Windows 7: Manufacturer VISTA drivers to fix performance issues.

I am currently experiencing slow performance on a Windows 7 RC 7100 laptop.

Specs: See My System Specs

I have run RadarSync and all drivers are up to date, however when I check the device manager, the following have exclamation marks;

- Mass Storage Controller
- PCI Simple Communications Controller
- Unknown Device

I am considering installing the Manufacturers Drivers for VISTA via "Troubleshoot Compatibility" mode as opposed to the Windows Supplied drivers.

I traced the problem to the fact that it was also slow in Windows XP. I suspect a hardware problem.

I am now running on a different laptop and it runs fine.
