Hello, I have just upgraded my motherboard and processor to the 7VT600 1394 and the AMD 3G processor, all other components remain the same including my hdd and my XFXforce FX5600 graphics card. The system boots ok but any intensive graphics games like MS Flight simulator 2004 fail to load, whereas previously there was no problem. (so why upgrade you might well ask ). So I bought a new 80g hdd drive to do a clean install, fdisk works ok but during the installation of windows xp I get a blue screen error message saying windows is now shutting down as there is a problem and continueing might cause damage to my pc. Any help would be appreciated. Regards Frank
