Right get this, after the computer was working fine i turn it off one day, the next i turn it on and boom i get 2 OS choices which are : Windows XP Home edition (bootscreen), Windows XP Home edition. an di have only loaded up one OS!, okay now it goes to a wierd BLUE SCREEN sayin i have a problem with UNMOUNTABLE_BOOT_VOLUME. so i have tried safe mode, it doesnt work, i have tried putting my xp CD (which is held on a DELL CD) nope does not work. So how am i suppose to do this? somehow i made my way to diagnostics thing by pressing F2 or F12 and i ran this program which could determine if i could boot my OS, and i got a couple of errors. Could something inside the computer may of come loose, because i do have this strand of a couple of grey wires connecting to nothing. also the computer has been moved about so. Please help, i was going to reinstall the whole thing but how is that possible?
