Windows 7: Left Click on my keyboard is clicking on its own

Left Click on my keyboard is clicking on its own

Hi guys, I'm on a Lenovo Thinkpad T530 laptop that's about four months old. I had a key pop off and Lenovo shipped me a new keyboard, so I replaced it myself. Since then, I've had issues where every 20-30 minutes, the left click will start clicking on its own (the key is not stuck, it is not a physical hardware issue).
Obviously, I figured that the problem came from the new keyboard (since I had the computer for three months with no problem before I replaced the keyboard). So I took the keyboard out, cleaned the inside of the computer and the pin connections with some compressed air, checked to make sure there wasn't any visible damage (nothing crushed, bent, or missing as far I can tell) and then put it all back together again. No luck, the problem persists. Just in case it isn't keyboard-related (doubtful) I am running a full system virus scan using MSE as I'm typing this, but I really think that there's something wrong with this keyboard. I uninstalled and reinstalled the PS/2 keyboard drivers and Synaptic touchpad drivers, to no avail. Are there any ways to determine the true cause of this problem and possibly solve it, or should I just call Lenovo and have another keyboard sent my way to try it out?
Thanks in advance :)

by "left click" you mean the keyboard arrows? If it's the mouse/touchpad buttons it's an issue of the touchpad.
Seems like a hardware issue to me as well.

Try running it the keyboard/touchpad disconnected using a USB keyboard/mice, if it has no issue, then it's a hardware problem.
