judging by your description, it sure sounds like it has to be the mobo. There’s really nothing else since you ruled out the hard drive (which woulda been my other guess. Can’t see the PSU doing anything like this).
you don’t need me to advise against doing a motherboard install with a different motherboard but same chipset with an existing installation…right? 🙂
From articles i’ve read about doing so (since even i yes have wanted to avoid reinstalling) make sure you uninstall all the chipset drivers from device manager before doing so, and cross your fingers. still, if you *can* a reinstall is definitely the best way to go.
