Download and install AIDA32 from the following link :
http://www.aida32.hu/aida-download.php?bit=32
Once installed run the program and go to the REPORT menu and start the Report wizard. You want to run a system summary only report in plain text and cut and paste the results into a post here.
From there we should be able to begin to direct you to the drivers that will correct your problem.
NOTE : Before posting please remove your IP address which will be reported by AIDA. You need only cut and paste the top of the report (System Summary area) as their is no need for the debug info at this time.
If we need additional info not supplied by the general system summary we will walk you through obtaining such information.
EDIT :
HMMMMM....how rude. AIDA32 allows a copy but won't place the text into clipboard for pasting.
You can save the report to a file and email it me if you are so inclined.
Simply PM me or ask an admin for my email address if you want me to give it a look.
