Hi there, I recently built myself a gaming computer and paired my year old lenovo mouse and keyboard combo with it. Just recently, the mouse pointer stops moving (which is the most annoying thing in the world in the middle of a game of StarCraft 2) and the keyboard does not detect keys when I type them. I have had to press the key multiple times to get it to register. What I want is a sub-$30 keyboard/mouse combo. Wireless is preferred, but not required. I don't need all the programmable buttons you see in like Razer peripherals, I just want reliability so i won't have to buy a new mouse again. Does anyone have any suggestions?
