99% New Sapphire Radeon HD4850 Suddenly Stopping

Hi, I just bought an ATI Sapphire Radeon HD4850 and put it into my PCI-E port. It was running fine until I started my PC the same day I entered the card my screen appeared with a few gray lines and a slightly fuzzy screen.
My specs:
450W Corsair VX psu
nVidia 520 chipset
2gb RAM
- the PC was working well just before it. I haven't downloaded any additional drivers except for the 64bit driver for this card which seemed to be working well up until now. No Windows updates have been downloaded no has any other part been added.
Everytime I start, my PC will BSOD just after the login process.
I have the latest Catalyst Control Center installed.
Thanks to all.
