Do I need to replace video graphic card or power supply unit on hp compaq presario sr2180nx

hello all
i saw a similar post over 4 years ago, however it doesn't address my issue.
my pc started stalling when i attempt to turn it on. It wouldn't come on. Then after several tries every now and then it would come on. I was told through searching that it could be the video graphic card or the power supply. Therefore once i had the computer back on. I never shut it off. However, i could reboot and it would come on.
Now it won't come on again. So i don't know what to replace. The video graphic card or the power supply. If it is the graphic card, do i replace the one previously installed or add a new one. And if adding a new one, what is recommended to be compatible with my 300 watt supply unit? I'm lost as what route to take and how.Below are the details of my unit.
HP/Compaq Presario SR2180NX desktop PC with a P5LP-LE motherboard with an Integrated graphics using Intel GMA 950.
*Integrated video is not available if a graphics card is installed.
Also supports PCI Express x16 graphics cards
300 watt supply.
thank you in advance for any help you can give me.

Is there an add-in video card in the slot? If so, remove it and try to turn on. If the problem is the video card it will turn on. If not it is the power supply.

Compaq CQ56-115DX Recalled Power Supply & Dead Motherboard

Hello,
We currently have a Compaq CQ56-115DX in our shop that we are diagnosing. Currently the computer turns on and sits at a black screen while the caps lock light blinks repeatedly. Upon further research we have found that it may have an issue with the bios. We are unable to get anywhere past that black screen so we cannot update the bios. We have tried pulling the CMOS battery and letting it sit for a bit in hopes that it might reset the bios. Unfortunately that didn't work. We believe the motherboard is bad. Looking at the support page for more resources I saw that there was a recall on the power supply for this machine. I went through the confirmation pages and the adapter is one of the affected models. Is there a possibility that the power supply could have caused the motherboard issue?
Thanks,
ST

It is actually a recall on the cord from the power supply brick to the wall plug, not the brick itself. If that goes bad you just get no power at all so the power supply is not the likely culprit. Is there any evidence of melting or arcing on the power supply at the place where the wall cord plugs into the brick? Does it put out power to specs? I would agree with your motherboard diagnosis, by the way.

HP Compaq 8000 Elite power supply upgarde

I have a 2010 HP Compaq 8000 Elite and need to upgrade the power supply in order to run my new Radeon HD 6850 Graphics card. After much research i found that this particular computer's motherboard does not have a normal 20-pin or 24-pin power supply but instead uses 2 separate 4-pin connections for the PWR and PWRCPU supplies and a third cable which i believe to be an ancient and outdated 6 pin auxiliary power cable (http://www.playtool.com/pages/psuconnectors/connectors.html#aux) for the PWRCMD supply. I Also found that all power is run through the motherboard to each separate piece of hardware in the computer and therefor most likely has a limit for the max power supply possible. Is there some sort of power supply that will both fit in the PSU slot (which is not the standard PSU size, but instead measures about 6" x 5.75" x 3.75") and will also be able to connect to and supply enough power to the mother board?!? Or am i stuck with a lousy 320W??? Please Help!!!

Maverickv2,
You will not be able to upgrade that PSU, model # 508154-001. It is not possible with those connectors. The most absurd item was that the hardware (drives) actually are powered off the motherboard. (Just like you said).

New power supply and graphic card for Compaq CQ3232L

Hi all,
I am using Compaq CQ3232L and would like to upgrade the graphic card with one of the HD 5770, Sapphire HD 5770 Vapor-X 1Gb 128Bit DDR5 to be exact.
My current power supply (Bestec Model ATX01...) specs are:
+12V/11A, peak 13A
+5V/10A, +3.3V/10A,
-12V/0.3A, 180W according the manual.
I've been looking a replacement for the power supply but not sure which one will fit the case? And how much power will be need to run the Sapphire card and future upgrade (Blu-Ray drive and another HDD)?
Regards,
Eko

WSH, besides measuring the PSU, you should assure that there is sufficient space for the video card. Open the case. Measure from the edge of the case to the opposite side of the motherboard where the PCIE slot is located. This is the approximate length of the card that will fit.
Also, I like OCZ and Corsair PSU's. They are both enthusiast/gamer manufacturers. Their products will provide clean, stable power for your system.

