Issue with new GPU

[TomClothier]

First of all thanks for taking the time to read my question,
Just purchased a new "MSI GTX 660ti Twin Frozr IV 2GB DDR5".

For some reason when I mount the card in the the PCI-e 16x Gen 2.0 slow it goes to windows "Enter the bios" screen makes 3 beeps then goes to a black screen with a white underscore. I have tried remounting it several times to see if that helps but no luck. My power supply is fine (Corsair TX650m).

My system specs are as follows:

Corsair Vengeance 8gb(4gbx2) DDR3 Ram
1TB 7200rpm HDD
Intel i5 2400 CPU
Corsair TX650m PSU
DVD optical drive
Motherboard is ripped out of a HP and is going to be replaced http://h10025.www1.hp.com/ewfrf/wc/document?docname=c02978278&lc=en&cc=us&dlc=en

I have an old ATI Radeon HD 6450 to use whilst this GPU is having issues.

Any help would be greatly appreciated.

So your 6450 is working nicely?
Then maybe your 660 Ti is broken, if its new then replace it.

I was thinking maybe it's to do with the PSU since the 6450 requires no supplemental power but the 660ti requires 2 x6 pin power.

Corsair TX series is just awesome.
Is your GPU properly connected through PSU?

You should probably run a Friends GPU in your Computer to check whether your PSU is good or Broken.
