I got my first BSOD yesterday, it was the first i have had, which was a WHEA_UNCORRECTABLE_ERROR I found out it was related to Kernal power but I didn't know what to do, to fix it. Today I got a BSOD on CLOCK_WATCHDOG_TIMEOUT. I have no idea what is going wrong, these are the first BSODs I have ever had, and my computer has been running fine recently. I am running Windows 10 and I have had it for a few months now but Im getting problems now. Both times I was playing a game when it just restarted with the blue screen. Please help, many thanks Tom.

WHEA_UNCORRECTABLE_ERROR,

"This is a bugcheck generated directly by the CPU. Most often it is caused because of incorrect voltage being applied to the CPU.
This can happen because of incorrect settings being applied to the BIOS (often resetting the BIOS to the defaults or updating the BIOS helps) Sometimes it indicates that a Power supply is outside of its correct voltage range. (power supply voltage regulators or mother board voltage regulator is in the process of failing."

thankyou for the thread it is helpful but I am still not sure what exactly has been causing errors, what would be the best way to find out what is causing mine? I have never overclocked my cpu, but i got both errors whilst running games (presumibly whilst my cpu is hot. Do you think overheating may be the cause to the issue?

If you have a stock cooler and you don't overclock I don't see how the CPU could overheat. With an aftermarket cooler temps should be even more lower if you have one. It'a pretty clear that W10 is for whatever reason causing this nonsense, I would reset the BIOS settings as suggested in the other thread I linked, you can of course change stuff back to how you want it like the Boot Order. Just to make sure none of the BIOS settings are causing it.

You can try this as it seemed to work for someone: open the Start Menu, search for the Device Manager, open the Display Adapters section, right click on your graphics card "NVIDIA GeForce GTX 970" with a right mouse click and select "Update Driver Software..." option and let it do its thing.

Another thing that worked for someone is flashing the BIOS, if you don't know, it means to update the BIOS with the newest version, this would be done by downloading the newest BIOS version off of your motherboard makers website and putting it in a USB drive, inserting the USB into your PC and going into BIOS to find a setting that says something about flashing BIOS, atleast this is how I understood it. Do try the other things first before flashing the bios. There are a lot of guides for the BIOS flashing if searched from google.

Also if you see any yellow marks in Device Manager it means there are devices in your computer that don't have a driver installed for them. Do tell if there are any yellow marks.

You could also install this and run it: http://www.intel.com/content/www/us/en/support/detect.html If it finds nothing just uninstall.

I have reset my bios settings to default, my graphics card drivers are fully up to date, my intel drivers are fully up to date. I think my cooling issue is because i swapped out my cpu recently for an i7 4790k and i did not replace the thermal compound, and my case does not have a outtake fan either, these may be the problems but I should have that problem sorted tomorrow and then we will see if that was the solution. Although I have heard the BSOD can even be caused by windows 10 is this true?

As a general rule when changing your CPU/Motherboard it's good to do a fresh install of Windows because low level files and the drivers of the old components can mess stuff up easily. Also, when installing a new CPU it's recommended to apply new thermal paste after cleaning the old thermal paste out of the heatshield of the CPU. And making sure to invest a bit of time in cleaning so it's as clean as it can be for the new thermal paste.

I read something about Windows 10 updates causing this :s I guess it's bugs that need ironing out as they say ;)

In school I was to fix two old computers and I accidently had swapped their motherboards, because of this it everything went to hell. Had to do all kinds of stuff, sadly I cannot even remember what I did but I got them both working. You learn to mark components with something so they don't get mixed when this kind of stuff happens. As frustrating it is, it's a nice feeling when you get it fixed.
