Hey guys new to this forums have a bit of a problem I'll start off going over my specs... Intel i5 750 Lynnfield cpu, evga p55 ftw mobo, corsair dominator 8gbs ram 1600, asus gtx 750 ti and Ocz 650w psu. Got that out of the way, I realize that my system is pretty old about 7yrs with a couple upgrades ram, Gpu. Anyways I was playing Arma 3 after I overclocked it to 3.2ghz I remember right before it crashed the cpu was 48c.... So it won't turn back on it seems like everything has power to it but it won't post. My Gpu, cpu cooler, hdd DVD rom is running. I normally get a post code or something when I hit the power but nothing.. All the lights on the mobo are lit and and the evga logo is pulsing like normal.. What now?

That motherboard is a 2009 model. Try testing the CMOS battery with a load on it with a meter.

Overclocking failures can cause the PC not to boot. Try clearing the CMOS with power disconnected from the wall outlet.
