So, I turned my PC on the other day, only to discover: no picture. So, that's probably the graphics card then. Assuming it is (I am having this looked into), I'd like some recommendations for a mid-range type replacement.

Specs on the rest of the PC are quad-core 2.4 or possibly 2.6 (I don't actually remember and now I can't check) CPU and 2 gig of ram. I don't really want to spend more than, say, £150.

My last one was a nVidia 9[something]00 (I don't remember this, either) and annoyed me by being a) very noisy when you played something graphically intensive and b) Collecting dust like a motherfucker and then overheating (these two facts may be connected). If I had one that did not do this, that would be good.

I haven't paid the slightest bit of attention to PC hardware for about 2 years, so I have no idea what the current state of the market is.
