Kernel Power 41 (63), tried all solutions (Windows 10)

CrazyCanuck84 · Jun 16, 2016

Past few days, I've been getting Kernel Power 41 (63) errors, which is what the Event Log told me after having the computer freeze and needing a hard restart.

I've run Memtest, and my RAM is fine. I've removed/reinstalled my GPU. I removed the wireless card, as I never use it (it's always plugged in directly). I did a fresh install of Windows 10. All drivers are up to date, including Realtek HD Audio, which from some Googling appears to be suspected of this error. Windows 10 is installed on an SSD, which appears fine. Majority of programs and games are installed on a standard HD (WD Blue 1TB).

My GPU is a 980 Ti, which has a 600W requirement, which is what my PSU is. The PSU is also a few years old.

My other issue is potentially the PSU, but from researching, if it's a PSU issue, the computer will reboot. Mine freezes and requires me to power off the tower, then turn back on, so I don't imagine it's a PSU issue, but I'm not the expert. Lastly, this has just started occurring the past few days, and I've had this GPU since October. So again, in my mind that sounds like it rules out the power.

Full specs:

Mobo: ASUS Z97K
CPU: i7-4790 (not overclocked)
RAM: Kingston HyperX Fury 16GB (2x8) DDR3 1866 (installed in A1 and B1)
GPU: ASUS Strix GTX 980 Ti 6GB (not overclocked)
OS: Windows 10 Home 64
PSU: OCZ ModXStream-Pro 600W.
Any possible suggestions? I'm all for replacing the PSU and will likely do so tomorrow or Saturday, but looking for suggestions beforehand.

Thanks!

I'd entirely REMOVE the Realtek HD Audio and try it with the standard windows HD audio driver that would be my first step.

PSU model? You failed to mention it. It could easily be causing it by shutting itself down from protection circuitry.

Oops, sorry. I'll reply to you and also edit; it's an OCZ ModXStream-Pro 600W.

Would the PSU cause freezing, though? I imagine a faulty PSU would cause the whole computer to shut down when itself shuts down, as opposed to just freezing?

CrazyCanuck84 :

It can cause both. Yes it indeed can cause freezing and is usually the #1 reason for hardware-caused freezes. Do you have a spare one to try?

Mark RM :

I did try this, and the issue persisted. I'm fairly certain it's not a driver issue (for any component).

CrazyCanuck84 · Jun 16, 2016

turkey3_scratch :

I do not, but as I said in my initial post, I'll be picking one up tomorrow or Saturday.

Any suggestions on what to get? 600W is a minimum, I'm not picky about make, although Corsair does seem to have the best ratings.

(If you do suggest any, please do so with something .ca; not necessarily for price, but for availability)

Under full load you rig is a 400W rig. I can think of a lot of 550W units and 450W units that would be perfectly fine with that machine. I'd recommend the Corsair RM550x as an expensive option. A cheaper option is the Seasonic G Series 550.

CrazyCanuck84 · Jun 16, 2016

turkey3_scratch :

Can you explain the 400W number? The GPU alone says it requires a 600W PSU. Is that just a "safe" suggestion by the manufacturer?

Thanks for the PSU suggestions. I've put a hold on the Corsair 550 and will check it out tomorrow.

The GPU recommendation is about as important as a walnut that falls off a cliff. That and "600W PSU" also has zippo meaning to it since there is no standardization by which labelled wattage is made. Labelled wattage is a meaningless and deceptive value that poisons the industry (ha, well, maybe that's a little too far).

Fair enough.

Thanks for the info. I'll report back over the weekend once I've been able to let it run with the new unit.

What one are you getting? Also, just to be clear I'm not 100% sure it's the PSU, it is just what I suspect. The motherboard could also cause this, but it's most likely the PSU.

Corsair RM550X.

Is there a way I can test the mobo for that kind of possible defect? The whole computer itself was built in mid-2014 (PSU was a year old at the time), so I don't know what the lifespan or rate of failure is for a mobo.

turkey3_scratch · Jun 16, 2016

No way that I know of. Well, actually, running Prime 95 version 26.6 is good to test the stability of the motherboard. It doesn't put load on the GPU so less load on the PSU.
