BSOD Error BCCode:3b

It seems you are missing an ASUS driver.
Driver Reference Table - AsUpIO.sys

Code:

Please remove the overclocking while troubleshooting, it is not smart to overclock anything on an unstable system as it might cause more instability.

The reason that driver probably looks like it's missing is I uninstalled the ASUS suite and it most likely deleted this driver in the process. I don't believe I am currently set up in overclocking mode. Just got another BSOD. The error code is back to 3b so it looks like nothing's changed. Why is it so difficult with all these tools to pinpoint the exact cause of these recurring BSOD's? There has been a lot of time invested to solve this but it appears that we are not close to figuring it out. Any other ideas? Thanks.

Who says there is a single cause?
A BSOD could have so many causes, you wouldn't beleave.

Maybe, but all I know is the BSODs started occurring 2 weeks ago and after all the time I've spent trying to fix this it seems like I'm no closer to resolving this problem. Given the disruption these cause a user I would think Microsoft would provide some better tools for troubleshooting. It's going to take many more hours to rebuild this system on a new PC but I guess that's what I'm left with at this point unless you have any other ideas. Thanks.

Please run the Microsoft Uninstall Fix it to see if there is some leftover from ASUS AI Suite

Ran the tool and it didn't find any evidence of the ASUS Suite still installed. Any other ideas? Thanks.

This kind of a suggestion is one I do rarely.

Install ASUS AI Suite II again and remove it using Revo Uninstaller
Download Revo Uninstaller Freeware - Free and Full Download - Uninstall software, remove programs, solve uninstall problems
There is a chance the removal process didn't remove AI Suite properly.

OK, I did this and got at least one more BSOD. Here is the updated collector file. Anything else I should try?

The dumps are again blaming the nvidia video driver.
But, because it might be possible that the data this driver gets is already corrupted before it executes the data my guess is that it starts with the memory. Usually memory corruption would come up in that case, but I think that what happens is that the driver gets data from multiple places from the memory, only 1 place is corrupted but it hasn't been noticed by the system and because of that memory corruption doesn't come up in the dumps.

I honestly don't know if it is true what I say, because I have no idea how it is going, but I simply think it is worth a short to test the memory.

Diagnostic Test

RAM TEST

Run MemTest86+ to analyse your RAM. MemTest86+ - Test RAM - Windows 7 Forums

Note

MemTest86+ needs to be run for at least 8 passes for conclusive results. Set it running before you go to bed and leave it overnight. We're looking for zero errors here. Even a single error will indicate RAM failure.

I replaced the RAM with new about 5 days ago. Before I did I tested it and there were no issues. I don't think it's the RAM. Do you think I should replace the video card? I was also thinking about booting from the Windows 7 install disk and running a repair of windows. On the other hand I haven't seen a BSOD for about 12 hours. Your thoughts?
