Hello. 2 days ago, I was uninstalling Kaspersky Internet Security, after reboot mouse and keyboard don't work (kb is ps/2 and mouse USB) and after turning off the PC with power button, keyboard was still on, and I could turn on the computer with any button on keyboard.

Never had something like that.

Keyboard works in Bios. I disable option to turn on the computer with keyboard - that doesn't change a thing.

First what i did is put CD with win xp turn on recovery consol and from there I replaced files (sam,security,system,default,software) from restore folder with date before this issue, but that dosen't fix my problem. mouse and keyboard still don't work, which is odd.

Then I repleced the driver i8042sys, but this also do nothing.

Then my firend told me to repair partion with windows xp by windows xp CD I did that and during instalation of devices i've got an error "Failed to install one of the core component which may affect driver functionality The most recent driver that worked will now be restored" and I have to click OK.

Thing is, in this installation mouse and keyboard also don't work and I can't finish repair because I can't give a command to proceed. I've check different mouses and keyboards with USB and PS/2 ports, also check all the ports. Nothing.

On my other hard drive I have win 8 consumer preview and in this system keyboard and mouse work. Why I think this is the issue with motherboard is that after turning off the pc, kayboard was still on. Lights etc and I could start computer with keyboard.

Before this issue, when shouting down the pc, keyboard was also shouting down. That explains why restoring registry files from date before malfunction and switching keyboard driver (i8042..sys) didn't fix it. Windows didn't show any errors.

Sad thing is, that by trying to repair partion with xp win 8 dissapeared from boot menu, also hard drive with win 8 (IDE drive) dissapeard from BIOS. In order to boot win 8 I had to dissconnect the hard drive with xp. Now i don't know what to do to boot win 8 and that other hard drive with xp in order to at least have acces to my files (this hard drive with XP Sata drive was my main hd, this with win 8 is old IDE drive).

But I think if i can change something in motherboard that leaves keyboard on after shouting down the pc it will fix the issue and let finish repair of partition with windows XP.

It have to be motherboard cause what else could leave kayboard on, when pc is turned down ? Dunno.. have chaos in my head. I spend many hours on google, and find somebody with simmiliar problem, and in that person cause.

Even formating the hard drive didn't fix the issue. I don't know much about working of the motherboard i assume it have somewhere section which is resposible of manage the power (which cause the keyboard to be on after shouting down the PC, add to that XP which possible can't manage that kind of behavior and shouting down controls.

I hope you can help my in some way and that my english is good enough.

Hello, mehow89 and welcome to TSG. :)

I've taken the trouble to put your post into a certain paragraph structure, lest any reader gets as breathless as your original version sounded. And just gives up after reading the first 10 per cent.

I think your English is fairly good and should now be more easy to decipher.

Although "shouting" down keyboard and PC is rarely a solution and merely annoys the neighborhood.;)

But readers may now also understand that you meant "shutting down":)

Please be patient for reply.

try booting to recovery console on cd and logging in to your installation then type chkdsk /r and press enter and let it finish then if you feel safe and if you dont have data on their that you need just fresh install windows if you need the data off go to and install that on another computer grab a cd and download this
off of
you might be able to just click link once that is done open imgburn and burn the .iso file you downloaded to cd once done you can boot to that cd by sticking it in to the broken computer and pressing f12 at startup and pressing enter on cd rom drive to boot to the cd now you should have a screen with stuff on it and you should just press enter and it will boot in then you will have a desktop after a while and you could use that to copy files off of your computer
Have Fun
