blue screen-shareduserdata.sys

[enricogp]

My pc started to give many bluscreens and crashes, all pfn_list_corupt or memory management. So I used whocrashed.exe to find out what was going on and it said that it was an incompatible driver, avast.

Then i uninstalled my avast and it stopeed........ now i m getting with same bluscreens, I checked whocrashed.exe and it said that the problem was in memory corruption, probably because a third party progam called shareduserdata.sys, it was requesting the update of this driver.

Problem is: I have no idea of what this is and how I can update/remove shareduserdata.sys. Someone has any idea of how I solve this blue screen? ( screen shot atached, see the top crash)

To me it looks like a memory issue and not a driver. The memory probably faulted at loading a driver. You uninstalled Avast and still get the BSOD error message.

 

Try taking out a a stick one at a time and see if the fault goes away.

 

Also run the Windows Memory Diagnostic.

 

Go to Control Panel. Change view by: to icon view.

Click on Administrative Tools then select Windows Memory Diagnostic.

Well, I solved it. I don t know how. I changed activeX options in internet explorer ( ccclaner had found many activeX errors in register), also I ran the memory diagnostic tool.

The blue screen apeared 1 more time, but since then nothing..... thanks for the help

Hi, firstly glad to hear all is OK now.

However, I must warn that we never recommend using registry cleaners, without a very good knowledge of the registry they can do serious harm.

 

Have a look at these two different articles and read why the authors do not recommend registry cleaners. They say a lot more than I can.
