Unexpected reboots

[Ayman Altounji]

Server reboots periodically with the following message:
*****The computer has rebooted from a bugcheck. The
bugcheck was: 0x00000041 (0x00001000, 0x00007c8d,
0x0000035d, 0x00012860). Microsoft Windows NT
[v15.1381]. A full dump was not saved. *******

Processor board was replaced approximately 1 month ago following similar unexpected reboots but error messages relating to non-maskable interrupts:
*********The Compaq System Management Driver has detected that
the system encountered a Non-Maskable Interrupt (NMI)
prior to this boot. The NMI source was:
Uncorrectable memory error, socket 2. ********

This processor board replacement seemed to resolved this problem until the last couple of days when unexpected reboots have returned (approx. twice a day) coupled with a few blue screen "STOPS" siting "Unexpected_kernel_mode_trap" as the reason.

It is also worth noting that the server is running extremely slowly sice the recent reboots. Even simple processes seem to hog processor time.

Any ideas??? Thanks in advance..

Hi, did you replace the memory module in socket two and did you ran any diagnostic; on memory. Hope this will help.
