your hard drive or your motherboard is dying. you will need to find out which by swapping components and testing them. the easiest is to test the drive in another machine.

Recently Ive been having trouble with my computer.. recently windows xp kept locking up and before it would lock up It would make that "ding" sounds you hear when your booting the computer which comes from the harddrive i guess thats the sound it makes when it turns on. When i rebooted i came up with the blue screen saying UNMOUNTABLE_BOOT_DRIVE.. I had no choice but to reinstall xp.. Once i reinstalled It worked fine for 3 days and now its starting to lock up randomly for 5 mins at a time and making "ding" sounds.. Is it time to replace the harddrive? or is there anything else i can do about it
