My experience with this CPU is that at this age it's easy to overheat and see those errors. Do your yearly cleaning of all heatsinks, test the fans and run this memory test -> MEMTEST86. Only ZERO errors is acceptable.
Have an old computer which now has 98SE installed, with no problems. It has a Biostar Slot A mobo, with an AMD K7 chip, FX 5700 video card, and 768meg SDRAM. Tried installing XP Pro from clean boot, but will not allow same...numerous errors. Is it possible to update the BIOS to allow XP, or should I just re-install 98SE, and quit wasting my time. I have new machine with XP Pro installed, as well as laptop with Media Center, so it is not needed. Any help would be appreciated.......Dobby.
