After power went out in my home, my computer would not turn back on. My computer is connected to a surge protector. I figured i may have blown the computer's power supply. There was a flashing yellow light on the power supply, not sure what this means. I replaced the power supply, but still won't power up. I also have noticed a tiny green light on the motherboard next to where the 24 pin power connetion is plugged in to. Could something be wrong with my power botton on the front of the computer, or is this something more serious like a fried motherboard or proccessor?

Is it plugged into a surge protector? When the power comes back on to a lot of residents at the same time, a power voltage spike occurs that can damage electronics. All items that have any electronic circuits, need to be protected by a surge protector. Surge protectors do not protect against lightning strikes.
1. Check the power cord is plugged in properly by removing it and replacing it. 2. Try a different outlet on the surge protector.3. Most surge protectors have a reset button, try resetting it. Is the sound bar the only device plugged into the surge protector?
Check the main fuse in the power supply, the TV also has small surge protection devices (MOVs) installed after the fuse, any surges the come along and big enough will cause the main AC fuse to blow. When you surge protector, EVERY connections must go through the surge protector, for example, the AC cord of the TV is connected to the surge protector, the cable connection did not go through the surge protection, the surge then can get to the TV through the cables.
try removing all power cables of your computer that are connected to the surge protector. reset the surge protector. wait for about 5 minuets before you turn on the surge protector. then plug all cables that your remove from your computer the turn on the computer.
1. Make sure the the surge protector is securely plugged into the wall. Test this by plugging in a light / lamp to it, to make sure it's working. 2. Make sure that the surge protector is turned on. 3. Check to make sure that the power cable from the computer to the power surge protector is securely plugged in. 4. Check to see if the computer will power on now.
5. If this still isn't working, remove the power strip/surge protector and connect the computer directly to the wall.
6. If this STILL isn't working, try plugging your computer into a different outlet in the house to see if the outlet in your home might be bad.
6. If your computer STILL isn't powering on then I'm afraid the worse has happened, which is one of the following issues:
1. Bad power supply (they are cheap, around $20-40) 2. Bad motherboard (they are sort of pricey, around $50-200) 3. Bad CMOS battery (they are cheap, around $5-10)
I can fix all of the above and order parts for all of the above, if you are in need of parts.

Sounds like your power supply may be shot on your computer. You can get a power supply tester and check it. Not sure what to do about the printer. If you had a surge protector in between your computer and ac. Plug the computer and printer back in to the AC outlet directly and see if that helps. Hopefully only your surge protector is damaged.
