It looks like a bad driver install, an inadequate PSU or a bad card. I'm more inclined to think it is the latter.
Try older drivers. If that doesn't work, try getting a new PSU. If the Cooler Master PSU you have is from the eXtreme Power range, replace it ASAP. They are crappy and don't last long. Get a better one from Antec, OCZ, Corsair, FSP, Enermax, PC Power & Cooling, Seasonic, Thermaltake or Silverstone.
