The NVIDIA drivers are causing a major issue and Sony seem to be doing nothing about this! Last night a system error message flashed up saying that NVIDIA drivers had stopped working but recovered. This morning i turn on my laptop and it will not freeze again and again. I have now disables the NVIDIA driver from running at startup and the problem appears to be solved. These driverrs are so out of date but according to Sony they are fine.
If you want to see how out of date they are check your version then go to NVIDIA's website and see their current version. Ridiculous!
Sony customer service is terrible
