Random BSoDs, mostly ntosknl.exe+7cc40

Hi,

I was wondering if anyone might be kind enough to have a look at the crash files that I get from my PC.

My PC is running Win7HPx64. It is about 18 months old. The OS was full-retail. The BSODs started around October 2010, for no obvious reason. Now I am getting them up to 3-4 times a day, and then none for a week at a time.

I have already done thorough scans of the HDD, RAM and driver updates with no progress.

Any thoughts would be much appreciated!

Hi,

Ok, I see. I had Comodo as the firewall, and Avast as the anti-virus so was not aware of any duplication. Anyway, I have uninstalled them both.

I also went to install MSE, only to find that it was already installed (and apparently functioning) which is a little odd, as I recall I have had to specifically disable aspects of it before to avoid reported conflicts.

I tried running sfc /scannow but it says 'you must be an administrator running a console session to use the sfc utility'. Well it is my PC and mine alone and I don't understand what that means.

Apologies, I'm not techie.

Hi,

I have MSE installed now, and fully up to date.

I also worked out how to run SFC from the Command Prompt as Administrator (google brings you to explanations as to how to, posted on these very forums by Brink).

I ran it three times. The first time is stopped at 10% verification saying 'Windows Resource Protection could not perform the requested operation'. The next two runs were fine with nothing reported.

I'll run Memtest tonight overnight. I'm pretty confident it'll be ok as I ran it 2-3 times a few weeks back and there were no issues to report.

It might be false hope, but I haven't had a BSOD since uninstalling Avast/Comodo. We'll see, I didn't get a BSOD for several days recently after updating the video driver, and thought then too that it might just have been the fix.

I'll revert!

Ok well it has been about a week, and time for an update.

As mentioned the system seemed stable for 2-3 days, but now I am getting BSoDs again, currently averaging one a day.

Six of eight of these have been Ntosknl.exe errors, the others NTFS.sys and MpFilter.sys.

Is there a way I can zip up say the last week's minidump reports and post them here, rather than post the whole large file again? Or does anyone have a better idea?

Thanks

Ok thx,

Please see attachment.

Thanks.

I would suggest a Repair Install
Since SFC could not proceed any further it could mean that some system files were corrupt
