Long story short... had a power outage yesterday, now my computer won't start.  I press the button and nothing happens.  There's a light on PS that's blinking kinda fast when it's plugged in... slower when I unplug the cord.  I tried unplugging... and holding the power buttin in for 5 seconds as a lot of sites recommended but it didn't work.  I flipped the voltage selector back and forth and that didn't work either.  It was plugged into a surge protector.  
It's HP/Compaq machine that's about 6 or 7 years old.  Is the PS fried or is there some sort of reset I gotta do?
