Hello gregevan and welcome to Sevenforums.
Your provided nfo tells that your BIOS date is a pre 2009. Your hardware might be incompatible with the actual Windows version. I'd suggest you to run the Windows 7 Compatibility checker.
Windows 7 Compatibility: Software Programs & Hardware Devices: Find Updates, Drivers, & Downloads
If some of the hardware parts are not compatible, we'll try to update your BIOS.
Return with the results.
