On my freshly-built PC with a Logitech wireless keyboard + mouse combo, sometimes the keyboard will stop responding to inputs. Thinking this was a problem with the keyboard itself I ordered a replacement keyboard + mouse combo. Unfortunately the same issue persists. Do you think this could be a problem with the motherboard or maybe a software issue? I know when I installed the motherboard (Intel DP55SB) I accidently bent the BIOS reset swich. Could that be causing it? Thanks.
