Why does my computer not recognise my keyboard?

Question

A couple of days ago, something in my power supply blew. It blew when I turned on my computer and after I heard it blow the computer automatically shut off. I turned off the power to the computer and opened it up. I could smell that the pop had came from the power supply because I could smell something that had burned inside the power supply. I put the cover back on and tried to restart the computer. It turned on fine, but it did not recognize the keyboard even though it was still plugged in. I bought a new power supply today and installed it but the computer still doesn't recognize the keyboard. I tried a different keyboard but during startup it still doesn't recognize the keyboard. I would like to know your thoughts on this problem and if you think it is repairable and how much you charge for repairs. Thank You for your support.

Thank you for your question. There are two possible things that may have happened. First, the drivers, setup information, system files etc. for your keyboard could have been deleated for whatever bizzare reason when your power supply failed. I would try reloading them. Second, when the power supply failed, it could have damaged your motherboard, probably the keyboard port. If that is the case, you would need a new motherboard. Most computer repair shops charge a fee just to diagnose this problem. The charge may be between $30-$40. Then they charge by the hour to fix the problem. Then you are looking around $70 per hour. A good repair shop will call you to let you know what is wrong and if it is worth fixing and how much it will cost. Hope this helps you out and good luck.
