I had some major stability issues problems with my XPS Studio 1645 and had to reinstall Windows 7.  Everything is great now except I'm still missing one driver for a Base System Device.

If I check the system hardware status Windows will search and "find a solution" which then prompts me to download and install a driver for the memory card reader but when I do so, nothing actually happens.  I reboot and the problem is still there.  I have tried to manually install the chipset driver as I've found some info online suggesting that this might be the problem but to no avail.

Thanks.
