New Graphics Card not working

[tmavvy]

I have an HP Pavilion HPE H8-1120 desktop computer. (http://h10025.www1.hp.com/ewfrf/wc/document?docname=c03019166&cc=us&dlc=en&lc=en#N589) These are all the specifics about the PC. The graphics card I'm trying to install is (http://www.evga.com/Products/Product.aspx?pn=01G-P4-2751-KR).

So here's my problem. I want to upgrade the graphics card so I can play games on higher settings. It currently uses a GeForce GT 530 perfectly fine, but when I put the GeForce GTX 750 in, the computer turns on but stops booting up at the blue HP intro screen and the card beeps. I figured it's probably the terrible 300W PSU but I switched it with an EVGA 500W PSU with high amperage on the 12V line for the card. As far as I can tell the card doesn't have any 6 or 8 pin connectors for the PCI-E so I just have to put the new card in the slot. I've updated my BIOS from the HP website and it still hasn't worked. I'm thoroughly confused and need some help from an expert.

Any advice would be very much appreciated.

The most likely culprits is either a bad card, improper seating of the card into the PCI-E slot, or the motherboard is not able to supply the required 60W of power through the PCI-E slot. Try the following:

1) Install the old video card to verify the PCI-E slot still works
2) Reinstall the GTX750 and verify proper connection to the PCI-E slot
3) Test the card in another computer to verify if it's a defective card

That was one of my original thoughts Ninjawithagun, I've taken the card out and the put the old one in 2-3 times thinking I missed something and the old card always works, the new one doesn't. I don't think the card is bad though because the fan on the card turns on and this is the second gtx 750 i bought. I returned the last one because I thought it was DOA for these same reasons but I think it must be something else.

The GT530 requires 50 Watts to operate, whereas the GTX750 requires 60 Watts. The only thing that makes sense is that the PCI-E slot is not providing enough power to the card. There is absolutely nothing that can be done for this other than buying a newer motherboard that can support 60 Watts through the PCI-E slot.

Here are some suggestions that you can try:

For step 1 you will need to access the BIOS. The directions to do so are here:

http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&dlc=en&docname=c03102341#N1355

1) In the BIOS, go to the Advanced Menu, then Bus Options, and disable PCI SERR# Generation and reboot. If that doesn't work, try enabling PCI VGA Palette Snooping

2) Verify that you have the four pin power cable connected to the motherboard (to the lower left of the CPU)

3) Verify that you have unplugged any cable connection to the motherboard video output ports associated with the integrated graphics

I do hope one of these steps helps resolve your problems installing the GTX750.
