Hello everybody, yesterday I picked up my graphics card. The last thing I needed to finish off my computer.
The graphics card is a EVGA Geforce GTX 660TI +FTW 3GB
My power supply is a seasonic 660W x series.
I have a samsung 120gb ssd as well as a 2tb hdd and 2 8gb ram boards
and a standard optical disk drive.
After installing most of the software for the graphics card I then turned my computer off and installed the card and proceeded to turn it back on.
After it turned on I then started to install the software, slightly though I blue screen flashed on my screen then the computer shut off completely.
There have been occasions where I have tried turning the computer on and it boots slightly then just dies. Do I need to invest in a new power supply or is there something more I should know?
Thanks for any answers I really am thankful!

That is great power supply. It has enough power to SLI those 660's.
How about temps? Have you checked temps, both of GPU and CPU?

Are you sure everything is plugged in correctly? Double check that first.

Check your CPU heatsink if it is firmly in place. Overheating may cause this kind of behaviour,

Also it is not impossible that your PSU is bad, or mobo.

Are you using the 6pin pci-e power connectors from the power supply or the molex to 6pin power adaptor that comes with the card?

I'm using the 6pin pci-e power connectors that came with the power supply.

I took the gpu in yesterday to make sure it was fine and it was working. This is my first custom build so the wiring is no doubt sub par. I think I might take it to the shop where I brought the parts from so they can re-wire everything making sure everything is where it should be. Do you think that it would be a good idea?

If you are sure that you have connected everything best you knew then you should go to computer shop an let them take a look. It may be faulty hardware.

Hey guys, thanks for the help! It's now solved! Turns out it was the motherboard's bios that needed to be updated. Again thank you for all the suggestions.
