Hi,

It's basically a blue screen, "windows went into error" or smth like this, it also says me to google about this problem : WHEA_UNCORRECTABLE_ERROR. Re-installing windows several times didn't help.
I'm having this error kinda every 2 weeks. I noticed that the error eccurs much more frequently when my cpu is under high usage (90-95%), for example, when rendering movies or converting them to another types of files.

I'm using Intel core i5-4690k with custom "Be quiet!" cooler (not liquid, just a big radiator). Standart clock - 3.5ghz, turbo mode - 3.9ghz, mine is overclocked to 4.57ghz. The temperatures never reach more than 60 degrees of celsius. Any ideas?

[Solved]

1. I've solved the problem by leaving win8.1 pro and installing win10 pro instead. Haven't seen a blue screen on this version of windows yet.
2. RAM is OK.
3. It is not a cpu problem, i spent some time testing it lowering the frequencies. It might be my GPU. I've had such a problem with amd radeon hd 5670 (3-4 years ago)(blue screen every time i open up a game). Then i switched to nvidia gtx 760 (now i'm using it 1.5 years), no blue screens while gaming, but video rendering is its problem. Sony vegas 13 pro stops working after ~5-20 mins of rendering. Turning of gpu acceleration helped, but increased the rendering time by 20-30%. Now i am confused about choosing my next GPU.
make sure with the power off all the ram on your pc is locked in. run the intel cpu test make sure the cpu is fine if it is from a usb stick run memtest86 overnight if there errors pull one stick see if the errors follow one of the ram sticks. if memtest is fine download hardware info 64 bit set it to sensor and logging make sure the 12v rail is holding.

I've been using these overclock numbers for more than a year now, all tests say it's working great, temps always stay behind 60. It's awesome for gaming, but rendering and converting videos are successfully made only from 2nd time. I don't understand the word "unstable", it only happens once in a month when using daily.. ok, i'll check the ram and try to reduce the overclock rates.
 

Video converter software typically uses the highly optimized SSE command set and thous hardware implemented commands are typically the first to fail while overclocking. On the other hand: 4.57ghz means a 17% increase compared to the turbo mode. That results in max 8% performance increase on the desktop and sure less in games. But if you find that awesome....

Just going to throw this out there one more time before I pass out. I had the same issue over the last 3 days you can read the full story here http://www.tomshardware.com/answers/id-3064671/whea-uncorrectable-error-solution-thermal-paste.html see if anything sounds familiar. What worked for me was changing the thermal paste. Disclaimer this solution has only been working for the last 2 hours or so and I am still testing as i type the case is literally open on the floor in front of me and everything is not back together but my system would not even post after getting a few WHEA BSODs and now its back up and running after swapping out the thermal paste. For me the paste preinstalled on the I7 lasted just under 2 years.
