I was running Win8 on a Samsung 840 series 250GB SSD. Before the problem occured I had trouble playing internet videos. Several times I uninstalled and reinstalled Adobe Flash, as well as Firefox, Opera, and Google Chrome. Just before the problem occured I installed Chrome and the latest version of Flash. Videos still would not play so I disabled Windows firewall and disabled Malwarebytes and Total Defense. At that point Windows showed me an error message that said Windows was experiencing a problem and needed to shutdown. Windows immediately shutdown. After that, I got no response from the power button. When the power button was pressed the screen stayed black - no flickering, no booting. I tried removing the battery and holding down the power button for 30 seconds and reinstalling the battery. No change. TigerDirect, where I bought it 10 days ago, said to return it to Asus. So, it's in the mail now.
However, I did just receive an email response from Asus and they offered this general advice: "We don't suggest users to install a SSD in your laptop, it may cause system instability issue."
They have not seen my laptop yet, so they don't know for sure that my SSD was the problem. Their advice about SSDs seems to be a general recommendation for all owners of the G75VX.
Have any other VX owners experienced instability when they run Win8 from an SSD?
UPDATE 7/17/2013: just got the laptop back from Asus. They said one of the RAM cards died, so they replaced it and sent the laptop back to me. They installed Win8 on the HDD. I have not booted it yet. I need to reinstall my SSD which has my previous install of Win8 on it. So, when I boot it, there will be to drives in it, both with Win8 on them. I also have an external drive with a pre-cash system backup on it. Not sure how to preoceed now. I need Win8 only on the SSD. The HDD is only for storage.
