Question Random BSODs - SystemServiceException


Jun 6, 2019
Hey all!

Struggling with some weird BSOD issues since upgrading a few of my PC components, below is what I'm currently running with the upgrades mentioned in bold, and also what it was replacing.


  • Motherboard: Asrock B250M-HDV
  • CPU: i5-7600k
  • Graphics Card: Asus 1060 6GB
  • RAM: Corsair Vengeance 2x8GB RGB (was previously 2x4GB of standard black Corsair Vengeance RAM)
  • PSU: Corsair CX450M
  • Storage: Samsung 860 EVO 250GB (with Windows 10 OS on) - 1TB Seagate Barracuda Mechanical Drive - 1TB Sabrent M.2 SSD
  • Fans: 3x LL120 Corsair RGB fans (was originally 3 standard case fans)
  • CPU Cooler: Corsair H100i RGB - the one with 2 fans (was originally a Cooler Master Hyper 212)
During this upgrade I also reset my PC, deleting all files but keeping my OS.

Upon swapping parts, everything booted fine and it all seemed well, but then, as PC's do... we had a few issues!


I've logged every time my PC has blue screened, which has been a total of 6 times.
4/6 of these crashes have occurred while using google chrome, most noticeably while watching YouTube videos.
The other 2 times were once while I was typing in Discord, and the other crash was a freeze up while playing Destiny which didn't actually result in a BSOD, but did still generate a crash log in my event viewer.

Speaking of which, I've taken a look at the event viewer and also used the "WhoCrashed?" programme to take a look at these logs to understand them a bit better.

The BSOD's themselves have shown a SystemServiceException error.
And in event viewer I've seen critical errors about Kernel-Power (Event ID 41), Task Category 63.

WhoCrashed says 4/6 were supposedly a typical software driver bug, and not likely to be caused by hardware.
Whereas the other 2 times it seemed to cite a case of memory corruption, such as faulty RAM/overheating or a buggy driver.

Here is the conclusion it gave me:

"6 crash dumps have been found and analyzed. A third party driver has been identified to be causing system crashes on your computer. It is strongly suggested that you check for updates for these drivers on their company websites. Click on the links below to search with Google for updates for these drivers:

nvlddmkm.sys (NVIDIA Windows Kernel Mode Driver, Version 451.67 , NVIDIA Corporation)"

What I've Tried:

Since this problem is fairly new, I've only done a few things, which are:
  • I've been into my basic Windows settings and updated anything that was stacked there.
  • Using Windows memory diagnostic tool I've tested my RAM, which has come back fine on the 2 occasions I tried it.
I had been wondering if the issue could be that my PSU is struggling with the load of these new things, however most of these crashes have occurred while the system isn't under much load. I've been gaming ever since I upgraded the parts and it's seemed fine, if a little choppier than usual, which I'm not sure if is linked or just in my head.

Throughout this time I've been running MSI afterburner to check my temperatures (celsius) which sit at:
  • GPU idle: 36-40
  • GPU load (gaming): 72
  • CPU idle: 33-37
  • CPU load (gaming): 55
The GPU usage seems even, and so too do the watts, which makes me think the PSU is fine? Since it can handle the system under the stress of gaming.

My other thought is that potentially some wires could be getting squashed in the back of my case as getting everything to fit back there was fairly tight. I'm thinking of running my PC open for a couple of days to see if the crashes continue, however I doubt this could be the issue.

I know this is a long post but I'm just trying to explain everything fully :) Really hope someone can help me as it's a bit of a weird one, and I don't want to be chasing the wrong solution for days!
