Problems with ports on my monitor

[Spacewolf]

ok i had my mouse and my USB wireless stick stuck into my monitor but for some reason it started mess up and my mouse would die (the laser ligth at the bottom goes out) and my USB stick lost the signal after a few seconds it would reconnect so moved my usb stick and now thats fine but the mouse still keeps going out. So i was wondering whats going on and how to stop it. I need this because my USB stick doesnt work as well as ussual as ive gone from basically Zero lag to Constant Yellow with large ammounts of Red and some sort of symbol that i belive means super lag that appers above the lag symbols.
