BSOD randomly occurs - error 0x0000000a - ntoskrnl.exe+74ec0

Hello

Several months ago I started getting seemingly random BSODs occasionally. However after attempting to find the cause on my own for a few weeks, they seemed to stop (I was updating drivers and poking around at trying to identify if it was a hardware issue). More recently (approximately a month or so ago) the BSODs started again. I honestly can't think what may have been changed or installed on the system to cause this.

I also tried a memory test and this didn't seem to reveal anything.

I have attached the dump files along with sys information any help would be appreciated.

Hi James.

Update the display driver to the latest. Drivers - Download NVIDIA Drivers

Then opt for some basic hardware tests.

► Stress test the Graphics Card using Furmark.
Video Card - Stress Test with Furmark
Take a screenshot of the furmark window before closing it. Upload the screenshot for us. Also let us know if you have experienced any artifacts or crashes during the test.

► Stress test the CPU.
Hardware - Stress Test With Prime95
It saves the result as a .txt file in the prime95's folder. Upload the file for us.

► Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest86+ for at least 8 consecutive passes.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

► Check if the Power Supply Unit (PSU) supplying adequate power to the computer or not.
eXtreme Power Supply Calculator - The only power supply calculator trusted by PSU manufacturers and computer enthusiasts
Also let us know the wattage of the PSU that you use.

► Is the computer hot? Report us the heat of the computer after a couple of hours of your normal usage. Upload a screenshot of the summery tab of Speccy. Alternatively, you can publish a Speccy snapshot too: Speccy - Publish Snapshot of your System Specs .

Let us know the results. Some further steps may be needed depending on the results.

Hello Arc and thank you for the reply

I'll update this post as I am gradually running the tests.

NVIDIA drivers were up to date already. Ran the FurMark test, no artefacts were noticed and the system did not crash during the stress test. I have attached a screenshot of the FurMark window.

Running Prime95 CPU stress test as I type this, will leave it running for 2 hours as requested in the Prime 95 guide you linked, no issues so far after 15 minutes.

Had to pop out and needed to restart the PC for something so for fear of the CPU being dangerous tempteratues while I was out I stopped after an hour. I will run a 2 hour test tomorrow but the 1 hour test showed no issued and attached the file anyway below as test1.txt

BSOD error 0x0000000A occurs a lot recently !
It's a long story, but I will try to make it as short as possible. First of all, that's not the only BSOD I get, I get a lot of different other BSODs, however this one shows up the most, and I suspect it's because of my RAMs, as it only occurs when I load stuff like games or so ! The second...
