My hp Compaq DC7900 has 5 beeps with 5 red light flashing does this 3 times. then the fan kicks on. That's all it does. Anyone know what this is?


This is a sign of a pre-video memory error. If your DC7900 has a video graphics card, that card has probably failed or doesn't have enough power. On at least some of HP's Compaq DC7900, the video card uses a PCIe x16 slot.

There are two things to consider when you choose a new video graphics card: 1) it must fit in a slot in your case and 2) your power supply must meet the requirements of the card. The small tower format of the HP Compaq DC7900 came with a 240W power supply. Most modern video graphics cards often need more power. You may need to upgrade the power supply.

I hope this helps.

My HP D530C does not power on. The power LED flashes 4 times. What is the fault? Pls let me know asap. Thanks.


HP xw6200 Workstation - Diagnostic LED Code: Four Flashes ISSUE: When the workstation is powered on, the front LED might flash red four times, once per second, followed by a two second pause. SOLUTION: The front LED flashing four times is a sign of a power failure. To fix this issue, complete the following steps:
  1. Open the access panel, and check to see if the four-wire power supply cable is properly connected to the system board.
  2. There may be a faulty device. Locate it by removing all devices and then reinstalling them one at a time until the workstation fails. Replace the device causing the failure. Continue adding devices to ensure all are functioning properly.
  3. Verify the power supply functionality, as follows:
    1. Disconnect AC power.
    2. Remove all internal power supply cables from the system board.
    3. Plug in AC power.
      • If the power supply fan spins, and the BIST LED illuminates, then the power supply is good. Replace the system board.
      • If the power supply fan does not spin, or the BIST LED does not illuminate, replace the power supply.

Green light in rear flashing won't part up


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)

Install new power supply?


The monitor is not receiving any signal from the PC. When you push the power button ON, is there any activity on the PC (LEDs on, power supply fan, etc) or it's just dead ? In this case, yes, the first thing to check is the power supply.
