RE: M17x-R3, Nvidia 580M, Intermittent Problem (Crashes, 8-beep)
After reading your post due to experiencing the same issues. I bought by R3 approx. 2 years ago and since then I have had nothing but issues with it. I have had replacement heat sinks, gpu, cpu, keyboard and now since around November I am experiencing the same issues your are mentioning.
I tend to have issues in games and the laptop beeps and restarts after seeing a blackscreen. Surely it cant be a hardware issue if their Is more than one person experiencing this?
