I am having issues with a PC that is giving power surge warnings during start up. I have tried three different PSU's, 2 of them new, ranging from 600 to 680 watts. Upon turning on, it will power up for a second, lose power for a second or two, then power back on and give a surge warning during boot sequence. The only thing I can think of is the motherboard is faulty and causing surges. Since the mobo is an Asus, another possibility is that the built in surge protection is giving a false positive, forcing the psu to power down. After turning off the surge protection, there are no issues during start up and the computer will go into Windows. Should I be concerned that the mobo may be going bad or that turning off the protection may risk frying the components.
