It might say 750W but whether it can reliably provide it is a whole other matter. The original Dell version of that has a good review (http://hardwareinsights.com/wp/dell-h750p-00-review/), but a good 750W supply would be expecting to handle one or two high power GPUs and yet yours only has a single six-pin PCI-E connector, not even a 6+2.

From what I can find quickly, a GTX580 requires northward of 35-40 A on the 12V rail. Your PSU struggles to provide this even if you combined two rails. And if your GPU has two 8-pins instead of the usual GTX580 8+6, it likely needs towards the higher end of that current.

I would strongly suggest getting a new PSU. Use http://www.tomshardware.co.uk/forum/id-1804779/power-supply-unit-tier-list.html...

The red light usually means OC mode on the gtx 580.

1. Can your PSU handle that card? Is the card plugged into the PSU?

2. Make sure the card is in the right slot.

3. If the card is in the right slot, make sure it's properly inserted. You should hear a click indicating it is in the slot securely. There should also be a screw that you screw into the top metal flap hovering over the slot on the side of the case.

4. Connect the cables from your PSU to your card.

Has the computer turned on at all since you've installed the graphics card? If so, did you see anything on your monitor? Were fans spinning?

Have you heard any beeping from your machine?

Yeah 750w should handle it.

I'm not familiar with the GPU, I'll look it up when I get home I'm on my mobile. Most modern GPUs require a cable from the PSU.

What happens when you turn the computer on? Does anything beep? Do all the fans and everything work properly including your CPU fan?
If your card has fans, are those spinning?

No fans spin at all or just the fans on the gpu?
what lid? The computer case lid or something on the cpu itself?

Uninstall (take out) your graphics card and try using your onboard graphics tot install the drivers for your graphics card and then reinstall it.

Yes, it will be that.

The majority of cards these days require more power than the PCI-E slot can provide, so they include extra connectors for connection to the PSU. If the supplementary power isn't provided everything may turn on but the graphics card won't run. I had an old AGP card that would output an explanation to the screen if the 4-pin molex wasn't connected, but I guess yours isn't so helpful.

The big questions are whether your Dell 750W has (a) the right connectors or (b) can supply enough current on the 12V line if using adapters. Two 8-pin connectors means some hefty requirements, so you might find you'll need to replace your PSU.

So does your PSU have two 8-pin connectors that match the sockets on the card, or if not what can you read on it re its make, current details etc?
