Installed new graphics card now system constantly reboots

Specs: Windows 7

I recently installed a new geforce GT620 graphics card in my HP p6000 desktop. I have 6 gig ram...a 550w antech ps...and am running win 7. The system works fine, but as soon as the video card is installed and the system constantly reboots. When I take the video card out the system works just like before. What coulb possibly be my problem.

Thank you in advance.

Could be a compatibility problem, perhaps it was not pushed in making solid contact with the mother board. Could be a defective card. Do you have power going to the video card card, some times people forget good video cards require a power connection from the power supply. Can you get into the bios? If you can, is the the video graphics being picked up as pci/e or on board?

I have re-seated card 3 times. I also looked in my BIOS for a PCI setting or a video adapter setting, and there is nothing. The BIOS on this computer is the most bare bones...worst crap I have seen. Also there is no additional power required for this sli or anything.

That card only draws 29W so it shouldn't need an auxillary power connection.

There are many versions of the P6000 series. Most likely problem is the graphics drivers.

Install the latest drivers for that card. Get them from the link below.

"The BIOS on this computer is the most bare bones...worst crap I have seen"

Most OEM manufacturers only offer bare-bones BIOS. Did you uninstall the onboard graphics driver before you installed the card?

"GT 620 is a GT 530 with a 49-watt TDP and twice as many CUDA cores as the 610 -- although a meager 64-bit memory bus will put a cap on any performance gains."

In other words, the GT 620 a low end/entry level card. Your PSU should have no problem handling it unless it's on it's way out? I assume you meant ANTEC? Which model?

Can you get into safe mode via the F8 boot menu?

Before it reboots does it momentarily display a blue screen?

I am thinking of disabling the onboard adapter in device manager.....however, I am scared that If that does not make geforce card work, I will be stuck with no video at all since I cant access anything video or PCIe in BIOS. What do you think?

"I am thinking of disabling the onboard adapter in device manager"

Do NOT do that! You should have uninstalled the onboard video drivers before installing the card. After the card was installed & the monitor cable connected to it, you should have booted up & immediately gone into the BIOS to change whatever setting is necessary to disable the onboard, return the shared memory to the system, change the initial display to the PCIe slot, etc. We can't see your BIOS screen but there should be some sort of option to disable the onboard.

Did you click on the HP link I provided? Step 1 = remove video drivers. And later in the explanation = If your PC was using on-board video (no video card), then disable on-board video in the BIOS to prevent possible setup problems

You also haven't provided any info about your PSU or the exact model of your system (p6000 is the series). It's unlikely the PSU is the problem but you never know. You definitely didn't need a 550W PSU for the lowly GT620/GT530 but did you upgrade them both at the same time or have you been using that PSU for a while?

I did read the link you provided. However I am stumped as to why there is nothing in the BIOS to enable or disable anything Video related....there is also nothing in BIOS relating to the PCIe slot. The model is a: HP P6210Y. It is an AMD processor. In the BIOS the only on board hardware option to mess with is the on board Audio.

Here is what a search yielded for my models BIOS.....

However...the screenshot of the BIOS in this link shows more options than are available to me. I have nothing close to all the options the screenshot shows....I am stumped.

You said it was a new card...did you ever think about calling the tech help on your problem? It should be under warranty

Looking at the menu options shown for "BIOS version 6 & less", you need to go to the Advanced menu, change the Primary Video Adapter to PCIe & change the Onboard Video Memory Size to 0MB. You should also set Plug & Play OS to No.

If none of those options are available to you, have you tried updating your BIOS to version 5.22?

And why do you keep dodging the questions about your power supply?

Are you sure you are fully inserting the card into the slot? You should get video at post even without proper drivers.

Have you tried exchanging the video card to eliminate it as a problem?
