Alright, so yes, i'm posting already yet again

This time when i turn on the computer I have no keyboard functionality. (On one of my other COMPUTERS obviously). I just switched the motherboard, cpu, and power supply, but i did have it up and running. I reformatted Windows, had it working for a while, and then when i opened it up again to fix a RAM problem the keyboard stopped working.

I've tried unplugging it multiple times, i've tried other keyboards i know work, but nothing works. No lights or anything. ALSO, for a while it was going into windows, so it even recgonises it has a keyboard, it's just not working... Now it's not going into windows though, because trying a suggestion that was given to me it now requires me to go into CMOS to fix something, except of course i can't. One last thing with it. Right before it started happening it said "found new hardware", it was the keyboard, and it tried to install drivers for it but couldn't. I've never had to install drivers for this keyboard, it's not a fancy one.

So any ideas of what's up?

I was thinking about buying a new keyboard, so i could just get a USB keyboard. I want to make sure that it'll work though, and also it would be nice if i didn't have to limit myself to USB boards.

Thanks as alwaysYou can buy a usb key board adapter. If you can go into windows? try a system restore. Even before i buy an adapter it would be good to know if that will solve the problem, and i can't actually get into windows anymore because of a suggestion someone else gave me. It requires me to press a button on the keyboard, but i can't.

Also, new development. In the dark i can see that the keyboard lights are actually flashing. They're just not at full strength so i couldn't see them in the light. Also, they're just flashing, they're not actually on.You have a hardware issue and the only way to trouble this Pblm. is to 1st make sure all your cconnections inside case are secure if so you are going to have to start swapping out devices. You can also start by [with system off] use 1 stick of ram, cpu with fan connected ,video card connected to monitor screen. [only these ] turn system on and see if it posts,post to monitor.You can have the keyboard connected also and see if you can go into bios screen,refer to your mother booklet to see what key to use to get onto BIOSWell I already can get to post. My keyboard jsut isn't working so i can't hit the button to get into BIOS. As well as it requires me to hit a button to move on from post into windows, so without my keyboard working i can't move past postIts only a small$$$ amount to get a usb to keyboard adapter,i would do that and see the result?If you find you still have a PBLM. I would think its either the board or CPU.How old is this system & what board is it?Forget the adapter...they do not work with all USB keyboards.
Spend 10 bucks and get a PS2 keyboard / mouse combo...everyone should have one.
Even if it's stored in the closet most of the time...Whatever you decide on doing next is up to you? I said if the keyboard is ok & you still have the PBLM. its most likley the cpu or MBsorry patio, i should have made that clearer. all i have are ps2 keyboards.

also, xavier, i just REPLACED both the mb and cpu, and they worked fine. it's possible the PORTS messed up, but the board shoud be fine

not trying to be difficult, sorry, just want all my computers to work for once!Could it be that a pin has broken off in the port? Get a flashlight and a magnifying glass and give it a good look. If you replaced the mobo and cpu and the key board still dont work what does that tell youjj 3000
I took a look at the port, flashlight in hand, but i didn't see anything. I don't have a magnifying glass right now, but i got a pretty good look in there. Still, i'll try to find one and look again.

I replaced the keyboard and cpu before this happened. Then after having already used the computer for a while, the keyboard stopped working. Everyhting else with the computer is still working, just the keyboard isn't.

Here, i'm going to post what i did that's now keeping me in post. I did a google search and this is what came up http://www.techsupportforum.com/hardware-support/other-hardware-support/202090-keyboard-failure-boot-no-mouse-keyboard-functionality.html Now it's giving me some message about CMOS only it didn't fix the keyboard problem so i can't get there. Also, i should mention that i don't actually have a Dell Dimension 9150, i just figured it wasn't something computer specific.
