Computer won't boot, just upgraded CPU Cooler, did I fry CPU?

My computer was working fine earlier today, but I think the CPU may be fried now after upgrading its cooler. I have a MSI P67A-C43 (MS-7673) motherboard with an i5-2500k. I upgraded its cooler to a Hyper 212 Evo and then put the computer back together. I powered it on, it turned on for a split second and then it turned off. I realized I hadn't connected the CPU cord from the PSU to the MB. I connected the cord and powered on. I get a few normal beeps and then 5 error beeps. My monitor's display is blank and remains blank. CPU fan spins normally and 4 lights on the motherboard above the CPU, under the text "Active Phase Switching", all light up. I assumed that these lights referred to the CPU cores' activity

So, did I fry my CPU? Not sure what else the problem could be.

I need this computer working ASAP, classes start on the 7th and I need it for applying for internships during the rest of break.

  1. Start by resetting BIOS/CMOS and try again.

    Just took the CMOS battery out and put it back in. Same thing happens. 5 error beeps and no display. What's the likelihood that this is fixable/I forgot to do something when putting it back together (don't think this is the issue)? Really don't have the money for a new CPU right now.

    That's what I feared. Not sure how it happened though. The only thing I wasn't sure about when changing the cooler was using a coffee filter to wipe off the old paste, but that seems to be considered safe, so I'm not sure what happened.

    Thanks for the help.
  5. I removed the cooler and put my old Zalman one that I had on earlier. CPU works fine now and computer boots without the 5 error beeps.

    What could I have done wrong when mounting the Hyper 212 Evo that may have caused this? I would still like to mount it.
  6. Based on that I would look at the mounting. Looks like it was not cooling the CPU.
  7. I took it off and reseated the Hyper 212, but I'm getting the error again. Backplate looks good, only the green non-conductive material on it touches the MB.

    I can't figure out what's wrong. You can't tighten the center screw or do anything with it, other than placing it in the hole, right?
  8. Similar http://www.youtube.com/watch?v=hSq_xbxsm7Q just check if you are getting a short with the backplate.
  9. Just checked it. Don't see anything wrong. I'm going to try and take some pics of the backplate and the mount and uplpoad them.
  10. Well I recently installed the 212 cooler on an i5 3570k and i7 3770k...


    since others suggest it's not cooling the cpu:

    Did you peel off the sticker on heatsink?

    did you mount the heatsink properly using that "X/cross retention bracket"... if i remember correctly it should have small "grooves that will seat a pin from the heatsink" ... i think there's a pin sticking upwards from the heatsink for the bracket's hole/groove
