It's unlikely that it is the card - but it is not an impossibility.
I had very similar symptoms with a 4890 that turned out to have a faulty voltage regulator on the card itself. The voltage would fluctuate wildly, even spiking over 2v which is way out of spec
At the time this issue drove me mad trying to find the culprit and it was actually by sheer luck I noticed it while monitoring the card with GPU-Z
My screen would go black (sometimes grey, red) - the fan ramped up to 100%, audio looped etc. Eventually it got so bad that it would do it at the desktop and then even in BIOS.
I'm not saying that this is what's happening to you - but it's a possibility.

I think it would probably be a good idea to start with RAM, and test it so we can get a better idea what we are looking at.
No point running out and buying parts you do not need.
I'd be inclined to suspect the PSU as well (insufficient amps on the 12v rail) or something inside the PSU has degraded to the point where it's being pushed too much under load and the lockups are the result.
But as WM said, there's no point in rushing out and buying anything until you have narrowed it down by eliminating other potential culprits.
The card should also be displaying one or two Red LEDS on the back of it when it's locked up. Depending on the lights, they can sometimes help point you in the right direction.
