Last week, my computer showed signs of slowing down. Programs, when double-clicked, would take a minute or two to open. Whenever I would go into my hard drive, the cursor would turn into an hourglass and the flashlight icon would appear, indicating that it was looking for my hard drive. And whenever my screen saver would start, the cursor would turn into an hourglass again and then the screen would turn black for a couple of minutes before the screen saver would appear (My screen saver is a My Pictures slideshow). Within the last couple of days, all these symptoms have gotten worse: Sometimes it's minutes before I can get into my hard drive, and a lot of my programs don't come up for a long time -- at least 20 minutes in some cases -- after I have double-clicked on them. I am running Windows XP with Service Pack 2, I have 2 hard drives (C:, 250 GB, and D:, 80 GB), and I have an Intel Celeron processor (2.6 Ghz) with 1.5 GB RAM. I have run Norton Antivirus 2006, Panda Online Software Scan, and Spybot for viruses and spyware and Registry Mechanic and PC Pitstop for performance issues. Nothing seems to have worked. Does anyone have any idea what could be happening here?
