Sounds like it's the hard drive that's going bad. Computer locking up, or taking an extremely long time, during the ide auto-detect process. Unplug all ide cables from the motherboard, turn the computer on, and see if you can then access the cmos setup. If you can access the setup, then it's either the hard drive or cdrom that's bad. If not (and let's hope this is the case), then try to get a hold of different memory sticks to test.
