CX600 problem with motherboard

Hi all,



An year and 2 months ago, i bougth and built my PC. After an year the motherboard (ASRock B75 Pro3) died, i sent it back to ASRock and they sent me a new one. I used it about 2 weeks and it died again !!



So i wanted to know if perhaps the power supply (CX600) was the problem? Could the powersupply still be working and damaging the motherboard at the same time?



Thanks for your help,



Bye, BigDan.
