BSOD irql not less or equal

Rats. Ran for 6+ hours and then kablooie. BSOD.. the IRQL not less or equal type. Thank goodness for the session recovery in FireFox6.

You have a silicon labs usb express driver that is not compatible with win 7. I can point you to the right site but it might take a little doing to find the right one.

Are you using any kind of Garmin GPS?

Run SFC /SCANNOW Command - System File Checker

Are you tying the silicon labs usb driver to Garmin or are they not related?

They are not related but the garmin software isn't Windows 7 compatible and is known to cause issues

Shucks. The Garmin stuff is in (more or less) frequent use. I suppose I should be glad that it doesn't cause any more problems than I experience.

No more BSODs in the last 14 hours.

I have no idea what to do about that USB driver you mentioned. Have we done all we can do? Shall I terminate the verifier program?

Edit: is there any particular Garmin software at fault or are you speaking of all Garmin software in regards to Win7/64?

Yes terminate the verifier
From what I've seen these Garmin software use old drivers, in fact the Garmin software are not old but the driver they use are obsolete. These were never Windows 7 Certified

Thanks.

Can you give me the filespecs on the silicon labs usb express driver in question? I'm not sure what to even look for.

Edit: nevermind. This looks like it/them and mostly seem related to Garmin's ANT agent.

Regarding the Silicon Labs usb driver mentioned above, has anyone here had any luck using something like DriverMax with Win7/64 to find and repair driver issues?

I discovered this over at Gizmo's freebie site.

Thinking that some of my issues may be related, I thought I'd post the results of a memtest86 run I just ran. I haven't noticed any BSOD instances for a while now, but I am getting random hangs when running Firefox or Chrome and I see cpu activity around 50%. After 15-20 seconds, the system picks up and continues. But only that app that I'm running hangs. I can open up other apps.

I decided to run the Windows7 memory diagnostics test. It told me I have a hardware issue, but is not very specific. So I d/l a copy of memtest86 v 4.2 and burned it to a CD... ran the test for 30 minutes or so and it confirms I have a memory issue.

I have two sticks of 2GB ram and 2 sticks of 1GB ram for 6 GB (6144Mb) total. How do I interpret this pic to find the faulty memory module?

Yes, this RAM is defective and should be replaced :)
