Windows XP: When I activate internet explorer, more often than not, nothing happens. On Windows Task Manager, nothing will be listed under applications, though, under processes, there will be an iexplorer.exe for every time I've tried to activate explorer, usually with a memory usage stuck at about 11,000K. I've scanned my computer for viruses and have found nothing. Oddly enough, one way around the problem is to already have Windows Task Manager up and running when I activate explorer, though this only works about 75% of the time. If I don't do that, explorer only opens about 25% of the time. On a probably related note, when I shut down the computer, I've noticed a blinking effect on the desktop, as though numerous hidden programs were being shut down (these might just be the stalled explorers). If anyone can help, it would be greatly appreciated.
