W2K3 Enterprise Blue Screen

Hi,

W2K3 Enterprise Server running on HP 380 G3 machine suddenly has Blue Screen. With Message IRQL_NOT_LESS_OR_EQUAL. 0xB9793AP4, 0000001B,00000000,804F0743.

I don't upgrade any driver for this machine.
and still searching what caused this.
Please give solution for this.

Thanks

Corrupt Driver Maybe

Memory problems...

 

IRQL 27 (ie x'1B') is the profile timer interrupt. It crashes only if it is hardware problem. The BSOD is not related to sofware problem. The culprit may be faulty CPU, RAM, M/B, PSU or overheat.

 

CPU was my bet too as I have seen that message before on a bad P-IV 3.2 Prescot.

 

I have 13 confirmed case of failure at IRQL 28 (clock level interrupt). 6 is CPU, 4 is RAM, 2 is M/B and 1 is overheat. However I don't have any confirmed case of failure at IRQL 27.
