I just got a new HP computer with Windows 7 pro. When I install the graphics card, Nvida Geforce GT 620, the pc will not start. It appears that the pc freezes before loading Windows 7. The monitor stays black and does not show anything. When I remove the video card and restart Windows I get an error message saying that Windows did not start correctly. How do I correct this? I can not do anything in Windows 7 because the video card is not there for Windows to see. This video card worked fine running Windows XP 64 bit on the old pc.
 
Solution
OK since this is a pre-built HP did you check to make sure the system has a adequate PSU for the GPU you are using. I know the GTX 620 is on the low side but most of these system come with a PSU just big enough to handle the power requirements with the parts they are shipped with and no more.

OK barring the PSU boot Windows 7 up in safe mode, press the F8 key before the Windows 7 logo comes up. You may have to hit the F8 key several times to get it correct keep trying if need be. Then go in to the control panel and remove any Nvidia graphics drivers that may be there. After that try to boot back into Windows the correct way. If you get to boot up completely download the latest drivers for you GPU and install. After one more reboot...

First, thank you for replying.
1 - It does not matter if the monitor is attached to either the video card or pc - I have tried it both ways when starting Windows 7.
2 - I am very new to Windows 7 and do not see how to get into the BIOS. BIOS setup does not show at the booting up of Windows 7 as it did in Windows XP - How do I get to the BIOS? And what adjustments do I need to make? I would like to get away from VGA and go with DVI as my new monitor will do both.

I do not know. This is a brand new HP desktop and was just put together this past month according to the paper work. So I would assume that it is the newest BIOS.
 
Go to hp support page for your pc. Under download download the newest bios and run the program if the bios is at the same rev hit exit if not let the bios updater run and reboot. If it not a bios issue then it coud be an under sized power supply what the model of the hp and the size of the power supply.

I am not sure on low end cards but does the GTX 620 need PCI-E power cable? Or is it bus powered?
 
Solution
BIOS:
You need to press either the F2 or DEL key after you turn on the computer. Obviously you need your monitor attached as it was originally. If you see no indications of when to press it, try F2 then the DEL key both one after another. You should then boot into your BIOS.

BIOS SETUP:
Once into the BIOS, you need to find the section related to graphics. There should be a setting which gives options like:
a) PCIe->iGPU
b) iGPU->PCIe
c) AUTO (PCIe if available).

Go ahead and choose the option that has PCIe as the first choice (though Auto may work). Then, SHUT DOWN your PC, attach the video card, then attach your monitor to the DVI output.

DIDN'T WORK?
Odds are your PSU is adequate. Odds are also that the graphics card is fine. Other than borrowing a different graphics card (any card with no power connectors) to test if your card is defective I don't know what to tell you.

If a friend will let you borrow his PC to test your graphis card you can also verify the card that way.
