John: Thank you, for your very quick reply! I know you are extremely
knowledgeable. Much appreciated. If I buy a new motherboard, it will
go into a new case, with a new CPU and 2 GB RAM (max is 4 GB).  The
PSU in this Dell Dimension 2400 is only 200 or 250 watts, and I
suspect that may be part of the problem. Barely adequate, as you
wrote. The new case I will buy has a 450 watt PSU as I recall.
Something else I hate about this Dell Dimension 2400 box, and at least
one other box we have, is there is no Reset switch on the Front Panel.
I will get a case that has a Reset switch on it.

I will ask about a g33 based motherboard, and a low end Core 2 chip,
when I go back to the store, with this Dell Dimension 2400, for the
mobo guy to see if he can fix it. He said he can also look at the PSU.
I will wait until after New Years Day, to take it in, so they will be
open and hopefully very sober....

Thank you again and Happy New Year!  Lanny
