I recently opened up my CPU in order to clean out the dust, I do this at once every three months. This time unfortunately, after cleaning I plugged in the AC cord and the LED light starts flashing and the computer will not come on. There is no power, I can't even boot up. I had someone look at it and they tell me that it could have been a power surge after I plugged the CPU back in or I may have accidentally unplugged something internally during cleaning the dust out. I assure you, I didn't touch anything that would account for anything coming unplugged internally ( I sure hope not). They also told me that the motherboard and hard drives could've been damaged. Is there anyway I can fix this? Is it a possibility that my hard drive, files and other programs are saveable?
Computer won't turn on

Nine times out of ten when your press the power button and it does nothing you will have to get a new power supply.

Is your system a pre-built such as a Dell or HP?
Look at the side of power supply. There should be a label showing max wattage and apperage of each voltage. If you don't run a graphics card then you will only need the max wattage.

I plugged in the AC cord and the LED light starts flashing
Is this the LED on the mother board?
Do you hear the fans on the power supply turning/ running?
The symptoms due point to the psu, and 300 watts is not much in this day and age.
As suggested, put your HD in a friends to get the data, just to be safe. Do you have another psu you can borrow? from a friend?

The flashing led below the AC line in connector is indicative of a failed PSU. HP and Sony both used power supplies with this feature in some models. Replacing the power supply should get you back up and running. When you replace it, give yourself at least another 100 watts...as was mentioned earlier, 300 watts is not much power these days.

I would replace one thing at a time so you don't end up replacing something you really don't have to. I still recommend backing up your files to a friends computer before trying to fix the machine. One thing that you can specifically check on your computer now is the CPU fan. Make sure the heatsink is secure.

Don't laugh, what and where is the heatsink located. The fan seams to be secure but it doesn't come on. Thanks for the link to the power supply but I already ordered the same model # power supply because I wasn't sure if I could put any other kind in. At this time I don't have another computer to hook up to other than a laptop.
Thanks for the other comments also, I'm new at understanding the inside of the computer so forgive my ignorance. The power supply that I ordered should arrive by Tuesday. Will this be easy to install? How will i know if the problem is beyond the power supply?

Are you talking about the fan in the same area as the blinking LED?The fan seams to be secure but it doesn't come on
The power supply will be pretty easy...just four screws in the rear and some cables to switch. Just be attentive and it should go quite quickly. I'm fairly confident that this will get you running again.

My CPU has three fans. One for the Power Supply, One sits on some silver thing on top of the motherboard and one in the back of the CPU. they all seem to be secure but they don't come on when I plug in the power cord. When the power supply I ordered arrives, we shall see. I do know that before this problem happened the LED light for the power supply would be steady and when I hit the power on/off button on the front of the CPU the computer would boot up.

My replacement Power Supply arrived yesterday. I won't be able to install it until This afternoon or Saturday night. Is there anything I should know or look out for?
