Need help! too much "physical" pressure on CPU by Super Mega?

post #1 of 9
Thread Starter 
Hey guys,
I need help!
I've been using current system with no problem for about 1.5~2 years, until I recently bought Prolimatech Super Mega to replace the stock CPU cooler.
If I install Super Mega as instructed(tighten screws on the bracket as I suppose to), system does no boot. I have to loosen up screws on the bracket(loosen up to the point that I can move the whole heatsink over CPU a little without totally removing the bracket) to make it boot. I have to loosen the screws so much that it actually feels like I'm just topping Super Mega over CPU.
This persists even if don't overclock anything and remove all the parts except RAM, CPU and CPU cooler. (I can check if it boots or not without a graphic card)
I took out MB out of the computer case, thermal compound is applied properly, and CPU temperature stays between 36~42 degree celcius when idle at room temperature of 23c(74f.)

Below is my system after removing all the parts except the necessities.

CPU: i7 920 D0
CPU Cooler/Heatsink: Prolimatech Super Mega
MB: ASUS P6T
RAM: G.SKILL Trident F3-16000CL9T-6GBTD
PSU: hec Raptor 1100CM(1000W)
TIM: Arctic Silver 5

Try taking the mobo out of the case, the tightening might warp the shape by a slight bit so that it touches part of the metal and shorts it out.

I did take mobo out of the case, actually using it that way for a day now.
But the problem still persists in the same way.

That is a very odd problem. I really don't think there's 'too much pressure' on the chip, I'd have to stake my guess with the previous poster. Maybe it's a grounding issue.

Edit: ninja'd. Perturbing.

hmm I dont know...then it should have worked fine after I took it out of the case, cleaned, and putting it on the cardboard. I'm really confused.

this exactly also happened to my P6T, I forget how I fixed it. I dont think I ever did but just sold it....

anyway, even very low pressure should give a goof enough mount on the board if its sitting flat. in a case its a problem...

Did you torque the screws properly, i.e., opposite corners, couple twists, switch, etc? If one side of the sink came down first, it could cause bad contacts with the chip's pins and cause it not to boot.

Other than that, you've really stumped me there. If you're patient I'm sure a bunch more people will blow through here tomorrow when everyone wakes up.

Well, I tried more than 10 times with much caution, but it dosen't seem to solve the problem...maybe the problem is on P6T? I guess I just have to wait for answers, thanks anyway

this IS a board problem btw...I would also try resetting CMOS, as well as checking the socket for bent pins, because if one is bent, when you tighten it may cause a short & stop the board for operating.
