nvlddkmdm.sys

[Junkers]

This is somewhat a repetition of a similar problem I had a few months ago. I've encountered this "nvlddkmdm.sys" error again and have done steps suggested last time i.e reinstall the drivers and run memtest. Having installed the newest drivers it still happened. Got round to running memtest86 and there was no errors so I'm somewhat stumped. I'm aware it's something to do with my graphics card but what? Got a screenshot of the last error:

Running Win7 32-bit, 2GB RAM, Nvidia 8400GS, PC is 3 years old

Hmm try running sfc /scannow (cmd run as admin)

 

[Junkers]

No problems apparently.

 

[CheckPoint]

[Junkers]

[Junkers]

Yeah it's that :laugh:

Hmm just wondering is this card overclocked or does it ever overheat?

 

[Junkers]

I don't overclock. Chances are it could be overheating. It's a "space saving" PC and space inside it is pretty tight. Plus where I have it isn't exactly the best ventilated area but I've seen worse workspaces

Mind telling me the temperatures?(also can you upload some of your dmp files)

 

[Junkers]

I've not got anything to read temperatures and I'm not entirely sure where the dmp files are, sorry :laugh:

 

[CheckPoint]

C:\Windows\Minidump also download HWMonitor to check temperatures.

Here's the latest .dmp:

Define "cleanup". You mean like clean up inside the case? Or software-wise?

 

[CheckPoint]

i mean clean the graphics card (your cpu needs a cleanup too)

 

[Junkers]

Ah alright. I haven't got a specialised vacuum for my PC so what would be an ideal way to clean it? Bear in mind I'm limited for space because it's space saving PC. Would a cotton bud be alright?

 

[CheckPoint]

Well you can remove the screws and get rid of the dust from the heat sink and regularly
(I gtg sleep now)

 

[Junkers]

Alright I'll do that later, cheers mate!
