A clean install of Windows Vista did not help at all). As far as I can tell, the rest of the PC is in good shape, and is still quite powerful, so it seems a shame to just dump it for parts. It currently has a single Radeon HD 3870. Do you think there is any chance of replacing this with a very cheap replacement. I don't intend to spend a lot of money on a good graphics card - something right at the lowest end of the scale will do, especially as the PSU is still stock 375W I was having a look at some of these: http://www.scan.co.uk/shop/computer-hardware/all/gpu-amd/radeon-hd-5000-series-pci-e Do you think any of these would work? I don't know very much about hardware. Thank you very much.
