I've just fixed a dodgy system for someone and it all started going wrong when they put a new graphics card in, turns out the psu was only 200watts so i'm guessing the HD got fried because of this. However I need to confirm the graphics card is working 100%
is there a burn in test for graphics cards similar to prime95?

Problems do not always show up immediately(or at all) under light use because either that part is not tested under light/ordinary use or because the higher temperatures of extended use can cause the issue amongst a few other potential reasons. If you can accelerate the equivalent of several weeks of normal use(beyond which point you might have to rely on manufacturers warranty rather than dealing direct with the shop for a simple refund or replace) into a much shorter period then in some cases it can make sense to do so.
