BSOD loop

I had already read that, so what are your assumptions in this case?,

Like you, I think the HD. But, it could be other things too. It is always better to identify the problem rather than randomly replacing things, that can be expensive. Been there, done that. If you can run the diagnostics again, but select customized tests and test just 1 item at a time you may be able to identify the problem. I would start with the hard drive. Dell usually does not provide installation disks. If you replace the HD, you are going to have to find a way to reinstall the OS. That can be done if you know someone with the same version of the OS that is on your Dell.

You will also need the drivers disk, or better go to Dell's website and download the drivers you need. They will be more up to date than the ones on the disk.

Well he has already ran diagnostic on the hard drive and it blue screened, and it came with a disk to reinstall the operating system.

Be sure. I have a Dell that came with a disk that says installation disk. It is actually a repair disk. Dell usually has a recovery partition on the HD to reinstall the OS. Just for a try, tell them to start the computer and tap F2 on startup. That may get you into the recovery partition if you have one, but if the disk is gone it really won't help much.

I have already used the disk to reinstall the operating system, but here is the diagnostic results

Drive 0: WDC WD3200K-75PFB0- Pass
Drive 1: SONY DVD-ROM DDU1615S - Diagnostics not supported
Drive 2: No Device
Drive 3: No device
Drive 4: TSSTCORP DVD+/-RW TS-H553A - Diagnostics not supported
Drive 5 No device

According to that it is not the hard drive. Put the disk in. When you get to the 2nd or 3rd screen, select repair my computer. try those options and see what happens. See if this tutorial will help.

If you have a system image try that or perhaps a restore point. Maybe something got downloaded that messed the system up.

I have already said it just says loading files and then it goes right to the blue screen it does not go any further than that it is just a loop and refuses to go anywhere when the hard drive is required to run.

Are you referring to booting the system from HD or booting from the Installation CD. I was talking about running the repair from the CD.

Both do not work either way, the cd will run until it has to access the hard drive then it blue screens.
