Need help A couple days ago, I kept getting an alert saying nvidia driver has stopped responding and recovered. Recently my computer kept crashing mid game and gave a 6 beep code error after a restart (video card issue code). Now all i see is a black screen with the backlight on and keyboard light on. I've tried cmos battery removal and cant get into bios either. About a year ago, my 675m failed and I upgraded to 680m following the tutorial on here. I disabled my integrated graphics in bios as well. Is it possible to turn it back on? Does anyone know whats wrong? hardware failure or software failure? Not my video but my computer does the same thing as this guy's m18x Thanks for the help

mine idles around 50c also.. reapplying thermal paste may help alittle
