I recently bought a second-hand motherboard to replace an old defective one, but I cannot seem to get it to work. First off, the whole system overheats drastically over a very short period of time(1 min) but the system does not call for a shutdown. I can see some temp readings in the BIOS, where initially it can say something like -72 °C, but if I leave if for a while it will say 120 °C, while the system is configured to shut down at 75 °C. I don't know if that's overblown or what, but the CPU heatsink does get very hot, and as a matter of fact, the whole motherboard as a whole along with its heatsink in the middle as well. Another problem is the CPU Fan does not flinch a muscle above 880 rpm; it just doesn't give a bleep.
A normal startup detects all hardware(hard disk, the intel processor, the DVD-RW), but instead of booting from the DVD-RW it prompts to a System Monitor, where there's voltage and temp readings.
The Biostar MB is very limited in its F1-12 functions. In fact, it has none. I go with Tab to bring up a Hardware Monitor, or Del for the BIOS. That's it.
Attached is a snapshot of the system, with RAM, Graphics card, CPU heatsink put aside. The 4-pin connector was removed because it got in the way.
