thanks for the help
i am running on a VPS its supposed to be like a dedicated sever.
http://www.knownhost.com/services/vps.html i have the vpsLtx plan with 256 extra ram on top of what is in the base. i have increased the ram but i still have a high CPU usage.
to my knowledge other sites shouldn't affect my site.
if u suggest i find another host please give suggestions. i have been thinking about it for a while now. but thought it was something on my end. but after lately i am not so sure.
