I have an unusual but annoying problem with my MBP. The problem occurs often when running my laptop with an external monitor connected, and watching YouTube in Chrome. The problem is that the video will (seemingly randomly) freeze, audio will continue playing, and the computer becomes completely unresponsive aside from the mouse still moving. If I then shut the lid of my laptop, eventually the computer will sleep, but the screen remains black (no backlight) when attempting to wake it up again, although you do hear the CPU fan and HDD spin up like normal.
I have located the exact location in the log files that the crash occurs. The relevant portion is here.
I believe that the point at which the crash actually occurred is here:
15/04/2015 10:44:05.000 kernel NVDA(OpenGL): Channel exception! exception type = 0xd = Graphics Engine Error (GR Error 5) 15/04/2015 10:44:05.000 kernel IOVendorGLContext::ReportGPURestart 15/04/2015 10:44:25.000 kernel NVDA(OpenGL): Channel timeout! 15/04/2015 10:44:45.000 kernel NVDA(OpenGL): Channel timeout!
My question is this; is it:
- A hardware problem (with the graphics card)?
- A software problem (with the OS)?
- A software problem (with Chrome)?
Since the crashes are sporadic, this is unfortunately not easy to reproduce at will, although they happen often enough to be a serious problem.
My MBP is a mid-2010 15-inch running OS X 10.10.3. The graphics card is a NVIDIA GeForce GT 330M 256 MB and I'm using Chrome 41.0.2272.118.
Any help or advice on this problem whatsoever would be greatly appreciated.
