If the drive isn't spinning, then it's probably not getting power to the drive. Because the cable connectors between HDD and motherboard can fail, have you tried replacing the connection cable?

And because that computer is probably 4 or 5 years old, yes, it could be a motherboard issue. Have you checked for bulging or leaking capacitors on the board?

Plus, which operating system are you attempting to install and how? Are you using the recovery discs from Dell or possibly a system image you created? Or are you using something else? Ideally, try loading the original factory OS and files on the disk.

Hope this helps.

does the HDD have a jumper placement listed on it?

In reply to: Dell pc will not recognize hdd

No IDE ports on that motherboard, only SATA. Are the drives also SATA, or using an IDE drive with adapter? What I don't understand is how it starts to install windows but then fails. Does the drive move, or it's indicator light on the case flash, when you are doing an install?

To test if the motherboard will boot to any "installed" OS, then boot instead to a DVD with Mint Linux burned to it, or any bootable DVD with a file manager will work to see if the HDD can be accessed. Since the installation DVD already boots, that would mean the SATA ports are probably OK and the HDD should work if several have been tried. If the computer suddenly shuts off and then reboots, this would instead indicate a PSU dropping out or since this is older computer, more like the CPU is quickly overheating and needs new thermal paste between it and the heatsink/fan.

Boot into the BIOS, go to the temperature section and just let it sit there for a while and watch the temps.
