Windows 7 on Acer Ferrari 4005WLMi. I have upgraded from Windows XP Home to Windows 7 Professional. This has created real problems. The CD crive Panasonic Matshita UJ845S has stopped working along with my card reader. I have downloaded all latest drivers from Texas Instruments, upgraded with the latest detals and recovery methods I can thin of, including copying the Recovery disks and system disks to my Dell notebook in an attempt to reinstall the origional operating system. Nothing appears to work and as I cannot use the CD player I cannot load the programmes I want to work with. I have; Deleleted drivers and used 'update driver. Used Windows update. updated chipset drivers. Spoken with Acer on the premium call line. Nothing appears to work in what was a brilliant machine before upgrade. Any help would be welcome.
