XP Boot up screen Slow

I’m finding my computer when I bootup staying in the black screen for about 8-10 minutes then when the XP Home page shows up it stays there for a few more minutes then of course it lets me into the login but. Then of course I have the problem that when I open an application it appears to hang… Then even when I open taskmgr it takes a long time to open up. Then when I do finally get in to taskmgr, I end up getting nothing starting up…
Thanks everyone for any assistance..
