I have just changed my OS to centos 6.5 and plugged in two monitors, both of the monitors are working but showing the same view. when I try to get the Display settings (System->Preferences->Display) I can see only one screen which is flagged as "Unknown". both of the screens are plugged into on board input. the motherboard model is : gigabyte GA-B75M-D2V I can't find any drivers for this motherboard which is suitable with linux OS.

5 minutes after I turn on my PC the onboard graphics card is usually over 80° celsius and then crashes (random colors on screen, only way to get out is to just plug out the pc).
- I haven't installed any new drivers or added/changed hardware recently
- Everything went fine until yesterday
What should I do next? Do I have to buy a new mainboard right now?
There is no fan on the onboard graphics card, only a heatsink.

The first thing I would try is to add a fan, bigger heat sink, and make sure your case is ventilated well. Check for dust and lint build up. The next would be to add a heatsink with a fan. Those are the cheapest option. If you have a free graphics slot on your motherboard, you could disable the onboard graphics card and use a new on installed in your free slot. Your mainboard is probably fine, and if you have been otherwise happy with it, I would keep it and just install a new graphics card.

If this start of happening all of a sudden, you may want to reapply some thermal paste like ArcticSilver

If your graphics cards are over 2 years old, go into your case and give everything with fins or a fan a thorough blast of compressed air. Those dust bunnies are to components, what parkas are for arctic explorers. Dust bunnies = heat.
