Built a new machine including Intell D865PERLK mb, 2.4 CPU & W2K os. I have problems about 30% of the time when booting, it will keep cycling through the boot sequence & never actually boot. Sometimes it will boot without the graphics drivers. Have to reboot a couple of times until it comes up good. I have swapped out the hard drive & reloaded os but still have issues. Where do I start with swapping out hardware, ram, cpu, mb? Any help would be great.
