I think my motherboard is fried :/ not sure though

[Saz2123]

Hey so a few weeks ago my psu went pop. Like literally popped now this happend once before but I replaced the psu and jt was good
Now this recent one popped and once I had the money I bought a new one
Anyway I set it up and stuff but my computer wouldnt power on..
And I'm 90% sure I plugged everything in correctly. Anyhow I was looking around and noticed that the litle lithium battery in my motherboard had a little burn on the bottom middle so I thought my motherboard was fried. But then I noticed that there was a little green light on my motherboard was on meaning it was getting power from the new psu so I'm really confused as to whats happend and how to fix it

Please help
Thanks
