Question about ASUS P4P800-E Deluxe Motherboard

Will not boot with Keyboard and mouse plugged in

When my computer is rebooting I have to unplug the keyboard and mouse. The screen is black then after it sounds there are 3 shorts beeps or one long and 2 short, the hard drive light comes on and it boots to windows. I have no way of getting to my bios and it does not matter if the key board is plugged to the computer or not the internal memory does not display. I have changed my memory around to see if it was a memory problem but it still does the same thing.

Did you try removing each memory module individually... Instead of just moving them around.. because the error you are receiving is a bad memory error code.

Why can't I get a new usb mouse and keyboard to work on a very old Win98SE system that has working usb ports, but the old mouse and keyboard were ps2 connection?

You need to go to the manufacturer of both the keyboard and the mouse web sites and download the windows 98 drivers for both of them and install them.

My optical mouse KU916AA isnt connecting to the USB receiver. I have fresh batteries in it, but im not sure what button to push.


Go to this Microsoft article and read through: Microsoft kb838398

The steps here includes all troubleshooting you can use for response failures in wireless keyboard and mouse.

If the steps did not resolve your issue, try unplugging the receiver first and reboot the computer. Plug back the receiver and reboot again. This is to refresh the cmos of your wireless keyboard and mouse settings.

If all of these fails, your mouse is deemed defective.

Hope this works for you.

I recently installed the logitech mk550 keyboard/mouse combo on my desktop and it put my computer to sleep, now it won't come out of sleep mode and rebooting doesn't work, the computer stays asleep. Any...

Unplug the usb receiver as well as all other usb devices plugged in. Unplug your desktop from the power outlet. While unplugged, press and hold the power button for around 10 seconds to drain the power. Plug the power back but not the usb devices. See if it now boots up.

After installing drivers 4 wireless internet computer crashed and when rebooted it had no keyboard or mouse

Try disconnecting all external devices. Not the keyboard or mouse.
Re-boot unit and check your device manager for flags.
If found, remove them and reboot, checking each time a device is installed.
Hope this helps.
P.S. After all has loaded, then try your modem hardwire first. Wireless second.

System wont boot

Disconnect all devices except keyboard and mouse and master cd or DVD. unplug then hit power button. Plug back in. Hit power and hopefully you get to BIOS. If you do make sure you save the BIOS before you leave to start OS. Keep me informed and I'll keep checking your listing to see if its working or not.

No display

Are all the other LED Blinking. Fans revolving, etc but no power at the keyboard or mouse(if optical), then the problem is with the keyboard or one the pins of its PS2 connector might be bent. Try a different keyboard and see if the PC boots up.............sodeep

Cmos checksum error - defaults loaded

Ports are usually labelled - look carefully.
Try manufacturers manual.
Could be that keyboard is the larger 5 pin DIN socket (old IBM AT keyboard).

No mouse or keyboard power

There might be. Try the Keyboard and mouse on another computer and see if they work. By the way, are they wireless?
