I think my CPU is defective. Should I put in a new one or go to a PC repair shop first?

I can't get anything to display on my PC. I've had two Z77 Extreme4s now that don't display and have error code 53: no RAM detected (and I've tried multiple sticks including another type) and it still doesn't detect RAM. This is my second Z77 and it's still not working. Should I open up my other i5-3570k that I was going to sell or see a repair person first to make sure it's the CPU that's defective? (I'm not sure how expensive they usually are).

  3. Are you sure you pushed the sticks in hard enough? You need to apply quite some force, untill it clicks into place. that's all i can think of atm

    I think so. If I press any harder, I'm worried that I'll break it.

    you have to keep pushing untill you hear the 2 clips at the end of the dimm slots snap back into place. after that you're not supposed to be able to pull the sticks out without opening the clips. I was worried about breaking it as well ^^

  7. have you tried using just one stick of ram?
  8. did you try pulling the video card ( removing ) and booting with the on board video?.......... monitor cable attached to the back of the motherboard...

    I tried using onboard video, but I had the video card in. You need to take it out?

  13. can you maybe post a photo of the current state of your motherboard, with everything attatched (including ram and gpu)? my friend had the a very similar problem with the same mobo and it turned out he forgot to connect a power cord somewhere
