Thanks Fishtown, the ends of the copper were black and flaky and 'carbonised' and fell off when I moved the board. One other question that would be helpful to educate me - the Medion 250w PSU has a 4 pin CPU connector and the motherboard has an 8 pin. Can I upgrade the current PSU to something higher wattage with a GPU plug in order to use a GPU with the PC?  Is it OK to connect an 8 pin CPU power plug (most PSU seem to be 8 pin) to the 8 pin on the motherboard. The processor is i3 10100 and I'm not planning to change it, I know it is lower wattage and only needs a 4 pin connector but will using an 8 pin connector be OK?   Most likely I will replace the motherboard when I can afford to as I am not skilled with soldering / repair.   Thanks Again 🙂 ...

Hi Fishtown, thanks for the quick reply, a few questions spring to mind:   What kind of things can cause overvoltage and this type of damage? What is the conductor track at the edge used for? ... because ..... The board is working fine now (at least it appears to be) since I removed the copper strands and there is no short - is the board safe to use or should I replace it?   Thanks again 🙂     ... View more
