I bought a new MSI Geforce GTX 780, At first the computer booted, I reinstalled the drivers using the clean install by Nvidia, rebooted my computer and launched Battlefield 4 Beta, after loading for about 5 minutes my computer suddenly crashed, just shutting down completly, I thought my PSU had broke, but when I took out the new gfx card the computer worked again, and it works with my old gfx card as well(An Asus GTX 670)

PC Specs:

MSI Z77A-S01 ATX

Intel Core i5 3570K 3.4 GHz

Corsair 16GB (4x4GB) CL9 1600Mhz VENGEANCE LP

NZXT HALE90 850W 80+ Gold Modular

Thanks in advance for the help.

I'll type down EXACTLY what I did.

I uninstalled all GFX drivers with my old card in.
I shut down the PC and swapped cards
When I launched the PC it was weird, it started but then shut it self of after 2 seconds, I launched it again and it started but I had a black screen.
I thought it was a glitch so I opened my PC took out the card and put it back in.
The Pc the launched fine, so i installed new drivers usin the nvidia CLEAN install.
I then rebooted and launched Battlefield 4 and after about 5 minutes of loading screen the PC just died, completly shut off.
When I then tried to start the PC again it wouldnt start at all, completly dead.
I then opened the PC and took out the new card, the PC then started fine.
I put the card back in and it woudnt start again, took out the card and put my old card back in and the PC is now running fine.
