sgt_shultz: Thanks for responding.
During Safe Mode boot I get a Blue Screen that says:
IRQL_NOT_LESS_OR_EQUAL
STOP: 0x0000000A (0xF7B51354, 0x000000FF, 0x00000001, 0x804E5CF6)
Obviously this message is not very helpful. However I did some research on the Microsoft Knowledge Base and this seems to indicate some kind of hardware or device driver malfunction. I sometimes also get a BSOD that says BAD_POOL_CALLER which seems to confirm a device driver problem.
I don't get these BSOD's in normal boot mode which suggests that maybe I am missing a driver. Or maybe there are two sets of drivers and the Safe Mode set did not get updated properly. The Safe Mode boot goes all the way thru the driver list displaying eash name, then delays about 2 seconds, then BSOD.
For now I am just going to live with this problem and hope for the best. But I have a new dual Xeon box that I wan't to convert over to and I don't want to start from scratch. I have already had to reinstall 4 times in the last 4 years and it takes at least 2 months to get the system back to where I need it.
I might try your suggestion of a Repair from the install disk. But now I am running SP2 so I might have to "slipstream" a new install CD with SP2 overlayed on it. Otherwise it might not work either.
Thanks.
