Windows 7: IRQL_Not_Less_Or_Equal

This BSOD is really driving me CRAZY.

Every now and then it crashes, I really don't know what to do.



I have two guesses for this... Nvidia drivers or bad memory

My logs are in the attachment, can somebody give me a light please?

PS: Sorry for not being much descriptive, I don't know what else to say... I'm at disposal to any kind of questions that might help to solve this bsod :] Thanks

PS 2: Changed Processor (E6300 -> Q8400) and memories (2x2gb Markvision -> 2x2gb a brand I can't remember). Still BSOD. Must be driver issue.

PS 3: I'm not sure, and I don't know if it helps in any way, but for what I have seen, the BSOD happens when I click something. Of course it doesn't happens every time I click, but when it crashes, it's just during a mouse click. Might be crashing for closing aplications as well (mouse click on "X")

Hello KooKat!

First, thanks for your time!

Before I read your message, I ran CCleaner and got rid of some registry errors.
Then I saw your message and upgraded the Realtek 8101E driver, ran the Kaspersky tool (no errors found) and installed Microsoft Security Essentials, still had no BSOD!

I'll wait some more time and see if it solves, if not, I'll do the others steps, ok?

Thanks a lot!!! I'll keep you updated, even if it don't crash anymore!

OK, take your time

Any BSOD-s this week?

No!

Everything works fine! Not a single BSOD!

I'm not sure exactly what was causing it, but it's gone now.

Can't thank you enough for your help

That's great
Observe for another week..come back and mark the thread as solved.

I'll do it right away, pretty sure no BSOD will come up.

Okay, post back if there are any issues. Good luck.
