so my mac mini was working fine up until one day i try to turn it on it boots up normally but as its loading some start up programs i have it shut off by it self
upon trying to boot it up again i got nothing no lights no sounds
apple said its the motherboard or the interconnect board they replaced the inter connect board with no results

the motherboard shows no signs of being fried i tested the power button with a multimeter
i don't think its the motherboard problem i think it could be the proccessor but not 100% sure any1 had this problem?
