New Build problems

[TobyW]

My specs are as follows.

i5 750 @ 4GHz Stable
8GB 1600mhz Ripjaws DDR3 Dual
5870
Gigabyte P55 UD5


My problems are as follows....

USB problems, when i attatch a USb device, such as a memory stick, my keyboard will stop working. HOWEVER, this is only through my USB extension cables. If i attatch the USB device to the front of my case, it works ok.

Large mouse pointer. Usually happens after exiting a game. However, it does it when i start windows up now and again.

Any ideas?

Is it a USB hub you are talking about? If so have you tried connecting the keyboard through the same hub as well as your other device?

no hubs. All devices connect straight to an individual USB port on the motherboard or the front of my case.
