I have an asrock z170 pro4 motherboard, avexir core 2666 ram, asus rog rx460, and a pentium g4400. i plan on bclk overclocking bty. i also have an old(er) coolermaster 450w psu that still works fine. i have a rosewill glacier 500m in the mail. my motherboard will not post. it turns on for a split second, then off for a few seconds then back on for a split second and back off! i checked everything. and cannot figure it out. due to a long story with newegg customer service i do not think it is the motherboard. i originally ordered an openbox pro4s. it did the same exact thing, i then requested a refund for this one. i doubt id have 2 seperate model motherboards in a row doing the same exact thing. i tested the coolermaster psu and it works fine on an older motherboard with an athlon x2. i can only think its the ram or the fact that the coolermaster only has a 4 pin eps. i doubt about the eps due to the low powered pentium. i am still a noob, just trying to provide info. please help
