M2N Sli Deluxe Freeze!
I have an Asus M2N SLi Deluxe. The motherboard is a few years old and just recently it has started freezing at random times. I tried heaps of different troubleshooting before deciding it must be an overheating issue. I gave the CPU heatsink and the chipset heatpipe a good clean with an old toothbrush and the problem instantly disappeared. I had to remove the CPU fan from the heatsink to give it a good clean. There was heaps of dust stuck under the fan. Now, the CPU and chipset both run at least 10 degrees cooler and the freezing problem is gone ;)
