rayjun Posted September 11, 2013 Share Posted September 11, 2013 I've been plagued by a weird crashes since Snow Leopard I'd hope to rid of when upgraded to Mountain Lion but the problem persists. The screen will turn to a random colour with vertical stripes of another, as the image illustrates, and happens during YouTube video playback. The crash occurs a few minutes into the video, sometimes longer, or doesn't crash until I'm into fifth movie or so. When it happens I had to hold the power button to reboot. It also crashes when I run Ultimo Online under XP inside a VirtualBox. Other than that the system is stable, I could run Office Apps, Adobe CS5 products, Logic without a glitch. My specs: Asus P6T Deluxe V2 Intel 2.67 Core i7 ATI HD 5770 6 GB RAM 1 TB HD + 1 TB Time Machine ML 10.8.4 DSDT.aml specifically for my board Flash player is the most recent version Onboard audio and firewire is disabled as I'm running approved Firewire card with Apogee Duet soundcard org.chameleon.Boot: <dict> <key>Default Partition</key> <string>hd(0,2)</string> <key>EthernetBuiltIn</key> <string>Yes</string> <key>GUI</key> <string>No</string> <key>GenerateCStates</key> <string>Yes</string> <key>GeneratePStates</key> <string>Yes</string> <key>GraphicsEnabler</key> <string>Yes</string> <key>Kernel</key> <string>mach_kernel</string> <key>Kernel Flags</key> <string>-v darkwake=0</string> <key>Legacy Logo</key> <string>Yes</string> <key>Quiet Boot</key> <string>Yes</string> <key>USBBusFix</key> <string>Yes</string> <key>UseKernelCache</key> <string>Yes</string> </dict> I've tried different settings in BIOS, that didn't help. Looked into editing the DSDT but that's the last resort. Please could someone gives a clue or hint how to resolve? Many thanks. Link to comment Share on other sites More sharing options...

The_Village_Idiot Posted September 12, 2013 Share Posted September 12, 2013 Try booting with -v and see where the error is. Can you boot to the screen with -x? Link to comment Share on other sites More sharing options...
rayjun Posted September 13, 2013 Author Share Posted September 13, 2013 Try booting with -v and see where the error is. Can you boot to the screen with -x? No errors that I can see. It's not that I can't boot, it's trying to prevent it from crashing when watching Youtube. I believe it's related to graphics acceleration. Added AtiConfig flag to org.chameleon.Boot.plist seems better, but crashed after a day. <key>AtiConfig</key> <string>Vervet</string> Going to try: <key>AtiConfig</key> <string>Hoolock</string> Cheers Link to comment Share on other sites More sharing options...
