BSOD 03b system service exception win32k.sys

I had another BSOD, this time 001A, memory management.

Chrome had been acting funny for a little while (a couple hours)--sometimes when I opened a new tab and went to a website, the page would stop responding to scrolling (either by grabbing the scrollbar with the mouse, or using the mousewheel). I could still click links within the page, but if I went to another tab and came back, the page wouldn't repaint (it would display whatever was on the tab I had just swapped from).

Refreshing the page a couple times, or reloading it in a new tab (sometimes several times) would fix the issue.

The crash came after chrome had been doing this, and then I closed chrome.

OP updated with new crash dump.

Prior to re-enabling driver verifier I started having some MASSIVE issues with game video--huge sections of the screen would turn black (leaving maybe 20% of the screen rendering normally).

I enabled driver verifier and rebooted, and could launch games fine, but there was green pixelation and flickering over the entire screen (looks like if you just slightly pull out your monitor cable).

No BSOD at this time though.

I verified all cable connections, and tried disabling SLI.
With SLI disabled, I tried launching a game with each graphics card running the monitor, one after the other.

Neither displayed the artifacts/flickering. I enabled SLI and tried again with each graphics card, both displayed the flickering.


I reseated both graphics cards in their PCI-E slots, swapping primary & secondary cards (just for kicks).

With SLI still enabled, I rebooted, and though the computer finished booting, it did not get past the startup screen. (I got the bootup musical bit, but the screen was stuck displaying the startup screen). Swapping to the second graphics card showed my normal desktop--swapping back to the main graphics card (swapping cable, that is) did not display anything.

I did something or other and rebooted--got a couple BSODs in a row (trying to reboot several times). Those are in the OP's attachment now.

I swapped the video cards back, booted to safe mode, disabled verifier, and rebooted. (SLI still enabled)
Got a 1600x1200 display instead of my normal 2560x1600, and no nvidia control center in context menu--the driver didn't detect a compatible device.

Swapping the cable to my other card fixed it.

Disabled SLI and rebooted again--both cards work fine.

I then replaced the SLI cable with a different SLI cable, and so far everything works fine. No flickers in games (with SLI on), etc.


So, my guess is that the SLI cable had something wrong with it, though I was also suspicious that maybe my primary PCI-E slot had some issue.


Anyway, will re-enable verifier and see what happens, but I am interested in what happened with those BSODs, if someone wants to take a look at the latest ones.

Thanks!


EDIT: Upon enabling verifier & rebooting, got an immediate BSOD while windows was starting. OP updated again. (The crash from 9:30 PM today, the other 2 from today are from prior to swapping the PCI cable... not sure why one is labeled 3PM, as I didn't have any crashes until 8:45 or so, when I had 2 in a row)

Disabled verifier and everything seems fine (I know it isn't, but is much better than with the other SLI cable--no symptoms currently, other than failing verifier).

I took a look at my latest dump file and it appears that this is the culprit:
nvoclk64;NVIDIA Enthusiasts Platform KDM

Also, I have started seeing artifacts again while playing some video games--entire sections of the screen going weird and black.

I'm getting rid of the beta drivers supposedly needed for Guild Wars 2, and installing release drivers. I'll see how that works.

I was talking about the latest dump I posted.

I installed normal NVIDIA drivers, no help.
Turns out nvoclk64 is from the performance/system utilities module--I uninstalled it as I have no need for it (I use MSI afterburner).

Will see how that works.

Have been running driver verifier for over 24 hours now, and no crashes.

I'll disable again and see how things go.
