Power supplies can cause some weird problems when they're going bad. I've seen a couple of them that would boot one system fine but not work at all in another good system. If voltages are borderline or fluctuating it's hard to diagnose, sometimes my PSU tester shows everything good but it still won't boot the system. Since your only clue is the voltage surge error, I would buy a new PSU, or borrow one maybe just to try out. Out of all the systems I've fixed, most were power supply failures.
