Windows 7: help! random bsod for 6 hours

help! random bsod for 6 hours

first let me point out this is happening on my gf computer.

got a bsod this morning at around 3 ran the repair option thinking all was good started normal only to be met by another.
thinking it was a hardware issue i started a long process of elimination finally after taking out the first ram stick it seemed to stop but i wanted to make sure that was the problem.
I swapped it for the second spot ram and still no issue after about 30 min (blue screen was happening every 5-6 min after start up)

put all 4 back in and blue screen after clicking chrome.
well now i think its software so i just save everything to the second hd and format the main one problem solved.
nope, got 2 blues while re-installing windows and they continued and now i have no clue what to do so after much searching online i come here.

these (should hopefully) be the last 3 dump files from her pc.
i dont know if posting from my pc will mess something up but her's wont stay on long enough.

Welcome to the forums xanifer and sorry for the slow reply,

BugCheck D1, {ffffffffffffffff, 2, 8, ffffffffffffffff}

Probably caused by : CLASSPNP.SYS ( CLASSPNP!TransferPktComplete+1ce )
Usual causes:  Device driver
This bugcheck indicates that a driver has attempted to access a invalid memory address and then attempted to execute a region of memory, while the IRQL level was too high.

Okay, from what I can interpret from the call stack, is that the I/O Manager has finishing processing all the current IRPs from device drivers, and then something issued a region of memory to be paged, which then lead to the bugcheck since this is a illegal operation.

However, there doesn't seem to be any symbols available for the module which called the page fault to be issued.

I would suggest running full scan with !avast (fully updated) and then running a full scan with Malwarebytes : Free anti-malware download.
