Apparently there is something confilcting with something ot the ps2 ports are faulty! We'll need to find out! Try plugging up your system without the video card but the ps/2 devices plugged in! (we don't need to plug up hard drive, so plug them out if they are plugged in) When the system comes on(after your hear the POST beep, if the system speakers is plugged up to the motherboard). Try pressing NUM LOCK or CAPS LOCk to see if the light come on and off. If they do that means your machine is responding with the PS/2, if not then you need to find a PS/2 expansion adapter ot use a USB Keyboard and mouse! If you do get a response that means your ports are working and there is probably a confilct with your Video card! In that case, I assume you've already reset the cmos(if you haven't then do that). Also if you have an AGP port try an AGP Card, if you were using an AGP card try a PCI! Well the USB keyboard more than likely will work! try these out and get back to me! regards, babb

Keyboard stopped working

http://www.ascendtech.us/emachines-kb-0705-ps-2-keyboard-black_i_kbdemkb0705bps2.aspx

Things I see here.
1) The second Keyboard you plugged wasn't any good either.

2) The PS/2 port for your keyboard on your motherboard, isn't any good anymore.
Computer off, plug it into the Mouse PS/2 port, and use a USB mouse.
BIOS will reset the I/O address for that PS/2 port, and set it for the Keyboard, when the computer is turned back on.

You may have to;
A) Turn the computer off
B) Unplug from power.

C) Press the Power On button in, and hold it in for a count of 10 seconds. Let go of the Power On button. Do this same procedure two more times.

What you are doing is draining residual power, clearing CMOS Error Codes, and resetting BIOS back to the factory default settings.

Keyboard plugged in, USB mouse plugged in, plug the computer back into power. WAIT 1 minute, turn the computer on.

Still no?
Motherboard replacement.

You didn't unplug the old Keyboard, WITH the computer on, and plug the new Keyboard in, did you? It isn't a hot-swap device. The computer must be off when unplugging a mouse, or keyboard.

For additional questions please post in a Comment.

I have a Dell PC and I unplugged the mouse and the keyboard temporarily to clean it. When I plugged them both back into the tower and turned on the computer, neither one worked. I tried to restart, shut...

To try to resolve the issue:
1.) Will a different keyboard and mouse work (PS2 is the name of these connections)
If they will, damage to the keyboard and mouse is likely)
2.) Will a usb mouse and keyboard work?
If they do, then the problem is with the controller on the mobo, unlikley but MAY have been casued by static.

If the USB keyboard and mouse do not work, you have some problems with the motherboard

Try switching off and unplugging the computer, remove the coin shaped BIOS battery and plug in the keyboard and mouse, wait 2 minutes or so and put the battery back, replug in and power on, see if the bios detects the keyboard and mouse (you will see the bios screen flash up a message). If the computer does nOT detect the keyboard and mouse it will (or should) flash a message on the screen saying "no PS2 keyboard or mouse detected".

If this fails to detect the mouse and keyboard and you get no message or beeps, then there may be damage to the connector ports.

If you can get a USB keyboard and mouse to work, use them, Effecting a repair to the motherboard will not be a viable option

Acer desktop mouse,keyboard not functioning, monitor also not wor

If there is no display on the monitor, then your computer is not sending a video signal to the monitor.
This could be caused by a bad video card or some other hardware problem. I would open the case and disconnect all the devices (hard drive, CD, etc. Leave only the CPU, memory, and video connected. You could leave the keyboard and mouse connected too.
If your computer then starts, you can start to add devices (after turning the computer off) one at a time.
If this doesn't work, then you are looking at replacing the motherboard or just the video card if that is possible.

Wireless mouse and keyboard issues

If you have both sets of keyboard and mouse plugged in, turn off the computer and remove the old mouse and plug in the new mouse. Reboot and if necessary use the keyboard to login. Once windows is loaded let it detect the new mouse and then shut down again. Take out the old keyboard and reboot. You should now be able to use both new pieces without problems.

Keyboard & Mouse

Hi,
Make sure that the keyboard wire is plugged in to the keyboard port and mouse wire is plugged in to the mouse port. Remember that you need to restart the system once after you plugged into the motherboard. if that doesn't work then replace the keyboard / mouse and check. if same thing is happening then there is a problem in your motherboard. Thank you.
