Mouse freezing

I have a Logitech MX510 and love it for gaming. Problem is for the last few weeks it has been freezing, but only for around a second, which is very annoying in games, i cant even click whilst it freezes. When it freezes though the red light will stay on, but very occasionaly it will stop altogether with no light and will need to be replugged in. I have reinstalled drivers, plugged it into other usb ports etc and still it is freezing.

I know people have had problems running ventrilo and using there mouse without any troubles, but I need to use ventrilo when playing CS and if you cant guess thats also when i need my mouse to work without freezing...

 

I have problems with voltages on my pc if that could mean anything,
VCoreA : 1.66V
+3.3V : 3.01V
+5V : 4.62V
+12V : 11.70V
-5V: 2.85V
-12V : 1.71V
+5VSB 3.18V
+VBAT 1.55V

could it mean there isnt enough power going to my mouse sometimes?
