Problem installing a GTX 770 into a Lenovo k410 (Lenovo Mahony Mobo)

[Lipsofdeceit]

I recently purchased a Palit Geforce Gtx 770 to upgrade my system, I also bought a Ocz 750 watt Psu to support the new card.
When i install the card into my desktop and switch the computer on, i get the Lenovo logo startup, followed by 3 loud beeps from my desktop spaced about 20 seconds apart, after the 3rd beep the screen goes blank with a flashing underscore in the upper-left corner.
I have uninstalled and reinstalled the card many time but with no luck, i have also searched all day to try and find if people have compatibility issues with the Gtx card but no luck with that either. I am running on windows 7 so it cant be the secure boot problem.

If anyone has any ideas or have had the same issue please do share, im thinking about getting a refund on the card even though i think there may be an easy fix.

System specs.
Lenovo k410 Idea centre
Chipset: Sandy bridge
Bios version: ECKT18A
Graphic interface: Pci-Express
Processor: Intel i5 2320@3.00 ghz
RAM: 8gb
Current grapics card(Ready installed): Radeon HD 7570

And i believe the MOBO is a Lenovo Mahony but no more information on that.

Ps: I have installed my original graphics card back in even with the new power supply and the computer works as usual, Just not with my new card 🙁

Did you connect the two PCI-E power connectors to the new card?

Yes i did, a 6 pin and an 8 pin, the card would light up and the fans would work, but like i said, no boot-up just the 3 beeps and blank screen

I am having this exact problem.
Lenovo K410
Windows 7
Intel i5
Same everything, except I am trying to install a Seasonic 650W psu and an Evga Gtx 760.
Same problem, posts to Lenovo logo, sits on that, 3 beeps 20 seconds apart, then goes to black screen with flashing underscore in top left.
It turns off immediately when I press the power button, no holding.

Sorry I don't have any answers, but I heard misery loves company.. :0
