Keyboard affect the system boot???

[J-Fire_Man 0]

I just recently had a weird error. A very stupid small lizard (I don't know what's the english for it, lol) is nesting in my power supply and ofcourse she won't last long in such place. Then, I removed my power supply and clean it. Then the weird error occured.

 

My computer seems to be running but not data transferred to the monitor and the speaker beeps 3 times, which ussully means there is an error with the RAM. After trying to find the source of the error, I found out that the keyboard is the one that caused all of the problem. I have changed it with a new one and my computer works fine again.

 

My question is, how can a keyboard interfere the system booting process so much and causing my computer to stop booting and make the speaker beeps 3 times??? What I know is we still can enter the OS even with a broken keyboard or no keyboard.

 

If anyone know how can this thing happen please tell me. I can't just leave a computer error without knowing how it happens.

Maybe this may help answer your question but it seems like this isn't a new issue.

Wow, thank you fenring this really helps. I only know 3 kinds of beeping code.

 

It actually beeps 6 times, but the interval between the first two beeps and the next beeps is quite long so I excluded the first 2 beeps.

 

If I include the first two beeps then the beep codes might describe the "Keyboard controller Gate A20 error". But what kind of error is this? Gate A20? :?

Gate A20 errors are with the keyboard, which this page explains.

I never thought that keyboard can affect the system badly, now I understand, thanks for the information fenring. Maybe I should buy a nice logitech keyboard later.
