Computer Fried

My computer is not starting up. I think it meant be my motherboard or something. I have the power light and the computing light. The computing light turns on ans stays lighted. My power supply is still good, bc when I plug in my mobiblu it still charges which runs though the usb. Daniel if you read this tell me if my thinking is correct. I was thinking about getting a 2 GHZ+ processor anyways. so it is good it burned out, but no comput till then.
