Computer doesn't detect monitor/keyboard

[TinStar]

monitors connect to video card in the pc. I removed my gaming keyboard and everything is working fine now. The only issue I am having now (which I was having before as well) is occasionally when my computer goes to sleep, I am unable to wake it back using keyboard/mouse so for me to get it working again, I have to hit the power button on the computer which will turn the PC on (but doesn't actually load the OS) and then turn the power supply off. Then once I turn the power supply back on and turn the computer on again, the computer wakes up and goes to the state it was in before it went to sleep (so all my chrome tabs are open and any programs I had running are still running...)

I physically checked for temperature issues and didn't notice anything being exceptionally hot and nothing looking burned or anything..
