I followed the instructions to view ghosted devices and i have taken a screenshot of the device manager after this. it is in the sky drive for reference.
I dont want to tempt faith but the good news so far is that i have not had a BSOD in the last hour or so since updating the firmware that you suggested. The problem now is getting the graphics driver updated.
You may remember that i uninstalled the graphics driver that was originally on the computer while troubleshooting the BSOD problem. I do not remember then name of that graphic driver but it had a resolution setting of 1600x1200.
If i do a complete system restore would that bring back the driver that i uninstalled? if so i could do a complete backup and then do a complete computer restore using the samsung recovery 5 solution (20th July 2012). If the firmware update you recommended was the cure for the BSOD then i would just need to download that after i do the restore and i would have the original graphic driver back!
Do you think that would work?
cheers
