There are drivers that XP will not update for us. I'd start with the motherboard chipset drivers (intel.com) and then graphics, audio and finally run DXSETUP again.
I recently upgraded to a Core2Duo from an older AMD CPU. The only components carried over were my hard & floppy drives, power suppply, and fans. I have been a little bit underwhelmed with the overall speed of the system, but most annoyingly, the frames of windows remain when I minimize them. The contents disapear, leaving white backgrounds and the blue frame. This happens with various programs, I have not discovered any particular pattern. Since I have new: CPU, MoBo, RAM, and Video Card, I was wondering what sort of defect might cause this issue. I've heard several answers.
