you don't have any screen savers set, or power management features enabled, coorect?

I would start by illiminating screen savers, possibly one could be corrupt.

Power management features might have something to do with it, other than that, it's probably overheating..possibly your video card or CPU if it has a dead fan on it.

"Question 8: Why do I get 30 seconds delay on the first NT bootup blue screen?

Answer:. Each dot is part of the boot-time chkdsk (autochk.exe), and each 3 dots represent one drive so there should be 3* dots. Sometimes if something is wrong with that drive the startup will be delayed. However there is a known problem with NT if your computer has one or more IDE disks and one or more SCSI disks which results in a pause of around 30 seconds. The problem is due to the detection code used by NT and is currently being investigated by Microsoft."

You might want to try a different PSU as well.  Dodgy PSU's cause very strange problems.

I have a rubbish PC at home and with a 300W PSU it was really flaky, took about 6 attempts to get 2000 Pro installed.  Then after putting a 400W PSU in and tried again it been as solid as a rock.
