[Help] BSOD Whea_Uncorrectable_error

[TreyLe]

Hi guys, i built my pc a month ago and sometimes i would get the BSOD Whea uncorrectble error. i've been running stress tests, memtests, check my wirings and ran sfc.scannow. I also tried windows 8.1 on a SSD but still have the crash.

I decided to look at the log events and see the Event 41 Kernel Error Task 63.

Nothing seems to be wrong so then i looked more into it online but still haven't found any solution. Can you guys please help me? I'm so desperate because this problemhas been around since this pc is built and is really getting on my nerve. Thank you. i use Windows 10, i5 6600k, Gigabyte 970 xtreme GPU, Asus z170 pro MOBO, Hyper x Fury Ram and Evga 650 P2 PSU incase you need the info. P.s i dont even overlock any components.

Ah, this thing.  It's usually connected to thermal throttling.  Happened to me with my 4790k until I dropped the OC.  

I didn't overclock any of my components and have XMO off though

I have found personally that has nothing to do with temps and is actually just instability of the CPU, mainly when overclocking. 

 

OP, it could be either the CPU or the motherboard.

Try downclocking it, and see if that fixes anything.  If not it could be an issue with the mobo.

For me the temps went up when I got this error.  Might have been a false read.

Well considering my CPU was less than 60C on a 4.6GHz overclock when I got the error, I don't think it was the temps.

• I tried OC it once and it stopped for a month and now it happens again :<

Oh man I saw this thread title and cringed. I had that error as well for the longest time.
 

Two things actually caused it for me, this is on an older machine as well. It's a P45/Q Series Quad Core/ DDR2/Fermi GPU

 

First reason which fixed the majority of the issue was I had a stick of dead RAM. Once I removed that the amount of times I'd get the error dropped massively.

 

Second reason I was running a hefty overclock on my chip and it caused the VRMs to heat up enough it would cause that error and the machine would lock up and give that error. I fixed this by purchasing 2 80mm Noctua fans for about 40$ and I set them up to blow over those key areas. Now the PC runs with zero issues whatsoever.

 

So my solution would be check the following.

 

1. Airflow. Make sure you have a decent amount, nothing crazy but as long as air is circulating the case or you at least have 2 fans intake you're probably good since your computer is newer and chipsets/VRMs don't get nearly as hot these days.

 

2. If you have an IR thermometer thats easy way to check temps inside the case. but next time the PC crashes let it shut off itself, keep it off. Open it up and try to see if you can figure out if there are any parts of the Motherboard that are hot. If its hot to the touch and you can't keep your finger there then that is an issue. If that happens then you need to improve airflow somehow. I'd recommend as I did above getting some small quiet fans to run blowing over those key areas or simply adding more case fans/turning up the ones you have currently to see if that helps.

 

3. If you can't find anything that you'd deem too hot to touch. Then I'd go on to checking RAM for example which was an issue in my case for whatever reason.

Pull out all the stick you have and try them one at a time and try to replicate the crash. If one stick won't crash and the other does then the stick is dead. If they both work alone there is an issue with your board, or more specifically your DIMM slots.

 

4. If you still can't find anything If possible test the PC on another Powersupply, or try removing the Graphics card to lessen the work load and run the PC off IGFX.

If this can't replicate the crash then it could be a PSU issue or a GPU issue although I'd say more likely a PSU issue at that point.

 

After that point if you still can't find anything I dunno what else to say. It's easy to figure this stuff out if you have tons of components and can throw in a new Chip, or try a different motherboard, or find a different PSU to try but with limited hardware it is difficult.
