My Sony Vaio FZ38M keeps going to a black screen and when it reboots the screen is covered in lines of vertical blue dots. I have uninstalled graphics driver (NVIDIA Ge Force Go 8400M) and installed updated driver from Vaio. It then boots up OK but then after a while it goes to black screen, reboots into blue dots again. The only other thing I noticed is that the machine gets hotter than I can remember. I have tried all the basic checks but nothing seems to work. Any help would be appreciated.
Thanks Ibanez, I have tried that option but Nvidia will not allow download as it is a Vaio and only driver downloads fron Sony are advised. I have updated the driver from the Vaio site but the problem persists.
