POST issue on Shuttle G5 models - check setting of jumper JP4.

  1. Most of the time when your system won't post it is because the J4 jumper pins are loose and losing connection to the motherboard. This means, when you turn on your computer it won't show anything on the screen, known as the No-Post issue.
  2. To fix this, please unplug the power cord first, then open the case and remove jumper J4 from the motherboard and put it back in place upside down.
  3. Now please restart the computer and the BIOS screen should appear.

Please flash CR40 firmware to G7V9 or disconnect CR40 & uninstall nVidia IDE SW driver. Download

There are some limitations with Athlon 64 socket 939, the DIMM 2 slot in the SN21G5 has limited functionality when only one RAM module is installed. Note, that when two modules are installed, this RAM issue disappears, and the SN21G5 functions completely normally in dual-channel mode. For this reason we suggest that you install any RAM module into the DIMM 1 slot first, reserving the DIMM 2 slot for the second module or future upgrades.
