Random and frequent freezes

XP pro, MSI K7t Turbo 6330 Mobo with Via chipset.
Please look at the following picture:

I think the freezes are being caused by faulty capacitors, do you think I am
on the right track? There is nothing showing in Event Viewer. The freezes
are: Computer stops responding to either mouse or keyboard, I lose all work
I am working on, and a reset is the only way to get it started again. No
error messages. This happens several times a day. It started when I
reinstalled XP so I thought it was a configuration problem but now I'm not
so sure.

what do you think? If these capacitors are shot, can they be replaced or am
I up for a new mobo? <gulp>
