Here's my tale of woe: some of it may be Vista related but the X300 is certainly implicated.
All was well until I started getting BSODs on resume from hibernation and sleep. These fingered swumx01.sys as the culprit and this is the driver for the Sierra Wireless modem. This is a much valued feature so I tried to find a solution. No one else seemed to have experienced this problem.
(Incidentally, I used a vodafone sim from an existing 3G card; this seemed to work fine and seems unlikely to be the cause of the problem. Vodafone unable to offer any help anyway.)
I even tried a modded version of swumx01.sys (having set a system restore point). This BSODed on me too so I tried to roll back to the original driver with System Restore while in Safe Mode. On booting I then found all but one of my user accounts had vanished and the remaining one would not accept any of my passwords. I didn't have a password reset disk (would it have helped?) so, with a heavy heart, embarked on the tedious job of using the system recovery disks to restore the system.
Eventually I got back to something close to a working system though of course I had to disable the modem again to prevent the BSODs on resume. A few more BSODs later (all types and almost at random) the system seemed to stabilise with the exception of a repeatable BSOD everytime I tried to run a ColdFusion web application locally. This identfied tvtumon.sys as the problem, which is a key part (I think) of Rescue and Recovery. So, gritting my teeth, I uninstalled that as well which did solve that problem.
So at least I have now have a mostly usable system back but significant bits are lacking. I'd like to get back the wireless modem and Rescue and Recovery. Any ideas on how I might set about this task?
