Good day all,

I built a new PC this weekend after I ordered some parts online.
CPU: i5 2500k
MOBO: Gigabyte Z68XP UD3
RAM: 8gb gskill ripjaws 1600mhz
GPU: EVGA 560 gtx ti DS OC

Everything is working smoothy after I formatted the PC (even a computer guy checked the bios and stuff, etc). I have Windows 7 64 bits ultimate.

There is a strange problem though.
My logitech mouse (I've had it since October 2008 which was worth $15 from Staples) cursor slows down after I plug in my Razer Megalodon Headset. If I remove the the USB for the Razor Megaladon and remove the USB mouse then plug it back in; cursor speed goes back to normal (not slow)

I need some help or inputs regarding this!

Thanks in advance.
