Win XP machine with SP 2 installed suddenly takes 7 minutes to boot. Using msconfig to boot stripped down doesn't solve it. Turning off indexing doesn't solve it. Defragged disk to 46% used doesn't solve it. Whole thing started when I tried to install a 2nd 250 GB drive to go with 45 GB boot drive. When I added the 2nd 250 GB drive system would go through logo screen and then go black and stay that way. Now it does the same thing with just the 45 GB drive installed. Both 250 GB drives are identical Maxtors and 1st has worked fine for months after using big-drive program to use 48 bit addressing.
example of sequence:
2:26:30 hit restart
2:27:02 finishes saving settings
2:27:40 Logo appears
2:31:23 Logo disappears - screen goes black
2:32:09 Start restoring personal settings
2:33:15 restart complete with network
