Problem with my new 6750

So I replaced an old 8800GT with an XFX 1GB 6750 last night, and it was working well and saw a huge increase in FPS. I saw some people say that the only problem might be a power supply problem. My PSU is a 750 Watt, so I just kind of assumed that the voltage would be ample as well.

Anyway, when I woke up today, I saw that my screen was horribly artifacted. A reboot made it okay for a little bit, at least enough time to check the temperature of the card and it was pretty low, but then it started artifacting again and then blue screened. Now it almost immediately goes to a blue screen upon entering windows. So I put the 8800GT back in and it's working fine so I can ask this problem to the PC board.

Anyway, this is my power supply voltages and stuff. Not sure of the manufacturer, but it's whatever they used in stock Dell XPS's about two-three years ago.

Does anyone know if low voltages are causing the problem? If so, what do I need? And if not, what else could it be?

I very much enjoyed the increase in FPS and would like to keep it...

At this point, I would suspect the 6750, as the PC works with the old card.

As would I. I was hoping that someone might be able to look at the PSU numbers in the picture to verify that the PSU is likely not the problem. If the card is defective, that's fine and I can just exchange it. But I don't want to exchange it for the same card if the PSU is actually the cause of the problem.

I looked at the picture of the PSU label, and if you can trust the listed numbers, it should have no problem powering the video card. According to the label, it has a max of 61 amps available to the 12 volt rails.

You DO have the extra 6-pin PCI-e power connector plugged into the card, right?
