Gigabyte 8TX motherboard documentation, revision 1.0, in a RAR archive of about 1 MB. The name carries no further details, so extract it to confirm the contents, which are typically a schematic in PDF. Use the diagram to trace power from the supply connector, follow the processor regulator, check chipset and memory voltages and pinpoint parts that are shorted or damaged. Confirm the revision marking on the PCB matches 1.0, as Gigabyte revisions can change layout and component values.
