Windows 7: Irql bsod

Irql bsod

Hi everyone,

I've been getting an IRQL driver BSOD for a few days now. I'm not too sure what driver is causing it because my WhoCrashed just says "Unknown".

My graphics, chipset, and BIOS are up to date.

Unfortunately, I can't upload the memory dump because its 400MB and 104MB in a .zip folder, but I can copy and paste what my WhoCrashed said.


Code:
Crash dump file:        C:\Windows\memory.dmp
Date/time:              8/9/2011 2:12:42 PM
Uptime:                 00:37:16
Machine:                
Bug check name:         IRQL_NOT_LESS_OR_EQUAL
Bug check code:         0xA
Bug check parm 1:       0xFFFFF6FC401CDE18
Bug check parm 2:       0x2
Bug check parm 3:       0x0
Bug check parm 4:       0xFFFFF80002CAC3EA
Probably caused by:     Unknown
Driver description:     
Driver product:         
Driver company:         
OS build:               
Architecture:           x64 (64 bit)
CPU count:              4
Page size:              4096

Bug check description:
This indicates that Microsoft Windows or a kernel-mode driver accessed paged memory at DISPATCH_LEVEL or above.

Comments:
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem. 
A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: Unknown .
Any help is very appreciated.

To be honest, I think it's your sidebar.exe is the cause here. Could you make a Ctrl + Alt + Delete, and delete the sidebar.exe process?

So would uninstalling all my Windows gadgets be able to solve my problem? I currently don't use them that much. They're my CPU usage meter, GPU usage meter, World of Warcraft server checker, and my AVG anti-virus tool.

Thanks, I would have never known it was something so simple.

Sadly with my luck, as soon as something is fixed another thing goes wrong.

My computer freezes on the "Starting Windows" screen sometimes and in the morning I have to turn my computer on and off about 20 times(sometimes even taking parts out and putting them back in) to get it to just show video.

I'm curious if my graphics card is breaking on me.
Is there anyway I can check my graphics card to see if there's anything wrong with it?

You could do a Furmark test. But let's leave your Graphic Card, and to a memory test by using MemTest

That'll be our first step.

I've done that test may times and gotten errors.
I've switched out RAM sticks until I didn't see errors anymore.

Right now I have 2 stick of the original RAM I had from this computer's base factory setup and 1 stick that I took from an old computer.

I'll do an overnight MemTest tonight and post if I get errors.
