PC shut down automatically while using Chimera
Dear Chimera Developers, Recently, I found something really annoying when I was using Chimera. The problem is that when I use chimera to display CryoEM maps(400X400X400, 32 bits), my computer shut down automatically. I don't think there's something wrong with the hardware and coot or pymol is fine. This is not just an accident. It happened quite a few times, especially when I suddenly zoom in, computer is suddenly shut down. Later there would be some error massage related to the instability of the power, CPU self protection "£$%^&# ... when I turned on the computer again. But I don't think there is anything wrong with the power as well, I've run other softwares without any problem. Also, it happens to both Window 7 and CentOS 6.5 in the same PC. So it's obviously hardware level issue related to Chimera. My guess is that there might be something in Chimera that activated the self-protection of CPU or similar things. Any ideas why this occurs and how can I solve it? Best wishes Kai
Try running chimera with opengl debug and disable everything. If it is something with the GPU it usually helps. chimera --debug-opengl Best, ---------------------------------------- Matej Repic Ecole Polytechnique Fédérale de Lausanne SB - ISIC - LCBC BCH 4108 CH - 1015 Lausanne ---------------------------------------- On 5/6/15, 16:25, "kzhang@mrc-lmb.cam.ac.uk" <kzhang@mrc-lmb.cam.ac.uk> wrote:

Chimera does not know how to shutdown computers, so I agree that it's probably a hardware issue. And it's more likely to be a problem with your graphics card than your CPU. My guess is that it is a lack of cooling problem, so a blocked or broken fan somewhere, but it could be a bad or inadequate power supply, a buggy graphics card, bad memory, etc. On Windows, check the event logs for information about what's going wrong, and on Linux, check the log files.
