though) and the start menu icons.
