I got this pc, like begin 2004.
In September 2005, I bought a 6800 and replaced it with the 5600 fx I had before. No problems yet.
With christmas 2005, I got Sounblaster Audigy 4.
And then the 50% CPU Usage showed up, a month later.
But the funny thing is, that I had a poweroutage, while my computer was on. When I turned my computer on, the 50% CPU Usage showed up. But I have a secured powerconnection.
And then when I was going to reinstall windows.
I don't think that I can reformat the drive. Because I have a windows on a cd, but not windows itself, it's like, I only can use the windows disc, on this computer. Because the brand's name is printed on the disc. Medion is the brand.
