Without a picture of the scratch, I can't a: narrow it down on the motherboard and more importantly to see whether the damage is bad...Bottom line, you should try at start your PC to see whether everything is okay any way as the damage might..I say might, be superficial and everything will work..If it does work, then do a couple of tests, like gaming, Aida64 load test and make sure it runs through the tests...If it does, you are okay...
