Hi, got a problem with my desktop computer it only boots up so far, comes up with a blue screen with rows of red stripes down it and then eventually stops trying and comes up with 'No RGB output' - I've read it up on Google and it sounds like the graphics card is knacked - I've taken it out and the cooling fan was clogged up with dust but looks ok - cleaned it up and replaced and made no difference. Just ordered a new card off Fleabay - its the same make as the u/s one ' Asus' make but is obviously a different model. The new card will probably need a new driver to operate it when installed but how will I install the driver if the computer still will not boot up with the new card in or will the generic drivers in Windows allow it to work until I can install the correct driver? Any help would be appreciated.
