The Dimension 4600 appears to be a Socket 478 machine, supporting a single
P4.
I suppose that the OP has a P4 that supports hyperthreading, and somehow it
wasn't detected when Vista was installed. (Was hyperthreading turned on in
the system's BIOS settings? The Dell P4 machines that I see at work
generally have hyperthreading turned off. Whether it's the default, or
whether our IT department turns it off for maximum compatibility, I don't
know.)
There are methods for changing the HAL in XP, but I know of none in Vista.
I don't know what is messed up in the OP's system. I doubt that having no
hyperthreading would make the machine feel slow most of the time. Vista
might run slightly slower than XP, but not greatly so.
Return address scrambled. Replace nkbob with bobkn.
