Let me just clarify:
You changed:
- Motherboard
- CPU
-Left harddrive as is
Since the hardware you replaced the old stuff with is different, then i could imagine this could cause some problems.
When replacing hardware its best to stick with the same stuff, ie. intel for intel, amd for amd.
I would recommend you put back in the old hardware if possible and backup if you havn't already done so.
Then, you may either have to reinstall SME with the new hardware installed, or buy new AMD replacement hardware.
Cheers,
