GTS 250 installation Problem!

Hey guys

Um I have a bit of a problem I was hoping anyone could help me out with

So I've bought a Palit GTS 250 512mb GPU, plugged it all in, powered it up, its all fine and I started installing the new drivers.

Once these drivers have totally installed I am prompted to reboot so I do.

When the computer starts, it runs through everything fine until it gets to the windows screen showing the loading bar.

Then the graphics card's fan slows down and I am flashed with a blue screen very quickly and a message up the top reading "MEMORY_MANAGEMENT"

After this I wiped all VGA drivers from the PC, and reinstalled the new ones but no luck at all

Is this the PSU, I ran tests on the RAM and all is fine

Im running a CODEGEN 450w, with a q6600, 1 optical drive, 2x120mm fans and 1 80mm, and only the single HDD

My previous card was an 8500gt, terrible I know so I need this upgrade.

If its a driver clash is there anyway I can fix this without reformatting windows???

Any Ideas are very appreciated. Thanks

You only have 16 amps on the 12v rails. You need 26 amps on the 12v rails.

475W PCI Express®-compliant system power supply with a combined 12V current rating of 26A or more

Change that power supply to a Corsair or Seasonic.
