I'm a dinasaur with little to no technical understanding of computers. I have a dell inspiron desktop computer, and I'm told my harddrive may be dying. computer has died twice in two weeks. Hard drive is less than 1 year old and is 3rd for this tower. utilities and drivers dvd passes all diagnostics on everything. the other guess thrown out was wiring or motherboard as culprit. very tight limited budget and must get best quality I can as cheaply as possible. I basically surf the web, listen to audiobooks constantly, and play pogo games. It's my main intertainment. Anyway I was shopping newegg.com for hard drives and see western digital internal green harddrive 750gb that seems reasonable but listed as bare drive and no idea what that means. Also wondering what tower if I have to go that route might fit the bill for me. help please
