Just upgraded cpu, mobo, and ram. computer wont post.

So I upgraded my i5, old gigabyte board, and misc DDR3 ram, to the specs you see below. My computer wont even post now. I've tried resetting the CMOS but it didn't work. My new mobos manual says I need to replace the battery. Do I actually have to do this? And if so, Could I use the old battery from my old gigabyte mobo that the previous specs worked on? I also tried using 1 stick of ram and that didnt work. However, I didn't try using every stick of ram in every possible slot. Also when I plugged in the sata cables, I put all of the sata cables from the hdd on the sata ports on the left side. Then I plugged the ones from the ssd and the dvd drive to the ones on the right side. The RAM and GPU is firmly in there so that's probably not the issue. The system worked perfectly fine before this upgrade. Any tips would be appreciated, thank you!

Specs:
GPU: Nvidia GTX 970
CPU: Intel i7 6700k 8M Skylake
Mobo: Gigabyte GA-Z170XP-SLI
RAM: 16gb of Corsair Vengeance LPX DDR4 3000
PSU: Corsair CX750M
Case: Thermaltake Chaser Series Chaser MK-I
Storage: 1 TB HDD(dont remember brand, this one has os on it), 240gb OCZ ssd, and super writemaster dvd drive.

  1. Do the fans all turn on?

    Yes, all the fans and led's power on. However, they only stay on for about 10-30 seconds before turning off, then on, etc.. The system wont post though.
  3. Did you use the system speaker? It should give a beep code or there should be a digital number error code on the board. This will help diagnose your issue

    I don't know if my system even has a speaker. The audio on the motherboard is powered but no sound plays when I power on my system. I haven't tried jumping the mobo yet though ( shorting the 2 jumping pins with a screwdriver with the system off). Again, I'm not sure if my system has a speaker as I normally use a usb headset.
  5. No on the headers where you jump started it there are pins for an odd looking speaker. Should be an odd looking speaker in the stuff that came with your board to put on the headers. This will probably tell you the issue.

    The only cables that came with my board were an sli cable and a bunch of sata cables.
  7. Might want to bench it, may be shorting out or just missed something, wrote a guide that may help here:

  8. Im gonna try and leave the battery out of the mobo overnight. See if that might fully reset the CMOS.
  9. Only takes a minute, unplug PSU, pull battery and reinstall after a minute or so, plug in and start up.
  10. All but 2 standoffs and screws and underneath and screwed into the motherboard. Do you think that might be causing this issue?
  11. Could be, yes
  12. I'll put them in tomorrow and will tell you if it works suddenly.
  13. Sounds good!
  14. Didn't work, We werent able to put 1 standoff in because there wasnt a hole in my case for it but we did put the other one in and screwed it in. There was also a standoff in the wrong place. Even after all this it still wont post. I even left the optional sata cables for the front panel hard drive slot unplugged. Don't really know what to do at this point.
  15. Did you check the socket for bent pins? If benching didn't identify anything, without getting my hands on it don't know :(
  16. I put my old mobo cpu and ram back in and its working. I think it's a bad mobo as it's slightly bent and one of the leds on the mobo doesnt work. Will probably return it to newegg to get a replacement and see if that one works.
