xp opening page freezes up

HELP!! Previously posted in Hardware section yesterday, but no response. I guess it could easily be a "software" question so here it goes again. Surely someone recognizes this. We need help with this ASAP. Thanks!!

We are a small one-computer business, and are about to go "live" where customers can order from us over the internet. We have been working with our ASP on getting this started, meaning downloading .net framework 1.1, a print manager, etc. We shut our computer down every night, and during the week we have no problem the next morning on starting back up. HOWEVER, after being off over the weekend (only one extra stinking day), the XP opening page freezes up (the three little blue cursors go left to right for a few times, then just stop). Here is some more background:

emachine w/ celeron 633
windows XP pro

Needed a second printer, so I installed a second parallel port. As this was running through the wizard and installing, a window tells me that this piece has not passed (or been subjected to, don't quite remember the exact verbage) windows xp logo testing!!??? Continued anyway, and everything seemd to work fine.

As stated, the past two Mondays, I have had to use system restore to get back up and running. Ironically, it seems that I have had to back up to a day before the new port was installed. Could that "logo testing" bit be that much of a problem?? Also, just in case, as I restored this morning, a windows update prompted me. Part of what downloaded was a .net framework 1.1 update. Did it sense something out of whack and maybe it is now fixed??

Problem is, I don't guess that I will know for sure until next Monday. UNLESS, someone here recognizes the problem and can tell me what to do beforehand. Can I post a log or something? Hope I provided enough info. Thanks!!!!
