The Nvidia 260M card seems to have blown on my M17x. The on-board 9400 still works, but the device manager does not even recognize the 260M. Hybrid is enabled in the BIOS. So my questions are - is it easy enough to replace myself? And where can I get my hands on the GPU? It is not something you just walk into a shop for is it? And finally - is it relatively easy to run SLI? At the moment it is only the single 260M with the on-board 9400. The shops here said I need to send my laptop in to be fixed as Dell does not sell the spare parts separately. How accurate this is I do not know.
