Thanks to everyone who answered - I got a 480 W power supply locally and it didn't help anything - but it's nice to have. Got another stick of memory from newegg and that didn't help things either so it must be the MoBo as it wil only load windows w/my old Buffalo memory - won't even take the new Crucial from newegg unless that's bad somehow. I don't know if FedEx vans out here go through EMP's on a regular basis, but it seems like the last few things I've gotten from newegg have had problems. At least the RMA policy is relatively painless
