SOLVED: No POST when RAM is in!

Ok so ive been working on this PC for the past 2 weeks with no results.

Specs:
i7 3820
Gigabyte Z77 UD3
Cosair HX750
CPU Cooler: Hyper 212 Evo
Thermal Paste: Artic Silver
MSI 560 GTX Ti Hawk Edition
Patriot Gamer 2 Ram 16gb (4x4gb) 1600mhz

Ok so whats been happening is... Ive started building a PC, installed it all and no display/post.

So i went testing things (as much as i could) and the RAM was working fine in another PC (all sticks).

So i returned the motherboard thinking it was defective, got a new UD3, started working on this and get the same problem.

The problem is, when i have nothing but PSU, CPU and Mobo (no RAM) i get Continous Short Beeps, as soon as i put 1 Stick of RAM in, i get no beeps, its silent.

I have tried different RAM in it, Including Rip Jaws X and a Cheap Brand of RAM. Same Problem.

I Upgraded the PSU from Huntkey 650w, to a HX750, because i thought it might be a problem, No avail.

Any ideas?

  1. Tried a different PSU, or video card?
  2. Im not even bothering with GPU atm, since i cant even get it to that point.

    But yes ive tried a 260 GTX, 5500 GTS (doesnt need PSU Power thats why) and my 560 GTX Hawk.

    Tried 3 Diff types of PSU including a Huntkey a Cosair 650 and hx750.
  3. Wonder if it could be the CPU... Not really much else to chekc
  4. I know, thats the only thing i havent replaced during this Build... and all the same problems....

    BUT! in saying that...

    Why would it Beep when no ram is in, But when Ram is in, it does nothing?
  5. The beeps are a code. Basically saying that there's no ram lol.

    Do the fans lights etc come on?
  6. Unless your shorting out the motherboard... Have you installed motherboard on the spacers? (and not directly screwed to the case)
  7. Check if cpu fan running. Also check all power connection to mobo again. It can be cpu.
  8. ^^ how do you check if the CPU is running when the comp isn't posting?
  9. I mean cpu fan. Its typing mistake. Thanks.
  10. CPU Fan running Perfectly.

    HDD Spin (when plugged in), same as Case Fans, and the DVD Drive.

    I cant short it out, since its on a breadboard (unless i can short it out on Cubboard).
  11. Did you check connect your display correctly? But i am still thinking its cpu.
  12. Yeah i tried 3 Video cards and 3 diff monitors.

    And not only that shouldnt the PC Do different beeps to detect no GPU? instead of going silent when the RAM is installed.

    PS: Mobo is a x79 not a z77 previously said.

    i'm having the same problem as you, on my i5 3570K build with a Gig Z77 UD3H

    my thread is motherboard/bios section... if you happen to get it solved, please drop in on my question thread with the answer.
    if i solve i'll do the same with you !!!

    guys had me put 1 DDR3 1600 mem chip in but i'm still not getting anything on screen or any kind of post.. showing codes of 15 & 19 now..

    Good Luck

    ps; i thought the cpu fan wouldn't run until temps dictate it !!!

    ....
  14. CPU Fan "Should" Run slowly.. at all times. until where it speeds up.

    Sometimes there is no beep for cpu error, depending on bios version. What is your mobo model name?
  16. Gigabyte x79-UD3
