RAR package for the ASUS B75M-A, an Intel B75 micro-ATX motherboard with an LGA1155 socket for Sandy Bridge and Ivy Bridge processors. The archive is 313 KB and the name gives no detail of its contents. A boardview or schematic of this size is the likely payload. Use it to find shorted capacitors on the VCORE line, trace the 3VSB and 5VSB rails, and locate the SPI flash for reprogramming. Check that the revision printed on the board matches the files before relying on them.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @boardview. Enginerys does not host this file.
