Keyboard and Mouse doesnt respond

[shan]

heres the thing

i start the computer sometimes it all goes nice then after some times a wierd noise comes from the pc and the keyboard and the mouse gets stuck...
sometimes it happens at the start itself.. keyboard stuck and i cant select which os to boot
there isnt a problem in keyboard or the mouse as i tried it on the other computer and its working right..
any ideas about whats wrong

[tangomouse]

Faulty keyboard controller perhaps! wich is down to the mobo

[hellnoire]

I was thinking dirty contacts myself, which I suggested to him... not sure if that's the final problem or not though

[Alboguy]

Maybe a MOBO problem...

first take some compressed air and clean out you case and all the connections on the back of the pc. double check to make sure not prongs are broke.
O and what type of keyboard and mouse ar ethey usb or ps2?

[shan]

ps2
i think there is something wrong with the motherboard....
the beeps are sounding like there failing

[Lenogris]

Hmm do you have another keyboard to try? as the first post stated good chance you mobo is bad. what kinda beeps do you get durning post? and what brand of bios do you have?

[shan]

it was a motherboard problem... and the keyboards work fine...
the sound was like a failing beep
