Shutting down every hour

I'd run MemTest86+ over night and see if it reports any error. If it does, you know its the RAM most likely.

Cannot run this over night pc crashes each hour.

I have checked 3/4 Ram sticks by removing them one at a time so far pc continues to crash each hour...last one being tested now.

Each ram stick pulled one at a time....computer continues to lock up each hour.
Maybe its of the GPU's. I'll pull one out and test each to eliminate that.

[Hun]

I have removed and tested each gpu still locks up, removed CD rom drive still locked up, running out of hardware to eliminate.

Maybe flash Bios? its ver 1.0

Read something about uping voltage on northbridge? not sure how to do that or what it would do.

Push comes to shove I'll have to consider replacing MB. This is wearing me out.

What psu are you using?

What psu are you using?

Seasonic 750 Gold, it has already been removed replaced and the problem persisted.

the strange thing is that it is doing it every hour on the hour. i have fixed some similar problems as well with a bios update, but they were hibernate/sleep problems. do you have hibernate/sleep enabled on your power options? if so i would turn it off, and see if that changes anything. next i would turn on event viewer and see if it gives you any clue to the problem. if it points to a file or background services program, refer back to my earlier post about how to diag.

good luck

This is a long shot here.

The PSU is not the problem.
Pc shuts down every hour.
Reinstalled Windows.
Reverted to previous Catalyst drivers.
SSD is main drive.
Rest is on E:.

That leaves the thunderstorm...

Could it possibly be that the electric surge from the thunderstorm damaged the CPU (or one of the cores)?

Check the BIOS and re-clock/overclock your i7-2600K with a slightly different voltage and/or speed. If it crashes faster/slower/not, there's your problem.

While you're at it, check the ram voltages as well (1.5 or 1.35) and see if there are any anomalies there.

Again, this is just a long shot. One that doesn't require a lot of re-arranging parts. Just a reboot and some BIOS adjustments.

Hmmmm...this is a good idea will check it out.

Nope, have pretty much all of the power options on never.

I flashed the BIOS with update.
I increased CPU speed to 4600MHz from 3400(temp is surprisingly stable and I'm tempted to go higher)
Not sure how to check ram voltage the MB tuning software shows DRAM Voltage at 1.650 it never moves. The only number I see moving on the hardware monitor is the Vcore Voltage which is moving around between 1.050-1.074

The system locked up and crashed 1 hour later.

Unreal.
