No video, but PS2 mouse + keyboard works

Hi, please check your cables. And, let us know if when you turn on your computer LEDs flashes. If don't, please try it in any other computer (or laptop) you have. If it still not working, you will buy a new one. IF your keyboard have a PS2 connector (no USB), verify twice if you are using the right one (other one is for mouse)

Press the ID button on the receiver. LED will blink fast for a few seconds, then slower. Press the ID button on the keyboard and mouse (need a pen or something for the mouse button). Always works for me no matter which order I do them in. If receiver LED blinks whenever you mover mouse or hit key, it is receiving signal. (remember mouse sleeps after a few minutes and you have to spin the scroll wheel). If OS does not recognize on new computer, may be connectors. I had separate keyboard and mouse PS2 ports and had to use an USB adapter for the keyboard cable.

Have you tried rebooting once it is connected? Not sure if it makes a difference, but I know you can not hook up PS2 peripherals without rebooting.

It is possible the ports are going bad, But both at the same time is strange. I don ot know if you know that PS2 is not hot swapable, Which means that you need to completely shut down the system before pluging them in. USB, the system can be on. If you keep having problems i would switch to usb mouse and keyboard,,,Darren

Assuming you have checked in setup that the PS2 is turned on the other option is to re-flash the bios .
At some time someone switched the mouse and keyboard and started up the computer this can cause you to need to re-flash the bios most likely the keyboard chip needs to be replaced sorry to bring bad news .
Dell seems to have this problem yet the USB works is good where most modern keyboards and mouse are USB.
Purple is Keyboard if not color coded the closest to the outer side of case is the keyboard.
Good luck hope this helps you
PS. You may try setting the jumper pins to default the main board back to factory defaults then remove the jumper pin and leave off for first boot .When doing this be aware not to have the power cables connected to the server remove all power cords and the monitor . Prior to doing the first power up plug in the PS2 keyboard only then the monitor. Cross you fingers If you lucky your PS2 port’s will be working again if so shut down re install the jumper pin install the PS2 mouse.

Might be a defective keyboard. Check and make sure its compatible for windows vista but all keyboards should work with any system.. As well maybe the port on the computer is bad..

The PS2 mouse cable goes into the green port on the back of the computer. The keyboard goes into the purple port on the back of the computer. Let me know how it turns out..

the best solution is to get USB mouse since PS2 muuse is not working. and if you cloned the system yourself i suggest you take a look at the motherboar and youy will see a jumper labelled on the board PS2 keyboard and Mouse, place the jumper in the next pin. and try and see if it will work.

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

Did you go into the BIOS and set it to recognize the USB Keyboard after you reset the BIOS? Is windows not noticing it or the BIOS. You stated that it recognized the USB keyboard and then said that it did not.
What does all of this mean? USB keyboard does not activate "del" setup.

If it does not work, it is because you reset the BIOS and did not change the settings back for the USB keyboard.

I hope that I fixed your problem.
