Replacing the old PSU would require a rubber mallet or sledgehammer - it's a different socket type.....and the "old" one is in the trash (unfortunately).
Graphics cards exchanged - identical cards in this machine (Deep Thought) and the upgrade/new build machine (Deep Green) - consecutive serial numbers.
The graphics card that was in the new build is now happily running in this machine - no pioint in swapping them back.
Graphics card that WAS running in this machine, was put into Deep Green - 3 minutes 27.
Tried a reboot and alt/F2. Took me to a page entitled "EZ Flash BIOS ROM Utility B327"
It went on to say "FlashType: PMC Pm4GFL004T LPC/FWH"
Current ROM
Board M2n-SLI Deluxe
Version 1400

Alt/F2 didn't display a clock, so wasn't in a position to check the time.
Will try again later when I get my instrument approach stop watch out of the car (yes, I do still time my approaches - I'm old, you see).
