I need some help form you

makes sure dust free from your power supply. but does sound like you going to have to buy a new power supply., not really any way to test power supply, you may only have enough power to spin the fun on the cpu, turn on some light but not enough to start up the computer system or even boot up. amazon.com you buy one 18.00 to 25.00 look for deals of the day where shipping free. have in a few days

You would need to look at the BIOS manufacturers site for the beep code and it's meaning. You can also pull all the hardware out, memory HDD, CD/DVD and boot if you no longer get the error, power down and add one component back and boot. Repeat until you get the beep code again and you will know what the problem part is.

Yes, it means a bad Power Supply.

Try cleaning out the inside of the computer first. Use a can or two of compressed air for computers.

The exact Product Number (P/N) is on a white Service Tag. On the back of the computer, or on the side. Usually next to the Windows product key.

The computer could not read your copy of Windows from your disk-drive.

Either:
* there is no electrical power getting to the disk-drive (check the power cable)
* the "data" cable between the motherboard and the disk-drive is faulty or not-connected (check it)
* the power-supply in your computer is not supplying power to the disk-drive (try different power-supply)
* the disk-drive itself has "failed" (maybe, the motor that spins the disk-drive has failed)

Take your computer to a professional technician for trouble-shooting.

Replace the Power supply unit and tell us wut happen...................

The green light flashing is a diagnostic LED light, telling you there is a power failure.
More specifically a bad Power Supply.
Weak voltage power rail.

The Power Supply used in a Compaq Presario SR1010Z desktop computer, is a 300 Watt unit, and is an ATX form factor.

[ATX form factor for a Power Supply, denotes the size of the Power Supply case, and the shape.
It is approximately 6 inches Long, 6 inches Wide, and 3-1/2 inches Tall.
The ATX form factor for a Power Supply is used in over 90 percent of the personal computers out there, and is as readily available as the air we breathe]

Usually, HP uses one of three generic Power Supply manufacturers.
1) Bestec
2) Delta
3) HiPro

All are low quality Power Supply manufacturers.

This is HP Support, and the main menu page for the Compaq Presario SR1010Z desktop computer,

http://h10025.www1.hp.com/ewfrf/wc/product?product=1146324&lc=en&cc=us&dlc=en&submit.y=7&submit.x=6&lang=en&cc=us

If you click on Manuals, then on Upgrading and Servicing Guide on the following page, there are instructions on how to open your computer case.

This is instructions on how to replace a Power Supply, from HP Support,

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01356113&cc=us&lc=en&dlc=en&product=3548196

(It's for a Pavilion a6230n desktop computer, but after you open the computer case of your Compaq Presario SR1010Z, the instructions are the same)

What Power Supply would I recommend?
There are 100's to chose from.
This is but one example,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3276575&CatId=1078

Chosen because;

1) Maximum wattage is rated at 450 Watts.

A computer ONLY uses the power it needs, and NO more.
Wouldn't matter if you had a 10,000 Watt power supply, (No such thing. An exaggeration), if your computer only needs 100 Watts, it would only use 100 Watts.
(Surfing the internet typically uses 100 watts)

2) Has all the power cables you'll need, and more. Tie up the power cables you do not need. (Use plastic ties, Not wire, or bread wrapper ties)

3) 24 Amperes (24A) on the 12 volt power rail.

4) 135mm cooling fan.
The cooling fan on the Power Supply you have now is 80mm.

A larger fan turns slower. Produces as much air as a smaller fan, (Or more), but makes less noise.
Less wear on the fan's bearings also.

5) Is an ATX form factor Power Supply.

6) It's 80 percent efficient, compared to the 60 percent efficient Power Supply you have now.
(That is, if it was working)

It all depends how many beeps there were.
From http://h18000.www1.hp.com/products/quickspecs/12253_div/12253_div.HTML
Diagnostic LED Explanation Table Number of 1-second red LED blinks followed by 2-second pause, then repeats:
2-processor thermal protection activated
3-processor not installed
4-power supply failure
5-memory error
6-video error
7-PCA failure (ROM detected failure prior to video)
8-invalid ROM, bootblock recover mode

I have only really come across 4 beeps = order new Power Supply or 5 Beeps = reseat the memory and hope it works

Hi, my name is ArmyMason, hate to tell you this, but it sounds as if you have a bad Processor. Did you recently experience a bad storm with lightning? Was their a lot of dust on the fan? Lightning could have struck the computer and killed the processor or excessive overheating of the processor could have also been the case. If it was a lightning strike I would contact the insurance agency and have them replace your computer. Reason I think its the processor is because you don't recieve any post and the fan spins for a second and then shuts off.

One other thing you can try, open the case and disconnect the power supply from the motherboard. Let it sit for 10 minutes, hook it back up and plug in and turn it on.

Let me know how it works out.
