As good at soldering as you may be odds are the damage is done to internal traces and not to external components. Plus most motherboard, even as old as that one, utilize wave and micro soldering which requires precision machines as any heat can greatly and very quickly damage motherboard components.

You will probably be best off getting a new board/system.

Thank you for fast response , but I would like to try to repair this motherboard because right now it is defective anyway.
Can you tell me where to look for a malfunction on board ?

If there was smoke from around the second PCIe slot look for burn marks. I would honestly bet that the smoke came from under the slot and was a trace in the motherboard layer itself and not visible.

Motherboards use multiple layers to be able to route all the traces needed to connect everything. If it is a trace its irreparable as I don't even know of the tool required to remove a layer.

You can also look on the back side of the board for any damage marks.

Thank you very much for info, if I put PCI USB card would USB work ?

So long as there is no damage to the traces for the PCI slot yes. But you mentioned it freezes after some time which may still occur. You could try to disable the onboard devices such as the one you plugged into but that may not fix the freezing issue.
