Hi, i have been working on computers for about 5 years and never had this problem. Ever SINCE i built a computer in 2006, i have had a problem with it reporting boot failure and system registry problems. I have swapped out RAM, power supply(after failure), motherboard, Video card, and gone through 2 hard drives, and it still comes up. I have also switched xp for vista, and it KEEPS on reporting. The computer works for about 2 days after i reinstall everything. My question is, could the Processor be causing a problem like this, or could my luck be that i get faulty hardware

If the above is correct, seems to me that the probabilities point to the CPU as the error source.Ya thats what the really weird thing is, and you wouldnt think it would come up with an error like that. I am ordering a cheap 939 processor to see if it makes a DIFFERENCE. I would be stumped and trash it if the processor is not the problem. lolI guess that it could just be bad Karma

Post back when you get your new CPU.

Best of luck!The Computer is running flawlessly with a new AMD Athlon 64 4000+. Great! Thanks for posting back!
