We have a compaq persario. We just had it on a few minutes ago, but we unplugged it to move it just right down the hall from the living room to the bedroom. My husband went to set it back up and turned it on. But it wont power up, everything we plug it in we get a clean light that just blinks, when he unplugs it the light stays blinking. We were wondering if its the power supply but wanted to make sure before we spent the money.

If it is a Desktop it could be anything and if it is a NB which sounds more likely because you say

[i]everything we plug it in we get a clean light that just blinks, when he unplugs it the light stays blinking[/i]

If it wasn't a NB the light couldn't stay blinking when the Power is removed.

So how did you turn it off.

Sounds much more likely that it wasn't turned off but in Power Saving/Hibernation Mode to me but I could be wrong.

What is the Model Number of this Persario? After you post back with that we may be able to help you here.

that is what is confusing us it is a desk top, he plugged it in and the green power light came on and just blinked when he unplugs it, there is a greenlight on the back that keeps blinking but the one on the front stops.

Best guess here is that it's either not correctly connected or that something came loose when it was moved.

Start off with disconnection everything again and this time only plug in the Monitor, Keyboard, Mouse and Mains. Then try booting again and see what happens.

If it doesn't boot now remove the side cover and check the connection of all the internal cables something may have come loose and this is the problem. When you are inside the case make sure to have one hand on the metal of the case and don't move your feet around to generate Static Electricity. It will kill Electronic Components faster than you could believe possible.

Or in a worst case scenario some external powered device has failed and is putting mains voltage into the case where it is plugged in. I saw a set of speakers trash half a network once when they failed and did that. But they saved the owner massive amounts of money as the new ones that I wanted to sell him cost $20.00. :D

For the LED on the back of the unit there has to be power from somewhere getting in so if you can reduce the system to as little as possible this will point to any faulty parts connected to this computer.

that you need a new Power supply.

I had the same problem, when I replaced my old HP, I was going to use it as a backup server, but after unplugging it (and moving it about 1 meter) it would no longer turn on. solution was to get a new PSU

The green LED on rear of power supply should be steadily lit when PC is plugged into an outlet (has power). The LED has a decay time of 15 seconds or more when power is removed, so it should go out after a short while.

The flashing LED on the back of the case may be one of the LED's on a LAN Connection. That is about the only thing that may remain on when the unit is unplugged and not be a problem.

If it's not that I don't have a clue what it is.

Realise that the move isn't possible because the cable is still connected to the AC Mains outlet.

They then remove all cables and move a computer that truly IS shut down.

The initial attempt, when the computer was still live, had trashed the hard drive.

Not often, but it has happened. ;)

An AGP video card can come loose just by moving the computer 3 feet from one desk to another.

The AGP slot is very tempermental.

Some manufactures used to add a tie strap to the back of the card to keep it in place. Many new machines now incorporate a retianing clip that snap over the connector on the motherboard and has a part at the back of the slot that hooks into a small slot in the lower back corner of the card.

Unplug the A.C. from the computer.

Remove the side cover.

Carefully but firmly press the AGP video into the slot. It is usally the card closest to the processor. The slot is a little further from the back edge of the motherboard than the pci slots as well.

If this does not correct the problem you may have to remove and re-seat the AGP vdeo card.
