What is the problem?

Try selling it on EBay.

It is asking for the recovery discs that should have been made in the event there was a problem with the recovery sector on drive D or the hard drive failed. The only option is go to www.hp.com contact customer support and the technical department to see if they can sell you the much needed discs.

i dont claim to be any expert, in fact far from it. our hp paillion came with a restore disc that restores all programs/software that were origionally in the comp and also the extra optional stuff u could download at setup maybe u can get a copy of one from somewhere when ours crashed it was the only thing that got us up n running again

Welcome to Fixya
Try this test first. Press the power button then see if the Fan will spin at the back of the computer. This will tell use if the power supply is working. If the Fan spins then there is no problem with the power supply. The problem is the motherboard already.

Are there any fans moving in the case? As in, are you getting any power? If no fans are moving, it's possible it's:
1) the power supply (PSU)
2) your 'jumper' from the power button to the motherboard has come unplugged
3) you're grounding out somewhere

One cheap-o way of testing a power supply is:

Turn your power supply off.
Unplug your power supply.
Get a paper clip.
Bend it into a U-shape with the ends close together.
Put one end of the paper clip into *the* green wire in the plug of the PSU.
Put the other end of the paper clip into a black wire of the PSU.
Plug in the PSU.
Turn on the PSU.
If the fan runs in the PSU, it's safe to say this PSU is in working order.

If the the power supply was fine, but when you hit the power button and it no fans inside the case move, check the plug from the case to ther "power on" jumper on the motherboard. if that's correct, I'd suggest removing the entire motherboard from the case and setting it onto a phonebook and see if it'll turn on there.


If fans are moving when you hit the power button, but no beeps, fans turn back off after a moment, ect:
1) Motheboard is bad
or
2) Processor is bad

These are the situations that are most likely.

Computers are picky about being played around in. You can look at them wrong and they'll stop working. Sometimes it's as simple as pulling them apart and putting back together again to make them work... at least in my experience. I wish you the best of luck.

Hello,

I have to assume you are currently using the larger size called a tube type monitor and would like to have an LCD or flat screen type monitor connected to your computer.

To connect to new LCD flat screen monitor to your computer would be exactly the same connection as what you are currently using.

The only problem you could run into is the connector itself. Some of the flat screen LCD monitors do not have the older style connector called VGA, usually blue called DB15, because it has 15 pin connector. They may have only have the newer style called a DVI type. Some do have both types.

Please be sure the LCD you want has the older style DB15 connector to connect to the rear blue VGA input of your compter.

Good Luck

Hardware failure - the voltage to the processor is unstable because either the PSU or the rectifiers on the motherboard have aged. Open the case and look at the motherboard - if some of the capacitors on it are bloated then you will have either to replace them or the entire board. If the capacitors are fine in there then the fault is in the PSU - you can get a new one for less than $20 at every pc shop.

Sounds like a hardware issue. I would contact HP for service.

could be your start up driver laking to come up change your boot format to f12 then when asked rerun windows.

make sure that you have both the power connector (red, yellow and black wires with a white cap) and the drive ribbon (grey with a black cap) attached completely. go into the bios and make sure it sees it. if once you log in and the dvd operates and it doesn't see a dvd, then that usually means tht the drive is bad

Regarding the blinking green light on power supply for hp a430n...I've had that happen as well when the computer is turned off for an extended period of time. It would not immediatly power up when plugged in to power. Hitting it and beating on the button didn't help either.

However, after calming down, I noticed that when I unplugged the computer that the light continues to blink, but gradually fades and goes out. So, I thought that since power supply holds a charge after being disconnected as can other components inside a computer that I would assume the converse: It needs to power up to "full charge" as well. In my case, I was right.

All I did was plug the computer in and leave it alone for about 20 to 30 minutes, go sit and cuss for a while. When I came back and checked it after that time, the front panel blue light was on and the green light on the power supply was glowing steady. The computer started right up! Thank goodness...stopped cussing.

If it hadn't, and I had tried all the resets listed above, I would have bought a new power supply too...but not this time!
