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).
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. | ||||

This question is unlikely to ever help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. See the FAQ.

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. | |||
