I recently got an error when I booted up telling me that Windows couldn't start because a file was missing or corrupted, and that I should use my Windows disk to do a repair. When I boot from the Windows disk and try to do a repair installation, my computer shuts down before I am able to make repairs. Furthermore, I am unable to detect my hard drive through my BIOS. I tried a different IDE cable from another computer to see if that was the problem, and then tried plugging in a different hard drive, but nothing showed up. After rebooting a few times, now my monitor isn't turning on, and the machine shuts down automatically a short time after turning on.
I have an older computer that I can switch parts out with, but I'm not sure where I should start. I can't get into my OS, so it looks like a hardware problem, but I'm not sure how to know if it's the motherboard, processor, power supply, or something else...
