Due to the fact that the motherboard failed on my HTPC, I decided to dig through the closet to see if any of my old motherboards would work. Out of many, I found one that did...at least partially. I understand when a motherboard either lights up the monitor or doesn't, but this one is different. When I power it on, it does light the monitor in a normal fashion, but only for a few seconds. Naturally it complains about a bad CMOS checksum, but before I can change anything in the BIOS, it turns off, and can't be powered back on until I remove power to the motherboard for a couple of seconds. Unless someone can offer a suggestion, I will probably just order another motherboard, but it would be nice not to have to make the expenditure, particularly since this system is socket 939, which has become obsolete. Which means that I would have to buy a used motherboard, the idea of which I'm not fond of. EDIT: In case it makes any difference, the MB that I'm testing is a MSI K8T Neo 2 (MS-6702 version 1), with a fresh CMOS battery.
