i recently had a problem with my power windows an as i was trying to fix it i created another problem the car started before i replaced the fuses (fuse box inside the car) when i put the key in the lights pop up but as i turn over i get nothing almost like the battery was completely dead but i have already tried a different batt

my question is: is it possible i reset either the ignition or brain of the car? if not any suggestion on what it might be
