CPU often pegged at 100%

Running Small Business Server 2003 on a HP xw6000 containing 4 gigs of memory.  CPU is 2.79 gighz.
I run Process Explorer on this pc all the time.  The system information display tells me the CPU is often pegged at 100% yet the memory commit is usually steady at 1.6 GB.  

My question:  

1.)      What can I do to determine what causes the CPU to peg at 100%?  Is it disk usage?  If the commit was at something like 3 gigs then I would suspect lots of swapping to the page file was happening.  I dont think this is the case.

2.)      Im thinking of buying a newer machine.  I dont have lots of money.  What features should the next machine have to reduce the CPU usage?  

3.)      How can I determine if buying a machine with 2 cpus might be useful?  

4.)      What must be done with Small Business Server  to enable it to run on a pc with 2 cpus?

Can you tell from Task Manager which process is using up your CPU? Is it the Anti virus program? I know some software do consume loads of resource when doing re-indexing.

You can buy machine with Duel core or even Quad core - SBS will itself utilitise such automatically. However I don't think it is worthwhile to buy a new machine just for the issue you are having. Installing all the same software on the new machine and this may happen again so I recommend you do find out the source of the problem.
