Also what is the service tag number on your system?

Thank you for your prompt response. have done as you advised. I hope i have attached what you asked for correctly. Apologies, my computer skills are very basic. I hope you can help me.

And the service tag number on your system? It should be on the bottom or the back of the system. This will help me find the correct driver you are missing for your exact model.

Have you found the service tag number foxes?

the service tag is DR37RB1

OK lets try this a different way then.

Download DriverMax and have it scan your system. It will open their website with all the out of date drivers you can update. With the free version you can update only 2 drivers per day so if you have a lot of them it will take a few days to get everything updated. I have been using it for about 4 months now and like it better then any other utility out there for keeping my drivers up to date.

Any update with the issue yet?

no it did not help. it just said unknown device and cant re-install.

Did DriverMax find a list of drivers that needed to be updated? Can you get screenshots of all the drivers it found that need to be updated please

Are you still having problems with your issue? It has been 15 days since your last response and I was wondering if the issue has been resolved? If so can you explain how it was resolved so others may be able to fix it if they have the same issue. If not please let us know and we can continue with helping you to resolve the issue.
