I have a Gigabyte P35-DS3R rev 1.0 with an e8400. When I clock it over 3.6 the mouse quits working. The mouse is a wireless usb mouse attached to a trendnet kvm switch. There is a USB to PS2 adapter on the wireless receiver that attaches to the kvm. When I use a ps2 or usb mouse plugged directly in to the mobo it works fine even at 4.3ghz. The obvious solution is to get rid of the KVM but I really need it. I'm open to any ideas. Thanks
