New graphics card isn't detected

[BlackShuck]

My PC:
Asus mother board: P87ZZ-V LX
CPU: Intel i5
x2 western digital 1tb hard drives
x6 corsair high performance fans
x2 4gb RAM
x1 disk drive
PSU: CX600M - 600watt

Old GPU ASUS geForce GTX 650
new one is MSI Geforce GTX 770

My new GPU is not detected by my PC. It won't even show the Bios.

Tried:
-reseting Bios
- re-seating GPU
- it is defiantly plugged in to GPU, and onboard does work
- updated all of my drivers for my mother board


another issue:
in the bios I set the the graphics to PCIe, then I save and restart. I get no video and when I go back into the bios and its set back to auto. The CMOS battery is working as my time and date aren't being reset every restet

- GPU isnt shown in device manger

Really frustrated with this. I have searched many of these types of threads and to no luck have I had it working.

To add, it did work on its first run then I installed the drivers (proper drivers) and ever since windows ignores it.

Thanks

How can I tell if it has enough power going to it.

Oh, and both 8pins are connected firmly as well as the PCIe.

Try uninstalling all the drivers from the old GPU, reinstalling current drivers, and try the card in a different slot. If it still doesn't work I don't know what it could be, maybe a faulty card.

The CX series of power supplies are known to be problematic. The minimum system requirements for a GTX 770 is "600 watt or greater power supply with a minimum of 42 amps on the +12 volt rail". It is quite possible that you are not getting sufficient power. You can try a 650 watt power supply (Seasonic or XFX OR EVGA)

On the other hand it may be a bad graphics card. Does it show up in the device manager under display adapter? Under properties it will show any drivers installed as well.
