MSINFO32:
Please go to Start and type in "msinfo32.exe" (without the quotes) and press Enter > Save the report as an .nfo file, then zip up the .nfo file and upload/attach the .zip file with your next post. Also, save a copy as a .txt file and include it also (it's much more difficult to read, but we have greater success in getting the info from it).

systeminfo:
Please open an elevated (Run as administrator) Command Prompt and type (or copy/paste) "systeminfo.exe >%USERPROFILE%\Desktop\systeminfo.txt" (without the quotes) and press Enter. Then navigate to Desktop to retrieve the syteminfo.txt file. If you have difficulties with making this work, please post back. Then zip up the .txt file and upload/attach the .zip file with your next post.
