I have a Biostar A880g+ in an HTPC application. I have a passive heatpipe cooler on the CPU. I'm using a desktop case, the only fan is a 120mm fan in the PSU blowing air across the CPU cooler.
I noticed that the system will often randomly freeze up with the screen looking corrupted. My first thought was the A880g chipset. I measure the heatsink temp at around 55C. Eventually, the system wouldn't even POST. I RMAed back to Biostar, they said the BIOS was corrupted. The next one had the same issue with freezing, I RMAed again and they gave me a replacement, but that wouldn't even POST.
I decided to try a different MB, Gigabyte GA-78LMT-USB3. I noticed this would would freeze the same way (with corrupt screen) even on the BIOS screen. Measuing the A760g heatsink, it got up over 65C.
At first, I'm thinking the northbridge is getting too hot. I searched the northbridge specs and saw it can go up to 95C.
I've tried a different PSU. I only have one CPU and the two sticks of RAM. I've tried one stick at a time with the same results.
Any suggestions?
