Wonky Cooler POST

post #1 of 7
Thread Starter 
Hey everybody,

Long-time reader, first time poster here. I sense this issue may seem obvious for some of you but the nature of it is tough to google.

Intel Core i7 3770k
Sabertooth Z77
Hyper 212 Plus

After installing a new graphics card (Nvidia GeForce GTX 660 Sig2 FTW) my pc will not post unless there is no cooler. Let me be clear, I DO NOT leave the pc on without the cooler for more time than it takes it to post. To clarify, the fan plug is connected while I run these procedures. I made absolutely sure there were no bent bins and the MB power connectors were firmly attached. I even tried reseating all power connectors a few times. I always wear an anti-static wristband.

The backplate is properly attached. Ram configuration does not matter and both sticks check out fine in memtest (Mushkin Redline 1866MHz).

One thing I noticed that was strange before this problem arose was that after I installed my new nvidia card I turned on the pc to install the driver. I had the hdmi cable attached to card obviously. I got the driver to begin installing. It failed saying it needed an internet connection to install (newb mistake woops) then the pc shut off, turned back on again with red cpu_led.

It seems the pc only posts (after that it boots everything ok) when there is no cooler. If I install the cooler I get a red cpu_led. I tried using utmost gentleness every time. Once or twice I got it to boot with the cooler installed but without fans attached. After I attached them the red LED comes back. I figure something is shorting somewhere. That would be my guess. I have reseated the cpu multiple times but to no avail. I checked to make sure the board was clean and nothing was touching with flashlight and magnifying glass. I tried attaching the cooler lightly a few times too, with no screw fully down all about 1/2 or 1/4 turn from fully secured. It's confusing me what would be set off by such delicate touching around the cooler?

Should I just invest in a new cooler? Or could it be my motherboard?

I am sorry if I am missing something.

Please help.

Are you saying that the computer will post and boot with no cooler attached?

Sorry, but I have to ask, did you use thermal paste? Id so, how much?

Yes. But to reiterate, the 4-pin connector for it is attached during this. I've never let it get that far with no air cooler though, too risky. I think I can assume it would boot from my testing experiences (It got past the post screen with no cooler attached). It's just that if I attach the fans to the cooler or "nudge" it the wrong way I get a red cpu_led.

Knew I was forgetting something... Always use a pea-sized dot dead center when applying thermal paste on the cpu; clean it before reseating of course. I made sure none got in the socket as well. It is clean. Checked with flashlight and magnifying glass.

Welcome to forum! thumb.gif

The times I've seen systems not boot similar to this the cooler / mount was shorting out / touching on something. Maybe fan clip is touching new GPU?

I'm assuming this problem started with new GPU and BEFORE you removed cooler, CPU, etc.

Have you tried removing GPU... setting up system the same as it was before the problems to see if it works?

Thank you for all the help so far.

The fan clip is not touching the GPU. They are pretty far apart in the case. I'd say about a few inches. In fact, nothing from the cooler is coming into contact with the thermal armor or any other part of the board.

Correct. I must mention that I got a few cpu_leds building and upgrading it but reseating the cpu fixed them every time. For instance, I could improve upon the cable management and it wouldn't happen again. It was never this frequent and unexplained.

Yes, I still got a cpu_led. Then without changing ANYTHING else I removed the cooler and tried to boot again. Worked like a charm.

I'm gonna need to bump this and apologize for my previous stubbornness. I did, in fact, set up the system exactly as it was before. The clips did not snap off...I guess I just became frustrated through some late-night retro shopping rolleyes.gif

And everything is working as it should now?

Maybe try new GPU in a different slot.... Just thought of another possible cause and I know it sounds stupid but if the PCI-E power cables are not plugged into GPU system can give same symptoms you had.
