BSOD at random - IRQL gt zero at system service

So I've started getting BSODs constantly, 4 today alone. They happen at random. The message is IRQL gt zero at system service. After searching the internet a bit, I believe it may have something to do with:

BitDefender
ZoneAlarm (something I had a long time ago, but was removed)


I downloaded and ran adwcleaner which caught about 15 issues, including some old ZoneAlarm, as well as something called Claro, which MalwareBytes had identified as a PUP. I have been unable to complete a MB scan, as it takes so long. I've reach around 1 hour 30 minutes or so before being BSOD'd. My computer also becomes so sluggish that it is nearly unusable while MB is scanning. BitDefender seems to clash with it, thus I try to disable everything I can on it, but still can't get past a BSOD.


It began early this morning. I just moved to a new apartment two days, and have a new router, but that shouldn't matter. The only things installed directly to the computer has been moving various USB's around to different ports that did the auto-install software.

After reading, I thought about running Driver Verifier, but due to the ehhh aftermath of that, I want to work step-by-step with someone before even running it.

I've attached the dump file. Please help.


Edit: I also just noticed this in Event Viewer that hadn't appeared after prior BSODs:

The computer has rebooted from a bugcheck. The bugcheck was: 0x0000004a (0x000000007749132a, 0x0000000000000002, 0x0000000000000000, 0xfffff88009b17b60). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 120214-18782-01.


And I also just remembered, the first two successfully completed the physical memory dump at the bottom. The most recent 2 BSODs said "Physical Memory dump FAILED":

Happened again, a Vulnerability Scan on BitDefender had just finished and stated that there were some optional Windows 7 updates, which I was checking and went to hit update, and got BSOD'd. Not sure if it was just a coincidence in timing though. The updates did go through upon restarting my computer.

This is odd and probably not related, but I think a common link across the BSODs has been having my Apatronix speaker plugged into the USB to charge. Don't know if that could cause a BSOD, but I know I have errors and driver language in my Event Viewer related to USB. Just grasping at straws maybe.

Here is a fresh dump log:

I would backup my data and re-install windows. The dump said that the IRQL raised and then the computer got the BSOD.

What do you mean "the IRQL raised"?

Really hoping to troubleshoot this more than just "reinstalling windows". Do not have a windows disk at my new place, and I've tried doing full backups in the past and they have failed around 44%. Maybe my external hard drive is just screwy, don't know. Really don't want to lose anything or start over reinstalling things if i dont have to.

What antivirus do you have?