Compaq Presario Cq1-2025. Do These Have A Power Supply?

Have one of these that just stopped powering on. I get a little green light in the back, but no sounds or beeps or images. On a regular desktop computer I'd just replace the power supply and I'd be good to go, but I don't think these have a separate PS, and are more like an overgrown laptop, with a chunk of the mobo dedicated to providing the power.
Is this a candidate for the local recycling bin?

Hi,
It IS the power supply. As in my first reply, it uses a similar PSU with a laptop.

Help! power supply

i bought a compaq CQ5110Y and wanted to get a ati radeonHD 4650 1gb ddr2 pci E video card but this video card
needs 400W. I have a LC-B450 E power supply from my other pc and i was wondering if i could replace it with this one.

Hi, Rennwerkes.

and here:
http://jimwarholic.com/2008/11/apple-imac-g5-power-supply-issues-and.php.
I think i saw new PSUs in the US offered for about $140. Here in Europe they are twice as expensive...
however, temperature problems might indicate a different source for the problems. Are the venting channels clean and the fans running? The G5 processor is quite hot - since short i have an Intel, and it's much less heating up! - especially if you have graphics or many windows open. (It depends also n which model you have)
There are also DVM's (Digital Voltmeters) with which one can measure a capacitor, but my attempt to do this with the capacitors on the PSU was not successful, probably due to the residual capacity of the surround print parts.
If you have access to a decent fast oscilloscope, you can check the PS voltages. If they are stable and without spikes, then the PSU is fine. If they are spikey, then a new capacitor can help.
Hope this helps

Power supply reuse

Hi,
I'm trying to give my good old Compaq Presario Windows 95 computer a new life. That is to use the cabinet and the power supply (+12V, +5V, both very interesting) for a project for which I was to buy a power supply anyway.
So I was thinking, let's give this old beast a new life. Af least it saved the environment of another part of electronic waste.
By the way, the power supply is a MITAC SPU-75.
I am aware that the reuse of PC power supplies usually requires a few rules to follow. There should be some load on the +5v and one of the connecting wires needs to be put to ground to convince the power supply it is supposed to be "on".
That's what I thought until I tried it with this little beast. Being an old Compag the connectors are non standard, 2x 6 pin.
Does anyone have experience in reusing this type of power supply?
Regards,
Reinhold

Picolit Power Supply Unit

I have the following PSU in my Envy 750xt: IPS,ATX,Picolit,500W,EStarBronze,5Vsb/4A - 746177-002
My question is will this PSU work with an uninterruptable power supply that outputs a stepped sine wave (only when on battery power)? I am also curious if this PSU uses Active PFC.
Thank you.

The P/S requirements are overstated.
The card draws a max of 29 Watts and is a favorite to install in the HP business desktops with the 240 W P/S.
It is also the optional graphics card on the HP Elite 8200 SFF with the 240 W P/S.

I too have had power supply problems with my HP G60-445 DX Notebook. For the past several months I have needed to jiggle the power cord to get the battery to charge. I finally took it to a computer repair shop. He ordered an internal power supply box and installed it and after a bill of $125.00 for parts and labor found out that it did not solve the problem. Dan, the repair person called HP support to ask if they knew of similar problems and if so what is the problem. Support told him "they don't know of any problems with the power supply" What a lie! The problems are all all over the internet!!! Support told him that if they had to "guess" they would suggest replacing the motherboard. Dan proceeded to let support know that they absolutely know there are problems with their product and they are choosing to do nothing about it. You can tell they have made a piss poor product for years and continue to do so without regard for the consumer! Dan, in his repair shop, has more repairs form HP products and with Compaq products than any other computer! I wish I knew this before I bought this laptop!
So, now I have the laptop back with a new power supply module and still have an issue with the battery not always charging when plugged in. I will not pay $300 for a new board and will probably buy a Dell when I have to replace this one. Please spread the word that HP does not listen to consumers nor care enough to improve their products after years of the same issues.

JCGood1984, welcome to the forum.
The computer should take a standard ATX power supply unit (PSU). I suggest measuring the existing PSU and compare the measurements to the one in the links. If the measurements are the same, it should fit. I don't know anything about the brand, however.
