This might help to understand things.

What does the COM Surrogate do and why does it always stop working? - The Old New Thing - Site Home - MSDN Blogs

I would start with sfc /scannow following the instruction.

SFC /SCANNOW Command - System File Checker

It seems to only happen once and awhile upon startup.

Thanks

Are you having any other problems with your computer. Anything not working like a printer or anything plugged into a USB port ect.

What anti virus and firewall program are you using?
Please list all cleanup, tuneup ect. programs you use.

This will also help.

I have been reading your previous problems. I think we need another one of these.

Windows Genuine and Activation Issue Posting Instructions

The laptop is Dell15r 5520 new and I have yet to connect anyting to it, with the exception of a flash card that was removed.

I'm using Zone Alarm Internet Security Suite. Have used CC cleaner I think once.

This laptop came pre-installed w/ McAffe Antivirus I did have a lot of problems removing that, I eventually did. Also I got some tech support from what I though was Dell Support but turned out to be a NON- Dell company after I relised that they were not I told them I did not want any help..

At that time they installed Mozilla Friefox somehow to run w/ IE9 but not be seen, the reason that they did this I had a hell of a time connecting wirelessly. It woukd take forever, everything seems to be working ok and I only get the com error upon startup and that is only occaisionly.

Could possibly be from having a weak wireless signal?
