Intermittent Mobo USB Ports and intermittent 2nd monitor....

[RhysMusique]

Hey,

Last night I was playing a game with some friends and they were complaining that my headset was kinda intermittent, after a while i noticed it actually disconnecting and reconnecting quickly, every 10 mins or so.

After that, my keyboard then turned off randomly. I should take this time to explain my set up.

 

Motherboard back panel______________Keyboard________Headset

                  |_____________Mouse

 

So i've got a Corsair Raptor K50 keyboard with my Corsair Vengeance 1500 headset plugged into it, all plugged into the back panel of the motherboard.

 

Thats only half the problem, i changed the USB ports i used and the peripherals have been fine ever since (knock on wood)

 

So today I was just browsing the web on my 2nd monitor whilst watching a video on my 1st monitor. The 2nd monitor flickered to a completely black screen but the monitor remained on, it does this around every half an hour, also I think i saw my NZXT cable LED case lights flickering in the corner of my eye but i cant be too sure.

 

Are these problems linked? I was thinking maybe a PSU problem? I'll list my full specs anyway to see what you guys think.
