Ok, I just built a system w/ an X2 4800 and an A8N premier board. Its watercooled and the chip never gets past 37 degrees Celsius, so I know its running cool. I have a 7800 GTX and no overclocking on anything. My problem is that when I run 3dmark 03, as soon as it gets to the "CPU test" the screen freezes, also it did this to me when I switched to the options screen in far cry. Any suggestions? I am running x64 windows and I have all the x64 updated drivers as well. Also, why does my computer not immediatly go to the windows boot screen? It HANGS FOREVER on the "asus" boot screen, then another screen showing the IRQ's, then I have to type a damned password for administrator in order to get to windows? I HAVE A X2 4800, and my centrino laptop boots faster. ANy suggestions? THANK YOU in advance, I know this is alot.
