Anybody ever heard of this problem before? Yesterday I tried to boot up my sons computer but it would not boot up. I unplugged everything. Bottom line: when the keyboard is not plugged in, the computer boots up fine. When the keyboard is plugged in, no go. With keyboard unplugged and computer running, I will plug in the keyboard, now mouse freezes and nothing works. I tried 3 different keyboards, same results, Any ideas? thank you

hi, hmmm sounds like a familiar problem i had with the port for my mouse.mouse plugged in compter wont not even turn on,unplug mouse no problems.eventually found out the port is screwed ended up going usb for mouse.do the lights stay on all the time on the keyboard even when computer is off?my mouse light on the optical mouse was always on even when computer was off.maybe the port is fried and you will have to go the usb way. keltik

Just a thought to go along with keltik's post. Perhaps a key on your keyboard is stuck down; try another keyboard. You could also try going into the Device Manager and removing the keyboard. Windows will reinstall the board during boot-up. sLLs

If, as you have stated, you bump into the same problem regradless of the keyboard, then it is clear that the keyboard is not the problem. If, as is implied from your question, the computer simply will not boot when a keyboard is plugged in, then it would be clear that it is not a software issue. The logical conclusion is that there is a hardware issue. Regarding the hardware, first and foremost it would probably be best to make certain that the pins in the keyboard input are not bent or touching one another (though this issue would only apply to certain jacks that are male inputs...) If there are bent pins and/or pins touching one another, this could probably cause a short which would freeze the system from operating. The next possibility is that a component on the actual motherboard (in the keyboard input area) has shorted. If you are familiar with electronics somewhat, just look around that area of the MB and see if its visible. If there is not clear indication of a 'blow' on the MB in the immediate are of the keyboard input, it might be good to look at the connections of the input to the MB- just to see if there might be something causing a short by connecting two soldering points. All in all, I believe most people would recommend that if your system is under waranty then you should have a replacement motherboard shipped out. If it is not under waranty, then you might try the following first (I cannot elaborate at length, but this is the general idea): uplug everything from the MB, except for the RAM and reset it (a jumper usually near the CMOS with indicator printing around it explaining various positions) Then 'turn on' the computer (it should actuall not turn on) After this, return the jumper to its normal position and try to power the system with the keyboard connected. If it works, then slowly add devices until you isolate what it is that may be causing the short (it is possible that the keyboard is simply 'the last straw' to another issue...) When you find the defective device, simply keep it out of there. However I doubt that this is the issue or will help the problem at all. Good luck, Larry
