Computer closed down with "Fatal System Error" with first restart!!

I just installed the free version of AVG on a Windows 2000 Professional. Upon finishing, I attmpted to check RoadRunner mail and received an error message that the server could not be connected. So, I rebooted and received an error message on a "blue screen of death" stating "STOP: c0000021a (Fatal System Error) Logon process system terminated unexpectedly with a status number of 0x00000080; and two more hex numbers of zeros. What say you????
