      I contacted a computer specialist who informed me that the CPU was supposedly sold with defective because hardly fault this equipment in such a short time (about 2 months since its purchase).

          Thanks for joining the Processor community.

          I have been reading this type of message crashes the computer because an over clocking feature is enabled on your computer.

          You may need to access your computer BIOS, advanced features and performance options and see if your computer comes with over clocking options that you need to disable.

            I have a very similar problem with a Dell 8700 I purchased in October (and barely used because it's my daughter's PC), but it gives me both of those errors on startup. It will reboot in a loop forever and never start the OS. It's never been overclocked and resetting the bios to defaults does nothing. Dell has sent a tech out to change the motherboard but the problem continues. I finally got frustrated with their lack of tech support (it's been close to a month and multiple hours on the phone with people that know less than I do) and replaced the CPU from another 8700 I own and the broken computer boots fine. It's definitely a CPU issue, however, I don't know how to prove it. I've tried booting from a USB with the Intel Processor Diagnostic Tool and it reports everything is just peachy. Except for the fact that it won't boot the damn OS!


            I have to say I've never had a processor issue like this in the 25 years I've owned and worked on computers. It's quite frustrating. I only hope Dell will replace the CPU or else I'm hosed.
