Yes I have never killed a cpu either, after it shut down I noticed no smoke etc, no lights on mobo other than power switch lit, press it and the mobo LEDs flickered quickly then nothing. I suspected psu as its an old benching OP1000 so I swapped it for a good psu, still nothing but a red light shows on the psu (CM real power pro 620) . I swapped cpu and rams onto another EVO this one tries to boot, hdd spins up but mobo post stops at cpu with LED lit on mobo and no red light shows on the psu. I will need another 1155 cpu to confirm and I dont really want to buy one just to test these parts but it looks like Im going to be forced to. I did want to try a 2500K anyway so I guess this is a good excuse.

What do you guys reckon? Dead cpu?
