I've built a p.c. using a GA-EP45-UDR3 rev 1.1 motherboard, Q9550 processor, 4GB RAM and GTX260 graphics card. My operating system is XP Pro SP2. BIOS is latest version F9
All appears to be well except...
When my mouse - MS Wheel Mouse Optical USB - is plugged into a USB port (or PS2 port using adaptor) and keyboard is plugged into PS2 port, the mouse will sporadically lose power. I can temporarily correct this problem by plugging it into a different USB port but then it happens again.
Occasionally the keyboard will also cease to function.
The problem, sporadic power loss to mouse or keyboard , will happen when I boot to a DOS CD-ROM, as well as when I boot to Windows XP.
In the BIOS Integrated Peripherals setting, I disabled USB keyboard, USB mouse and USB Legacy HDD. As long as I have both mouse and keyboard in the PS2 ports, the above problem goes away, but...
Is there anything I could try to allow trouble-free usage of a mouse in one of the USB ports?
