new to forums having problems with 95

Hi guys I just bought a 95 lumina for 2000 it has a brand new transmission and everything was going fine until this morning I parked it 2 days ago and left nothing on that i know of now it wont start it kinda turns over quite loudly i might add but only for a second then nothing i know nothing about cars I'm going to try and jump it when my roomate gets home but do you have any ideas?

Sounds like a weak battery or dirty loose cables, try jumping it then have the battery tested,.
