Can't seem to figure this one out and the problem is starting to occur more frequently. Have a P4C800-E Deluxe Rev 2.0 thats connected to a wireless Chieftec Keyboard/Optical mouse. The receiver is plugged into both the keyboard and mouse ports on the motherboard. During normal operations - system is up and running there never seems to be a problem with either the mouse or keyboard but when the system is put into Standby mode and left for periods of more than a few hours, pressing either the mouse or keyboard will not cause the system to wake up.

Tried the following without any success to get the back up before completely powering off the system (turning off power supply)

1. Pressed the power button on case - caused the system to wake up but keyboard and mouse weren't functional

2. Resync'd the mouse and keyboard - still no go! Also the activity light on the receiver does not flash when a key is pressed or mouse is moved.

3. Rebooted machine - this is where its a little strange - Bios returns no keyboard found and will continue to boot.

4. Powered off system and unplugged keyboard/mouse and reattached. Restarted without any problems and keyboard/mouse were again functional.

5. In one instance when I had another failure I opened the mouse/keyboard and receiver and unplugged the cable connector to try and force the receiver to startup thinking that the receiver was failing. When I reattached it its lights all lit up as it was booting but it still didn't work.

My question: When a mouse/keyboard is unplugged or a connection is lost will the motherboards ports just stop working until a repower or will they poll until some is connected to them? My thinking here is that there is some problem with the receiver that makes the motherboard think the mouse/keyboard has been unplugged.

Finally, with the information that I provided do you think its the motherboard or the mouse/keyboard receiver. Returning the motherboard and getting a new one won't be a problem since I can get a swap through Newegg as its still under warranty. The receiver's internals look pretty bombproof but the board does contain a few capacitors and IC's that I guess could fail.
