my son has an M17xR3 with a 2 GB GDDR5 NVIDIA GeForce GTX 580M graphics card. Recently when the laptop is under load the screen goes black but the laptop appears to be working. After a period of cooling down the laptop works again. After a quick search on the net it looks like the graphics card might be the culprit. If that is the case, is it possible to replace the NVIDIA item with something more reliable? Cheaper?
Thanks in advance.
