So I recently started upgrading my computer and bought half of the components; cpu, motherboard and ram, everything else is the same. Sometimes when I press the power button it will not post and get stuck on the orange dram led, I have to press the reset button 5ish times for it to finally boot. My question is could this be because I only have the 24pin and the 8 pin cpu power connected? I have left the 4pin cpu unplugged as my older psu didn't have the extra connection. Or could this possibly be a more serious issue? I've already tried re-sitting components but hasn't solved the issue so far.
