ANSWER: Hello james

Tahnks for your question!

I have taken it out of the pool as the other experts didn't know how to answer.

I am very well aware of your issue and there is a freeware tool that encodes the blue scren messages for you that are generated out of a memory dump when they appear. they then display which system files are affected. if you google for them you can find out which drivers or programs they belong to and so know what is causing the problem and fix it.

If you need any further help please let me know and I will do my best to help you further.
PLease describe then the exact issue you have with using the program

Thanks in advance!

QUESTION: Thank you Joerg. The nirsoft blue screen view has indeed given the information you indicated, but I have no ideawhat to do with it, or which partto google for the dump files.

information is only useful if you know what it means, anf I am sorry but its meaningless to me.
I hope you can interpret it for me.
Thanks again for your help.

Hello again!

The red marked info is the one you have to keep an eye on. As that means there was conflic. goofle such files then.

Hope this helps!

If not, please supply a screenshot.

A simple copy and paste is too crowded and unreadable as it misses the formatting.

All the best!

Being an early adopter of Windows 8, I can answer a wide-range of questions regarding this new OS.


I had to support users regarding all kinds of Windows problems for many years, often "blind" over the telephone. I work in the IT industry for many years now filling in various positions for various IT and financial and health-care related companies.

I did an education as a Management Assistant in Informatics under the control of the Chamber of Commerce and Industry in year 2003.
