How to test a CPU?

I recently purchased a I-7 4770k for my first computer build. The first time I tried to boot it, I had motherboard issues. I ended up replacing the Mobo, but kept the CPU. Never did get it to boot. I ended up frying everything attached to the motherboard except for my SSD and Ram.

Putting the parts into a new system and it was working great, until I tried to use a USB hub that was fried from the first MOBO.

I replaced everything on the build and it's all working great now- however I am curious about the CPU. It was brand new in box, and for all I know still works. However I do not want to put it into my system, for fear it may damage something.

I get a lot of mixed answers on the question. Everything from "you can't damage anything with a bad cpu" to "you'll damage it all and cause world war three."

Regardless, i've got to know if it's O.K.

    If you fried anything, frying comes from a bad PSU or mobo. You could have fried your mobo with a bad PSU, and fried your CPU with a bad mobo. Definitely try to tell Intel about this issue, and get them to replace it for you. It can't hurt. But it definitely sounds like you had a LOT of issues...

    and
    Memtest www.memtest.org

    The INTEL test will confirm any issues with the CPU. It will stress, and run a serious of commands to verify all the parts of your CPU. Running MEMTEST requires a USB or DVD burn and possibly for you to change the BIOS boot order.

    *run MEMTEST first. If it was defective then the CPU could also report errors when running the Intel test.

    The issue stemmed from my original MOBO. Lol. Not really a lot of issues, just from the same root issue.

    Quite possibly damaged the CPU with the old Mobo, but like I said.. I want to get it tested lol.


    My whole point here is that I do NOT WANT TO PUT IT IN MY PC! I can't run tests on it if I don't plug it in. Kind of curious if there's a "tester" you can buy similar to a PSU tester or the like. I just don't want to fry a mobo because the CPU is bad.

  6. Hey,
    I don't think you would fry a motherboard with a bad CPU.

    I've never heard of anybody frying a system with a modern defective CPU.

    I've encountered them before and it simply prevented the PC from starting or depending on the model I might get an LED or digital code displayed telling me the problem.
