Yes, if the power supply was insufficient, then you replaced it AND
knew that a problem was solved. But only if using the meter. If the
power supply was sufficient and you replaced it anyway (shotgunning),
are those new symptoms an additional problem or a new problem? A new
problem created by replacing a good supply with a defective one OR a
new problem by replacing a defective supply with another defective
supply. Without measuring the power supply, nothing was known
accomplished.

Well all I know is I had the occasional stop 7B bluescreen and the first time it happened was right after I replaced the dead ColorsIT 480W PSU with the Q-TEC 500W, the first bootup with this PSU showed the stop 7B bluescreen. Then a few weeks later I tried to power the system with what turned out to be a faulty Seasonic S12II 430W - the Q-TEC was laying dormant and when I connected it back up the very first boot I got the Stop 7B bluescreen again - it seemed more then coincedence that when the Q-TEC had been removed completely from the system for awhile and was powered on the first time I got Stop 7B Bluescreen.

Add to this the complete system freezes I started getting in Windows and the time the power just went and the machine restarted and I think I have enough there to suspect a PSU issue as well as the gfx related problems. In anycase I now have my Gigabyte 8800GT OC set to 700/900 from stock OC of 700/950 and I am pretty sure the black / purple screen problem is gone forever. I am using ntune to do this.
