I don't know if I can help, but I'll try. The fact that your D drive doesn't recognise any discs could be that your machine doesn't know it's drive D. Suggest you go to your Control Box and d/click System, then Device Manager. Click the + sign next to CDRom and then highlight the first one and click Properties (at the bottom). Click Settings and make sure the drive letter in 'Start drive letter' and 'End drive letter' are correct. Do this for each of your drives. Whilst there you can decide whether to make them 'auto-start' as well. Any changes and you'll have to reboot.
As far as your IE is concerned there may be a conflict. Click Programs - Accessories - System Tools, then click System Information, and select the 'Tools' tab and select 'System File Checker' and select the latest version of any files.
Failing that, I'd delete IE and go to Windows Update and download a fresh copy.
