Check your ram modules.Try installing on one ram module.Make sure the cd is in good condition.

Doubtful it is ram in my case.

Installed an old WD wd400bb & installed XP Pro SP2 oem. No problems.

Replaced the WD with a new Seagate 120gb Barracuda, installed XP from the same cd, & I get BSOD with the C000221 Unknown Harware Error message along w/ the filename \systemroot\system32\ntdll.dll. Cannot get beyond it.

Zeroed the Seagate, tried installing XP again, same error.

???
