Try the `top` command on a terminal. It should give you useful information
as to which process is taking up how much of CPU time and memory. It will
also show you your CPU load averages along with memory and swap usage. You
can sort the information on various fields. Press 'h' to have a look at
various options available. You can post the output of `top -b -n1` on the
list if you want people to have a look at it.
Also, try booting in after disabling ACPI using 'acpi=off' as a kernel
option. Defective ACPI (due lack of proper drivers) can cause the kernel
ACPI thread to take up almost 100% CPU making the machine extremely slow.

As people have already suggested, you should think of using a 64 bit
distribution. If that is absolutely not possible, then you can still make
use of all 8GB of RAM by enabling 'HIGHMEM' support in the kernel.

My 2 cents...
HTH.
