For about a month now, my computer has been taking longer and longer to start. When I turn it on, it goes to the loading screen and completely freezes without the loading bar moving. After about a half an hour, the loading bar will finally appear and start moving, then freeze again. It is usually still another ten minutes or so from the second freeze before XP completely starts up.
It was at its very worst this morning when I turned it on and it took almost an hour to load. When it finally was on, I had to go somewhere, and when I came back and tried to turn it off of safe mode, it froze and I had to restart again. I was so mad I just started it in safe mode, and that's how it is right now.
I have no idea what to do. I tried running msconfig and turning off almost all the programs that automatically start when XP boots, but it didn't work. I also tried getting a program called Bootvis (I think) to trace what was causing so much slow down in the start up, and when the computer finally loaded up all the way and I thought I could see what was taking it so long, bootvis crashed and lost the statistics from the start up.
What else can I do?
