Ive just installed a gig of ram a x800xl gaphics card and put a new psu in and sometimes when I start windows (xp) it hangs while things come on. Its not that long (can be anywhere up to 2 mins) but if I try to do anything it freezes til its finished. Any ideas what this could be? Dont get me wrong its not that big of a deal but I suspect this shouldnt be happening. Somebody suggested I reboot the pc because of the new ram, is this necessary? Thanks for any help.
