Quite possibly right, Jim. Hope you find one that works - I'd be inclined to go for an MSI or Asus board as manufacturers tend to fit them. I've had Gigabyte boards that were iffy from the start, but the only two MSI boards I've seen go faulty were helped to their demise by their owners...

The first occasion was an Advent PC that was overheating, so the owner decided to transfer the bits into a bigger and better cooled box. Very laudable... except... when fixing the board to the metal mounting plate, you really should use the plastic stand-offs!! He couldn't understand why I burst out laughing and said I knew exactly what had gone wrong... good job he was a mate!

The second one was a board in an HP that was still working, just... the owner had been doing some upgrading inside, and somehow had broken some of the larger electrolytic capacitors off! Hamfisted or stupid... or both?!

Toodle-oo!
