SQL Server is needed to run the NeatReceipts scanner software (see www.neatco.com). I can kill it for testing purposes. VNC is a neat program that lets me open a remote desktop to this machine from another one on my LAN. Again, I can kill that. It's not vital. "Also does it now work ok or not?" Well, it's too soon to tell for sure. All I know is that I was able to run Avira for the first time in normal mode without BSOD'ing, and we are now up for 3 hours and still running. The last windiag I ran before installing new chips clearly showed RAM errors that had not appeared the first two times I ran it. The new RAM may be the difference. So I'm hoping the only problem left is the CD drive, which still does not recognize any data discs or DVD's.
