Its a HW problem> u need to open up the side panel> Disconnect the ATX connector(that's the thickest bunch of power cable with a 20 pin white connector on the motherboard)> if the light at the back is steady the motherboard has gone bad> if its off the power supply has gone bad

    I diconnected the ATX connector and the green light stoped blinking and stayed green steady, but when I reconnected it the computer powered up and is running fine. Now i'm afraid to shut it off. I don't know if I should and I hevent tried, any other advise?
    Thanks either way, at least its up and running.

Here is the link to testing HP power supplies but the blinking light usually means that the power supply is dead.

A450N needs new monitor - what monitor specs are required?


Any monitor will do unless you are trying to get one with the built in speakers that you have. Just make sure the monitor has the same type of connection that you currently have (VGA, DVI, HDMI, etc).

My computer will not power on, only a flashing green light on the back is on. I just bought a new computer and would like to transfer my files to my new computer. Why my old computer will not power on?...


Hi and welcome cj4man1 !
Extract the Hdd out of your old computer . Place it in a external usb box and connect the box to your new pc . You will be able to access and transfer your data .
The issue about your old computer is another matter an could have several reasons , such as power supply , damaged Hdd , defective memory , damaged motherboard ...etc ...
best regards ,

My hp a450n wont turn on after we had a power outage. It was in a surge strip as was the router etc. Everything else was fine. There is a green light flashing under the power cord into the computer?


Power supply was probably nuked. You can get a replacement from ebay or usually a local computer repair shop. They go for around 20-35 for most "generic" power supplies. Unless you're a hardcore game or crazy you probably will just need an ATX power supply. Easiest thing to do is just take it down to a mom and pop computer place and have them sell you the right one.

ANYONE can replace it. It's just four screws to take it out, then just plug the cables back.

Some HP models use a proprietary power supply, if this is the case with your model then eBay is the place to get a replacement. Just match up the power supply model numbers and you're good to go.

Let me know if you have any other questions.

My hp a450n won't turn on. We had a thunder storm


Was the PC running when the storm struck? In that case changing the power supply knows as SMPS which is inside the cabinet needs to be replaced provided your monitor when independently connected to a power outlet, gives a display or says 'no video signal'...................sodeep
