Had some problems with uninstalling the drivers of the failed DTV card which led to more uninstallation issues and I actually screwed up something in the registry trying to uninstall Everest which decided to start playing up, so eventually had to format my hard drive and re-install vista completely! Now that i've done this everyhting seems to be working better and things that weren't working are working now.

Also I have much more hard drive space free than when I took delivery (half my 150GB raptor was used when i received the pc!)
So now i can properly start benchmarking, I'll begin with 3dMark 05/06..stay tuned..!
(Still don't know who makes the gpu though -mystery. However i saw a pic of a PNY GTX whick looked exactly the same black/green case except PNY logo where Nvidia logo is on mine)
