Hi, my name is Robert. I'm new to your forum and I've come because the almighty Google has failed me. The problem basically is that my CPU is overheating and it automatically reboots my PC. The cause of the problem is that it tries to run many of my programs on ONE of my coprocessors. I have an AMD Athlon X4 630 2.8Ghz. I run on w7 Pro and I have a stock CPU cooler, which is only part of the problem. I have used the task-manager to set the affinity to all coprocessors. It still runs it on the one. I'm not sure how it chooses which one it runs on. Usually it's either the fourth or the first. I'm using a tool called 'Core Temp Gadget v2.6 by ALCPU.com' to notice this. I've got expertise in this area so don't spare me the techno-babble. Thank you for the use of your forum. Have a wonderful day!
