I suspect many users will already be aware that Sony recommend that updates be downloaded from their site only, not from third party sites. The reason being that Sony do not necessarily use 'over the counter hardware or software' (including 0S). For example the graphics card NVIDIA GeForce 7600GTL in the XL202 is a Sony specific version of the retailed GT7600, and is therefore not supported by NVIDIA. However, both Sony and NVIDIA support are very surprised that the graphics driver that I downloaded from the NVIDIA site would have disabled any ability to roll back to a previous configuration. In the first instance, they both believe that the problem is with the hardware, and for this reason Sony have suggested that the machine be returned for repair, effectively ending their e-support. Sony quoted £212 for diagnosis only, repairs would be extra!!!!
I personally believe it is the graphics driver that is the problem, but until I can get access to a DVI enabled monitor to try out Chaffbox's recommendation this will remain on the backburner for me.
