First off a surge protector is of little help on power outage, they only "Protect" for High voltage spikes. You really need a UPS to protect for dropouts.
That said, You might try clearing your CMOS. I would turn the power supply off (On the back of the PSU. Depending on your MB, I would pull the CMOS battery and short the "Clear CMOS" pins, then replace battery. On some MBs you can remove the shorting jumper from the Pins (ie pins 1&2) and put jumper on 3&4 for say 10 Sec. then return the jumper to there normal position. Check your MB manual. If this fails, then try reflashing your primary Bios as it maybe corrupted.
