The drive may be going bad - or what is happening is a result of not reinstalling Windows after your motherboard swap.
you can frequently get away without reinstalling Windows when you change to a similar board from the same manufacturer, say from a Gigabyte P35 motherboard to a Gigabyte P45.
You changed from an Intel board to an AMD board. All bets are off. I'd rebuild your system on a new drive, using the old for secondary storage, then transfer the old files that you wanted to keep.
Then I'd wipe the old drive and retest. If it still fails any tests, discard it.
