Did you check temps in the system? Did you try running on half the RAM?

Has it done this as soon as you re-installed Windows and the drivers? Or did it work for a bit then started going blank? Try increasing the max power setting in the driver options.

May be a video card or power supply issue, you would need to test the card in another system that can run it or test another card in your system to rule things out.

For testing with issues, first thing you should do is set everything to stock speeds if it's overclocked. No way you can trouble shoot when you have another variable like an overclock to deal with. Want to rule out everything and have the system on the basic setup.
