Sounds like you may have fried your motherboard. A bad fan alone shouldn't cause it to stop working. At least not unless it had a short that effected more than just the fan.
The only way to know for sure is to open it up and look.
If it is under warranty, contact the manufacturer. If it isn't, then you can try and do the work yourself. If you feel comfortable doing so. Or, take it to a local tech.
