<google>ENGELSK</google> Many motherboards are made with too cheap capacitors. After a while they start to deform or leak, and in the end the computer or power supply stops working. Capacitors in switch mode power supplies and motherboards needs to be low ESR types. These are expensive and that is why manufactures try to use cheaper models.
If you have a device witch has stopped working and the capacitors look like this picture there is a big chance that if you replace every capacitor with new LOW-ESR types it will work again. It needs to be LOW-ESR types otherwise they will blow again soon.
