    Not overclocking are you ?

    The checksum errors can mean the bios is corrupt possibly from a bad flash.

    You've tried already what I would do though just test some different RAM just in case. After that try flashing whatever is the current bios release again to the board if you really want to try get it running & hope that clears it.

    Got that a few times overclocking myself. Reset the BIOS to defaults or safe settings. Check your memory - that timings in bios match with spec. also voltage if that can be adjusted.
