GUESS WHAT??
iT STARTED DOING IT AGAIN!!
LOLO!!!!
I would do the error check on the disk just to be certain. If the problem starts after the computer warms up, it could indicate a hardware issue and not a software one.
This is what I meant by intermittent problems. Sometimes it worked well for hours and other times it sputtered and slowed to a crawl. I also thought it was software and did multiple restores, virus scans, etc. but it was a couple bad sectors on the hard drive. If you don’t do the error check and lock out the sectors, you can seriously fragment the files on that drive.
