Re: Possibly hard drive help needed..
Do you see any BIOS screen at all? Although, with this model of Dell, it may be the case where the hard drive will keep the computer from booting. These types of devices can go bad, and cause problems. I have seen a hard drive keep a computer from booting before. Locate the hard drive- I'm not familure with that model- and pull it out. Common places for the hard drives are in a slide in unit on the side, front, or the worst, under the keyboard. If you can pull the hard drive, and get a BIOS screen every reboot, it is probably the hard drive.
