Sounds like it may be trying to re-run or complete the recovery process. You may want to try re-doing the recovery.
Or, you might check out the startup programs in msconfig. The recovery may have configured alot of startup programs you don't want or need. Also, a defrag may configure the placement of startup programs for a more efficient startup.
You might also consider going to MS update and getting SP2.
Hope this stuff is helpful.
I had a virus that pretty much shut down my HP compaq nc6000 laptop (running Windows XP sp1). I had pcillin virus scan, but it did not fix the problem, so I used my recovery cd's, which took approx 24 hours to install. The laptop seems to operate ok except for the initial boot up. The microsoft screen appears, then it goes to a dark screen and after a couple of minutes (3-4), a long ''barcode'' (what it looks like) appears at the bottom of the screen and after several more minutes(3-5), the Windows XP screen appears and completes the boot. Any assistance would be appreciated!
