I built a system with an Intel MB D865PERL and had a freeze up problem when I inserted a CD and the auto run started. I then changed out the MB to an Abit I7. Checked the memory, added 1/2 then the other 1/2 and had the same lock up. I increased the voltage to the memory and changed out the power supply. I tried two different DVD-ROMS, one a USB and one an IDE (one at a time) and system still has a freeze problem. Three clean installs of Windows XP home later, I still have the same problem. Now the CPU is the only common part between the two systems that freeze. Is this a problem that can be caused by the CPU? I have run out of ideas.
