Installed MSI KT4 now system runs like dirt

[Chusher3]

I installed the mobo, about the 30th mobo installation ive done, and i got the dreaded unmountable boot volume, a prior problem, i did a low level format(wrote zeros) then formated the drive for ntfs and im installing windows xp now, it is running slower than the p3500 im typing on right now, its still installing, and it will be for a while. Anything i should check, any suggestions, im running out of options, I had some instability a few weeks ago, so i bought a new cheiftec case and a 420watt ThermalTake smart pure power psu, the stabilty still wasnt all there so i bought a ThermalTake GF4 cooler(copper cooler and ram sinks) and installed them to cool my TI4200 and bought the new KT4 Ultra all from newegg.com.

I am running an AMD 1800+ with 512 Kingston PC2100 ram
I am running at 133mhz bus, nothing overclocked.

Please help, I'm quickly loosing it.

I had some major issues with MSI KT4v and found out from a local vendor that the KT4v has given the a lot of problems, too.
