[A Train]

Right so I recently built the following system and put it together myself.

Intel i7
Gigabyte P55A-UD3R
4 GB Ram
Radeon Sapphire 5770
2x 1 TB Hard drives
windows 7

Now it seems to be running fine, but whenever I render from it or try to rip and convert from a DVD it goes for around 15 minutes + then will suddenly cut to a blank white/grey screen. Pressing the numlock and caps lock do nothing so its definetly frozen. I think.

Now I'm assuming its the graphics card, I doubt its a heat issue mainly because the cards running at around 70 degrees under load. Front 120mm fan bringing air in and a top exaust so there is plenty of air flow in the case. Im trying to source another pci-e card to swap out with the 5770 to see if it still does the same.

Anybody had any similar experiances with this White screen? No error codes displayed, just a blank screen.

Right so I swapped the card out, and it seemed to be going fine. Then bam computer froze. No white screen though just straight freeze. What does this mean?
