Annoying and Mysterious Keyboard and mouse problem

So, here´s the deal. I had to change my motherboard from Msi neo k8t to k8n.
After that I successfully installed Windows as a repair-installation. I noticed very mysterious problem: When I boot my pc, the keyboard and mouse are frozen, like they aren´t connected to machine. But when I press the reset-button, forcing the system to boot again, it boots, and now the problem is gone! This is really annoying, cuz everytime I have visitors in my house, I have to warn them: Use reset after 1st boot...
The continous restarting makes me running on the walls , so if someone can help me, I´d very pleased

 

XP? Try going into the device manager. Find the keyboard & mouse. Right click on them & uninstall them. Reboot Windows will pick them up & reinstall them.

Any good?

 

Uninstalled both drivers, reboot, result: No good

 

It's possible that the mother board did not like the OS being repaired. It might need a format. Wait & see what others come up with.

 

I sincerely hope, that someone can solve the problem..

 

have u tried another keyboard?,fidderling with the bios settings turning unused things like serial and com ports,checking the device manager throughly,for any conflics.
err checking keyboard and mouse cables

 

I have disabled these things: Onboard serial port 1 from 3f8/irq4 to disabled
Onboard parallel port or something to disabled
Bios support for usb-mouse is also one of the settings that I disabled, cuz I have both devices in ps/2 port.
Is paraller-port = COM-port? I don´t think so, but can someone tell, where is the COM-port setting in bios?
Device-manager found no conflicts, but can you trust to microsoft

 

You might try running the system file checker. This will reset your system files to a known good state, extracted from the Windows installation CD. To do so, please do the following:

1. Insert your XP installation disk
2. Hit windows key + r (or click start --> run)
3. Type 'sfc /scannow' (without the quotes)
4. Press enter (or click 'OK')

The system file checker (sfc) will now run. Let it run through and restart your system.

 

sorry serial port is com port, i meant parallel

 

Manic Miner:No problem
But, If I run the System file checker, is it nearly 100 % sure that I won´t loose any of my files, like my important docs etc.?

 

Finished system file checker, restart, Result: no good
Keep up the spirit...

 

how about backing up all your documents and doing a complete fresh install from scratch, i know its slightly extreme and annouying.

have u tried uninstalling your keyboard and mouse from device manager and rebooting,

 

I´ve tried it, result: no good

Next thing that I will try is to flash my bios with a new version, but after that I´m out of ideas....

 

*sigh* I don´t if it´s Murphy´s law or something, but yesterday I flashed the bios, it was 100% successful, until the pc booted itself after flashing: the pc doesn´t boot anymore.
So, the next step will be straight forward to the maintenace..
