Hi all, I've just put a graphics card into my pc and now I'm not getting any display, boot even the boot screen.

The card is a GeForce Gtx 260 oc

My motherboard is a foxconn 945g7ma-8ks2

The psu is an atx power atx 500 td

I'm having to use 2 Molex to pci-e adapters for the 2 6 pin pic-e connectors as well
 
Solution
I’m hesitant that you’re running the GPU using two Molex to PCIe adapters, as this tells me your PSU was never intended to run a modern graphics card. (even if a GTX 260's 6 years old, its more modern than that PSU) i highly recommend buying a new computer, or at least getting a modern PSU. A cheap Pentium Anniversary processor will run circles around what you can run in that Pentium D ready board.

But, for some possible solutions...
1: Check if the motherboard is outputting video over its integrated graphics solution. if so, motherboards normally have a setting in their BIOS that allow you to manually select the video adapter.
2: Reset the CMOS battery. Remove it and count to 30, after that reinsert it. I’ve had some GPU's not behave...

what brand PSU you got?

500w is barely enough. (card needs 36 amps)

the card needs 2x +12v rail connections, make sure you have that

if your psu only has 1 +12volt rail, delivering anything less than 36, you need a better psu

2: Reset the CMOS battery. Remove it and count to 30, after that reinsert it. I’ve had some GPU's not behave properly till I cleared that before.
3: Try the card in another working computer. It’s possible the card died between whatever was its last computer and your current one.

Thanks gents for your replies, I have just picked up a corsair cx600 to try out when I get home and ordered a xfx 750i with a quad core processor so hopefully one way or another I'll be up and running again but I'm grateful for the sensible and straightforward answers. This I'd clearly a great forum to be a part of
