It just started recently, about a few days ago when I was playing Dota 2 and Tf2​
In Dota 2, I left click, and drag an item to my inventory. Randomly, it drops the item even though I didn't let go of Left click and messes me up sometimes.​
Tf2, I hold left click to draw back the huntsman, the arrow randomly lets go when I don't let go of left click.​

I am not sure what the problem here, whether its my mouse, or something is wrong with my computer.​
I tried to re-plug the USB for the mouse back into the computer. Additionally, I attempted to move it into a different USB spot, and I still have these problems. =/​
Can anyone help me?​
Do I need a new mouse already?​
 
If you have another mouse to try, do that. Connect a different mouse and see if you still have the problem. I'm willing to bet you won't.

Sounds like the button on your mouse got worn out. It happens.
 
What Gooch said. Mice die unfortunately :( test a new mouse to verify that's it.

If it's a high end mouse with drivers/software you can try re installing that.

Could also be the lead ~
What mouse is it afire?
You could also try uninstalling the mouse drivers and see if it works properly directly in windows.Drivers sometimes conflict, my deathadder had real problems with the latest drivers.
 
The mouse probably got old, and some naughty piece of dust jammed it. It happened to me before. The best solution is to go buy a new one, or just go to a electronic store to clean your mouse.
