The bug is your processor. Celeron 2.4GHz is a lemon, chesswise. I bought one
recently at Staples on special sale, a Compaq Presario S4200NX for about $600,
enticed by the 2.4GHz "speed". I only found one non-chess benchmark where the
2.4GHz was reflected. But as far as chess analyis goes with the Chessbase
systems/engines, my tests indicated that it was "effectively" only about 1GHz
relative to earlier processors. Thus, "GHz" really isn't a reliable indicator of
processor speed anymore. You have to consider the processor type and how well it
works with your particular applications - chess, in our case. I took it back to
Staples for a refund within their 14 days allowed time.

I then took the big plunge and bought a $498 Compaq Presario S4020WM from
Walmart with an AMD Athlon XP 2400+ processor running at 2.0GHz. This one works
well with chess software, and it's indeed a true 2.0GHz speed in comparison with
earlier processors. It only had 128MB installed RAM, so adding more memory was
needed to make it perform comfortably. Also I replaced the slow 40G hard drive
with a fast 120G. Now it's a good chess computer system. Incidentally, Walmart
has a 15 day return policy on their computers, which is a good thing because the
first S4020WM I got from them was a lemon. I had to take it back for exchange.
Then the second computer was OK, but the enclosed Compaq 7500 monitor konked out
within a few days. Compaq replaced the monitor so things are OK now. Just be
prepared to take back new computer equipment that doesn't work right.

So, I would suggest that you get an AMD, and forget about Celeron. The older
Celerons were OK, but not the new ones. Until just recently, I was using a
500MHz Celeron W98se computer purchased in 1999, and it was a good machine.
