My tower would not turn on when I came home from a vacation. Possible power outage/surge destroyed it. I replaced the power supply, and now I at least get the fan's running, but at various speeds. Still won't turn on the PC. is my motherboard possibly shot?

Easy Answer, YES MB could be shot.

Heavy dust/lint buildup can cause problems in this area. Unplug all cables from the box, remove the side panel. Remove all accessory cards from the motherboard. Optimally, use a compressed air blower to blow out all of the lint to pristine condition. Don't forget to blow out UNDER the MB too. There is about a 1/2 inch space between the bottom of MB and metal case and lint here can sometimes short between wiring and cause odd power behaviours. Make sure you blow out all of the edge connector slots that the accesory cards plug into. Blow out the power supply as best as you can.

Wiggle all the power supply connectors. Oxidation/microdust can make for intermittent circuits.

Before re-installing accessory cards use the eraser on the end of a pencil to rub the edge connectors until they are bright and shiny.

Re-assemble and give it a try.

If still no start, A bad drive can cause no start and poor power levels. Temporarily install another bootable drive or try booting from CD.

Last but not least. Corrupted firmware on the bios will cause your symptoms. A little known secret of bios systems is that there is ADDITIONAL firmware on most MBs that will boot from FLOPPY and auto install a new bios. You will first have to download the bios update from manufacturer for your MB, then put it in floppy, then unplug hard drives and CD drives then reboot. If the bios re-installs you are ok.

If none of the above works it is time to go to pricewatch.com for a cheap MB combo.

Good Luck

Power too computer will not come after power outage


Check your surge protector, it may have tripped due to a surge in power.

If you didn't have it on a surge protector you could have blown a capacitor in the power supply. In that case replacing those is pretty simple just 4 screws and paying attention to what and where you disconnect from the mother board

I had a power outage & now my pc won't turn on.


It is possible that either the power supply or the motherboard is faulty.
Try swapping out the power supply (borrow one if you can) and if the PC power LED does not light up or the PC boot up, then you need a new PC.
I suggest you get a surge protection power board and connect your new computer to this surge protection power board. It will protect your computer from power surge problems.

Hello,

Depending on what caused the power outage, you may need to replace the power supply in the server. When outage happen and the power is restore. a power surge can destroy power supplies, especially if not connected to an UPS unit.

Computer will not turn on. Possible power surge.


If the power supply is good then your motherboard must have gone bad during a surge.

We had a power outage and the next day all I could get on my TV was the blinking power light. Can you hellp me? I have a Samsung 42" LCD Flat Panel HDTV Model No. LN T4042N edit


Hi, the power surge has destroyed the power supply board that is located inside your lcd cabinet. this board works in conjunction with an inverter board that regulates the raw ac current that is used for many different functions in your set. Normally, this type of damage will be isolated within the power supply but, it could have spread to the main control board as well, depending on how well the surge protector preformed during the surge.

The good news is that, this is a repairable situation. you can replace the power supply circuit board and inverter board as well. these replacements will fix this issue.

please rate and god bless:)

Opener on wall will not work after power outage


Actually it sounds like the vacation lock has been enabled. To turn it off press and hold the lock button for 2 seconds and test it out. If this is not it then you will need to replace the logic board and get a surge protector as well. Thanks BB

Power outage due to power surge, possible fuse problem, tv will no longer turn on


You have a power supply issue on the main board of your set. This is not an easy fix for a home owner, Your best bet is to call a service shop and get a price quote. Tearing into tv's is very dangerous! High voltage is present even when unplugged! Good luck!

Power outage then wont turn on


contact the power company to see what they will do for you they are responsible for power damage also the surge protection should have replacement warranty. may just be blow caps but take to a service center to have it looked at better yet have a service person come to your home to look into it.
