MotherBoard Asrock 970 extreme4 burned

[ezio66]

hello to everyone
The heat this summer caused an overheating of my PC and after hearing a burning smell was no longer on again.
I tried to remove all cards installed and try to power the motherboard. The result was that if I enter only the 24-pin connector ATXPW1 seems to light up but as soon as I post too but unfortunately when I insert the 8-pin ATX12V connector the card turns off and will not turn back until they I remove again the ATX12V connector.
Unfortunately I do not have available the schematic and then I can not understand which component burned
Can someone help me?
Thank you in advance

If you're sure it's the motherboard and not the PSU and it still is under warranty, then you could RMA it. Check the VRM components that are hidden under a heat sink.

hello Ghislain
thanks for the quick response
Unfortunately, the motherboard is no longer under warranty, but this is not a problem because I am an repair technician and I have'nt problem to repair it alone if I had the wiring diagram.
Unfortunately, the power supply was burned, but I already repaired
A greeting

but I hope that someone in the community to help me in this.
I've done a visual analysis to check if some component proves burned or damaged but unfortunately nothing
Anyway thank you for your support
