Keeps hangs and unable to start the window

Hello,



I had get into this problem now:
When I boot my pc,I keep get random hangs on the booting screen,where all your hardware specs showed up.I just couldn't start my window xp since it hangs Many Many times. sometimes when it hangs on the booting screen,it gives out a fast beep sounds,not,everytime though. Mostly hangs on initialising usb controller and device part(I don't think my usb devices had problem for some reason)When sometime I'm lucky to get my window started,but later it will just hangs and reboot again. Any solution?
