Thanks Allan for your help.
This computer starts in safe mode and takes about 2 minutes to the desktop screen.
I tried it a few times to see if there was any changes in the safe mode startup. Not so.
I don't know if that's a good thing or not. I have rarely started in safe mode.
At least it was consistent.
One thing did occur though on a restart in ordinary mode, that was, the computer cycled through the restart 3 to 4 times before settling down
to useable/desktop.
However there after, the computer has started in one cycle since. So I don't know what that was about?
I picked up another 1 gig of ram and inserted it, so now this computer is running with 3 Gig of ram. Although that doesn't seem to have improved its speed or useability at all.
Another thing that I have tried, is to clean all the dust from inside the case, the fans, the thermal sink & any other area of interest, added a 1 gig ram stick, (after reseating the others one by one & testing the performance and stalling issues).
I removed the chip, cleaned it & re-administered a new cover or thermal grease, replaced all and while I was at it added a second CD, Dual layer burner. (Because it was there). ( I don't know if that was a smart thing to do or not yet, but the case was fully disassembled at the time & that's the best time to instal a burner).
All in all, there has now been an improvement in the startup procedure and it doesnt seem to be hanging any more, but the computer still takes a long time to open windows of different sorts, web browser, programs, windows media player, office/word. I would have thought the addition of an extra 1 Gig of ram would have improved it overall.
Allan, I will try the msconfig procedure you suggested and follow through with that next.
I appreciate too Superdave's suggestion and it may just speed up the process of going through things one by one. Perhaps even give me a bit of an idea where to look for any conflicts but I'll do it all by the numbers so I have a clear understanding of what I am doing. After all I have the time on my hands now that I'm not working for a while. Save for the fact that its nearly Christmas & everyone will be busy stimulating their respective economies for a while.
