Hey there, so my fairly new computer has run absolutely fine with unchanged hardware the last couple of months. Last night I get a BSOD once, restart and everything is fine again. Now this morning after starting the PC and opening chrome and 2-3 tabs, I get that same BSOD. And now it happens every time I try to do anything that involves the programs requesting RAM. It's a BSOD with PAGE_FAULT_IN_NONPAGED_AREA in msnkphsa.sys. So I look that file up and it turns out to be in relation to USB audio drivers. I restart my PC, go into the device manager and disable my USB audio device (which are my speakers that have an integrated USB sound card). Now the BSOD is gone but I can obviously only use my headphones that go into another USB audio interface which appears to not be the cause of the issue.

Any ideas how I can fix my issue here? I already checked if there were updated drivers for that USB speaker soundcard that's causing my issues but there are none according to the automatic Windows update driver panel.

Check on the manufacturers website for driver

Unfortunately I can't find any drivers online anywhere. It's a ~5 year old Teufel C200 USB 2.1 sound system. I did find out that you can apparently connect it with a standard clinch/aux connection as well though so I guess I could just hook the speakers into my other USB audio interface that still works and use it that way maybe. Was more comfortable with the 2 USB audio devices though...

Okay so the blue screen came back after a while. Then I remembered I had recently changed my sample rate for all audio devices to 48KHz as opposed to 44.1KHz. Changed back and now it seems gone for good. Apparently whatever driver sits in msnkphsa.sys doesn't like 48KHz.

Please or register to reply.
