The first massage was only reported once but the second massage was viewed several times.
 Testes tried by our Engineers

•	First we suspected in the Microsoft NT installation so will formatted the NT system partition and reinstalled the software.
The server still rebooted automatically while using any application, and randomly  noting the second massage error faulty.

•	Hence we suspected in the video card because NT version 4 was not detecting the proper driver for the on board card and was not indicated in the NT Hardware compatibility list.
So we disabled the onboard card thorough the jumper and installed a EISA Compaq Qvision video card
which is listed in the Hardware compatibility list.
The sever still shown the same error symptoms, rebooting automatically while using any application.

No further testes where done, the server is in presently in a non operational state , so we would appreciate your assistance . Thank you.

Best regards
