Default i7, x58, Kernel Power error

Hi everyone,

I'm having an issue with windows 7 64bit where my computer suddenly reboots. I know for a fact I've no viruses. This is a hardware /firmware/driver issue.

i7 920 C0
X58 motherboard
6GB of 1666MHz Mushkin RAM.
Liquid cooled. At load, CPU never exceeds 55c. Idles at 40. Sexy watercooling god damn lol.
PCPower and Cooling 750W
GTX 460 768mb.
1 CPU loop Swiftech MCP655 to an Apogee XT.

This CPU has been OC'd unstably to 4.0GHz, stably to 3.8GHz, on air. I've not pushed the limits on liquid, yet. I took it back down since the summer was hot in uni res and it was making my room way too hot.

These days my computer is rebooting suddenly once a day. PC is under load sometimes, other times it is not. I check event viewer and the only issues I see are:

Error // Eventlog
Audit events have been dropped by the transport. 0

Critical // Kernel - Power
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

Error // Eventlog
The previous system shutdown at 9:16:13 PM on ‎5/‎19/‎2011 was unexpected.

This is AFTER I enabled speedstep and C6. Before this, I got the above errors along with 8 of these:

Error // Kernel-Processor-Power
Performance power management features on processor <0-7> in group 0 are disabled due to a firmware problem. Check with the computer manufacturer for updated firmware.

Has this occurred to anyone else? Any advice?

this post is dead for missing info like motherboard brand and model

first back-up data off HDD

check MB bios versions and apply if needs

Note: the Ram on x58 are place in every other mem slot 1,3,5 not 1,2,3 for 3 sticks of ram

after updating MB bios then start fresh again (Format) use current intel x58 install driver for w7-64 F6 option (use this )

EVGA x58 3X SLi board.

Computer has been running fine, only started rebooting recently (last month, mainly).

I have my RAM in the 1,3,5 positions.

NB hits about mid 70'sC max, stock cooling.

Case is NZXT Tempest - 3 intake fans, 3 exhausts.
