Hey all.... I'm new to this forum, but I'm not new to computers or fixing problems, but I've come across one that I can't seem to figure out: I'm running Windows XP Media Center on an HP Pavilion laptop. Basically, upon startup, the start menu, quicklaunch, and taskbar all freeze, and I can't use them... I can access the start menu using keyboard shortcuts, but only momentarily before it disappears. I am able to click things on the desktop, but once I open a program or window, whatever I have open de-selects itself, and I have use Alt+Tab to get it back. This seems to be the most telling problem: whenever I open a window (IE, Firefox, or even a Windows window (my documents, etc.)), after a few seconds it automatically goes back to whatever previous screen I had open.... as if I hit the "Back" buton". So it let's me get nothing done. All this still happens when in Safe Mode. I've updated and run all sorts of programs, which makes me believe this might not be adware, spyware, malware or necessarily a virus or trojan. I've run Norton Antivirus, Sybot, Adaware Pro, CWShredder, Windows Defender, AVG Spyware and AntiVirus, online Bitdefender. They've found a few minor problems (a little spyware and a minor virus or trojan), and fixed/deleted them, to the point where now when i run them they find no viruses or anything, but still the problems persist. I have all the recent Windows Updates, so I'm lost. (Note: I know running the different antivirus programs can cause conflicts, so I haven't been running all these at the same time.) Can anybody help?
