Persistence module stopped working

Just happened this morning, I don't why, I didn't do anything the day before that stopped working, already did a system restore to 4 days before this problem started, but still happening. Also, when it happened, I got some BSODs, unfortunately, system restore wiped the other 4 .dmp files.
Code for the persistence module.:

Edit: I updated my graphics card driver to 320.18 WHQL, when I saw the official forum (https://forums.geforce.com/default/t...ased-5-23-13-/), I saw that there are complaints about the driver, others are getting BSODs, is this connected? I still have my CD installer for the 314 version, should I rollback? I installed the 320.18 driver a week ago (more or less, but surely, it's around May that I installed it and not at June).

I clicked the rollback on the device manager, it rolled back to 311.06, the persistence module problem is not popping out for now, I also verified this on event viewer, nothing about persistence module appeared, but I have to wait to really know if the problem is graphics card driver related or possibly others.

Disregard my post above, it's still happening, it happened when I turned on my PC.

Edit: I disabled igfxpers.exe at startup using msconfig, I'll just observe again if it still happens.
