i just built my first shuttle system and had a x1950pro from my old system, its got a zalman cooler, which i thought was a bit big for the shuttle but tried it anyways, it fits although its a very tight squeeze in there. Went to install windows, it crashes halfway through now my intial thought is the graphics card is over heating but just wanted a second opinion before i contacted overclockers for return and if i was to get an alternative what would u recommend?
