SR 1222nx Compaq Presario SATA drive 512MB American Megatrends BIOS v2.54

When loading and detecting, system stops and displays a keyboard/Interface error. The mouse doesn't work either but O/S loads fine. I connected another ps/2 keyboard and it displays the same error. USB keyboard and mouse work well. I also opened the cover and check to see if the connectors were loose, but they seem fine. This system was very, very dirty from the inside, so I gave it an air spray blow to clean it. I also shot some air on the mouse and keyboard connectors just to make sure. I don't know what else to try. I don't know what to make of it, if it's in the BIOS or problably false contact on the soldering in that area.

I also checked the device drivers in Windows just to make sure, although I know the problem is not here.
Any advice is appreciated,

Thanksf

Keyboard drivers could be damaged/corrupt...I'd try uninstalling same (using Device Manager), rebooting...letting them install anew.

Well, the last thing I said was that I checked the device mgr , but everything's fine there. I am going to do that just to get it off my head....a last resort.

I have found information on this and everyone's saying motherboard issue at the controller chip or perhaps bad solder in that area. There is no answer for it that I have found.

I know want to forget about ps/2 and go with usb keyboard and mouse. The problem is that I need to disable the ps/2 keyboard error prompt that says to press F1 to go to BIOS. I haven't been able to find it in American Megatrends BIOS v2.54. I disabled the mouse, but I can't find the disabler for keyboard.

PLEASE HELP!

Unless you plug/unplug the connections a lot I doubt it would be bad solder traces. That's not to say the connections couldn't be bad. But I would check the BIOS settings first.
Just because Device Manager says everything is fine doesn't mean it's necessarily so

Solder under the mobo, not on the connectors plug ins ;-)

A solder bridge will almost always cause a failure right off the get go. This is what the industry refers to as an infant mortality.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

FWIW: There is nothing in Windows XP or any other version...that advises a user when a file is corrupt.

SFC /scannow is as close as it comes...and it only replaces the damaged system files after the fact.

Device Manager is an good indicator of some things, file/driver corruption is not one of them.

That would be a bad wave-solder job during the assembly phase and would probably still effect the connections on the mobo.
I would think if it's solder under the mobo it would ground out the entire board not just those connections. Plus, it should have never worked
Is this a new installation or has the computer been working previously?

I'm sorry for the late reply....

This system worked before. It just ceased to work all of a sudden. I have found reports with the same BIOS and HP system of this error.
This is a Compaq Presario SR1222NX.

PS/2 keyboard works fine on my other system. Problem's not the keyboard. USB keyboards works for entering BIOS. But the BIOS does not say anything about how to disable keyboard error or halt on error disable.

I was telling Hamluis , who posted here that I don't think is the mouse drivers. Legacy keyboard and mouse should load in BIOS w/o windows. Besides, when I load drivers with a boot cd, they don't work.
