I'm totally confident in my ability to install a graphic card and RAM, the only thing i'm worried about is after i take it out to put into my computer, if i have to re-install windows to get it to go back to intergraded graphics and only 512 RAM.
if you do that make sure that you back up everything and anything that is impoartant on you computer... i learnt this the hard way..... 5,000 words of coursework... just because i didnt bother to back it up properly...
