Does not power up. was on a surge protector. lost power in building several times during hurricane Irene


A surge protector is there to protect against high spikes in electricity and not fluctuations.

The possibility exists that the components were damaged due to fluctuations in the electricity received by your computer. It is for this reason that an UPS or Uninterruptible Power Supply would most likely have saved your computer as it helps provide your computer with a smooth supply of electricity.

One would assume that the power supply is somewhat toast however in most cases it is unfortunately the most fragile component that goes first, being the mainboard. See my published guide to help and diagnose the faulty components, entitled
My Computer is not turning on!!! Is it dead!!! No POST!!!

Make sure that the wall outlet is working, test it by pluging a device into the outlet, check that it is being powered. Also in some computer power plugs a Fuse is placed within the actual plug. If this is the case then you may be in luck as it would then be possible that the fuse is blown. One would then replace the fuse and presto good as new.

Let me know how it goes!

Take care!

PC would not power on? My PC wouldn't power on today, I checked all plugs on surge protector inc the fuses all seemed ok. I took all plugs out turned power off at socket for five minutes and put all plugs...


The tower has a self contained power supply module that is the problem, it must be replaced for a new one, you need to bring the tower to a computer repair store for service, because they have to install the correct power supply for your model.

My tower wont turn on


Obvious places to start is checking that the power cable is in all the way, switched on at the wall socket and that the fuse hasn't blown in the plug/extension lead. If they're all ok it could be a dirty contact or a faulty switch on the power button, a loose connection attached to the switch or worst case scenario your main PSU (power supply unit) has died. It's not the end of the world if it has, swap out the old one and invest in a quieter replacement from QuietPC

The computer seems to get no power.


unplug the power cord from the power supply on the computer, wait 2 min. plug back in and hit the power button...if the computer does not turn on, then the power supply has a short in it or a bad fuse.....you would have to either replace the power supply or the fuse inside the power supply...i would just get a new power supply....

I moved our computyer from downstairs to upstairs.


Power supply is bad,,

You can try to unplug the main motherboard plug, then plug back in,, It should last as long as it stays pluged into the wall.

Keep it pluged in when you do this,,

On pluging on the main AC pluf, there is not


do you have the cord plugged into the computer? is there a switch on the back near the power supply? if so, is it on? is the large connector from the power supply tightly latched to the mother board? (unplug the computer before you check this!) any fans running? plug a lamp into the outlet and see if it has power! could be a popped breaker, or blown fuse.if you feel confident of your skill, remove the power supply, open it up and see if it has a fuse that may be blown. if so, replace it with a fuse of the same type (size & amperage). if the fuse was blown, and you re-install the power supply and it blows again, then you have a problem (probably) with the power supply, and if cost effective, it needs replacing! get a compatible power supply with a higher power rating, if you can! more power for your peripherals!
good luck!

Will not power on


Not much to go on .... however ...

Check the mains
Check the mains plug
Check the mains plug fuse

If this is all ok, then it is likely to be a faulty power supply. These can be bought for around 40-60 GBP and are reasonably easy to fit.
