The issue is dont see any error codes. The car just wont start up eventhough the battery is good. Its power windows also wont work. So I think I need to reset the computer. So can you please tell me if is it possible for me to reset the computer?

If the codes are current u cant clear them until the fault is fixed. Youll need a obd2 scanner to read the codes and replace the parts so you can clear them.I would remove and clean the cable ends. Load test the battery. If its turning over try spraying fluid in the throttle body does it start?

There is no reset that is going to correct a no start. I am just going to throw this out there, but have you checked signal to the starter?
