Microsoft Usb / Ps2 Wheel Mouse Problem

Hi everyone,

Haven't posted here for a while so I thought I'D do so today.

Anyway, I have Vista Home Premium on my new computer, which included an HP wireless mouse (which eats batteries like candy). So, I had to use my old Microsoft USB / PS2 Wheel Mouse. Now the problem I'm having is that the mouse keeps on going on and off by itself. I went to the device manager and it said it was working fine, and I also updated the driver -- to no avail.

Does anyone have the same problem? If you could be of any help, I would really appreciate it.

Thanks!
