Hello
I am getting seemingly random hangs in Windows 7 that I can't get to the bottom of. I'm hoping one of you awesome people can help me out?
It seems to happen most often when I'm in Firefox and I use my MMB to scroll the page - not the wheel, but using the MMB as a button so that I can smooth scroll with the little up/down arrow icon that appears on the page. This happens in Firefox 4, 5 and 6, so it's not just one bad version I don't think. It does happen at other times, but that is the most consistent pattern I can find. It also happens regardless of how many tabs I have open or what other applications are open in the background. The freezes do not happen under massive load (I can render with all the cores on 100% and it's stable) or as a result of excessive heat (max CPU temp gets to about 40 degrees C under full load).
This started happening about a month ago, but is happening much more frequently now -sometimes 5 times a day.
- Windows 7 x64 ?
- Full Retail
- Hardware is 4 months old
- Software installation is 4 months old
I have run
Driver Verifier to force a BSOD and got this info when I restarted:

Bug check description: This is the general bug check code for fatal errors found by Driver Verifier.
The driver is unloading without first freeing its pool allocations. A bug check with this parameter occurs only when the Pool Tracking option of Driver Verifier is active. This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver which cannot be identified at this time.

I have also attached the jcgriff2 info and the perfmon report to this message.

As far as I can tell all my hardware
drivers are up to date and I have updated my BIOS too.
Thanks in advance!
