For me, the solve was replacing the Power Supply. I had an Antec 550. Now i have a Corsair 750 and its running awesome.
I almost got scared at first because it took about 10 seconds to get to the "bip". Glad i waited rather than go nuts thinking is not the power.
Oh, and wanna hear the good news? The Windows 7 64-bit Pro that i had installed on previous system is running on this one too... Time saver.
Good luck everyone.
