Hello! Recenltly, ( after installing windows 7 64 bit ) I noticed that my mouse stopped working, the cursor froze, but as I moved my mouse around the icons were flashing, and I could click. Basically the cursos is stuck but mouse is working. Does anyone have any solution how to fix it ? Im running quad core 2.40Ghz 275 GTX 4gb ram ( 3,50 usable) Thank you! Winhard.
