First - some people are right about the virus updates etc... but if all that is ok....then, I think you should simply start by getting a new piece of memory. I have had both pc133 and DDR cause this to happen on AMD Motherboards. Swapped out the memory and they were fine. Memory is cheap! The other obvious thing to check is to make sure your motherboard is set correctly. I have had a few people bring me their home built machines running AMD chips at 100 bus when they should have had them set to 200 bus etc. Check it all very carefully. Double check the stamp on the CPU too and look it up to make sure you have the right settings for that chip. Good luck! And let me know if it helped.
