This is a Dell GX280 optiplex P4 with 512 mg ram running win XP Pro SP2, Novell and Zenworks 6.5. I get a blue screen and then once get PC up msg recovering from serious error. Error code 40000080, parameter1 82cafad0, parameter2 829ddb48, parameter3 f8a68de8, parameter4 00000002. The O/S is from same image I use in all PCs and all work fine but this one. Run all Hardware diagnostics and they all passed fine. What could it be the problem?
