So basically, I've just been given a second-hand motherboard that came with a 10GB harddrive and a stick of 512MB RAM. The reason I got it was because it wasn't running.
I took the RAM off it and replaced it with my own 512MB stick. Once I had put on my own video card, DVD-ROM, and the aforementioned RAM, it boots fine, and can run with the 10GB harddrive with absolutely no issues whatsoever.
However, if I hook up the 80GB harddrive that was on my oiginal rig, it boots right up until it starts the Windows logo loading screen, at which point it blue screens and then immediately reboots before I can even get the chance to read the bluescreen error code!
I've tried booting from a Windows CD with both harddrives plugged in separately, but it comes up with an error even then! (STOP: c0000221 Unknown Hard Error: \systemroot\system32\ntdll.dll)
If I try hooking up both harddrives at the same time (on the same ribbon), the BIOS is only able to detect the 10GB harddrive, and then it won't boot up at all.
If anyone can help me that would be awesome because I really don't want to have to run off a 10GB harddrive... Thanks so much everyone.
Here are some stats, if they're necessary:
Motherboard: ASUS P4S800-MX
CPU: Intel Celeron 2.4GHz
10GB harddrive: Fujitsu MPD3108AT
