Serious problem ..... :(

[RobertGPS]

Hi,

Ive posted a thread earlier. I have build my first gaming PC, but I think it was a bridge too far....beacause I'm afraid I've broken something...

Spcs:

X99 MSI MOBO
MSI GTX980Ti
i75820K
1200w Corsair HX PSU
H100i GTX water cooler

At first my cooling temps were far too high. I accidentally installed the wrong screws for the H100i into my mobo.

I changed them to the right one (which were lower...) and my temps were great! (new MX4 paste

But........ I got 2 times a major FREEZE, just on desktop, couldn't do anything... But I could reset and everything worked.. Until just now....

When I tried to put on the system, I just hear a couple "dead clicks....." The system is TRYING to boot, but it can't....

I've tested the PSU, and it lights up green, so that can't really be it... When I just unscrewed the H100i again, 1 screw was coming up with the cooler...it was 'stuck' with it So i am very afraid there did go something terribly wrong there.... I am VERY afraid the CPU is dead. Of maybe the motherboard..... The motherboard 'on board power switch' DOES light on... don't know if that could mean something.

And one last detail, when the cooler was mounted wrong in the first place, I ran Prime95 and did get INSTANT 95 C degrees... maybe it fried the Cpu? I shut the PC down in 5-10 seconds after starting prime, so it didn't run very long....

Please help :-(

No no beeps,

Cmos: yeah well, I tried clearing cmos buy pressing the clearing cmos button at the back of the case/motherboard.. Just pressed once.

And yes, the smear? VERY strange? It was there from the beginning?

I hate those clear CMOS buttons. Forget it and pull the button battery for 5 mins then put it back and try to boot.

Looks a BIT simmilar... Here it is the standoffs... I just screwed the screwsn there without a backplate, for the 2011 it isnt necessairry to install it...

Also... Read my first post: NOTHING was wrong when I finished the APAC And first booted it, but AFTER I used the other (but correct, I know that for sure) screws to install the H100i correctly, the problems started.... I tightened the screws pretty far, but from my opinion nothing terribly far or TOO much ...

Are you sure the motherboard is in correctly? And there are not any screws loose between the motherboard and case?

 

[QSV]

Dont they have stoppers anyway, so you cant overtighten?

If you have reseated everything, pulled the plug of the PSU for a few minutes and everything else I suggested, I am out of ideas. Maybe a short somewhere. But what causes it? I dont know. Maybe something you did when you changed the screws. As I said, maybe some conductive thermal grease, maybe a metal flake coming from the screws... Check everything closely and blow over it, even the backside of the mainboard.

 

[RobertGPS]

I'm trying the cmos now, battery is out for 5 minutes, I will put it back in and blow and check for Loose screws. Coke back in 10 minutes

You can also try removing all RAM sticks and USB devices.

 

[cdabc123]

remove everything but the cpu and power supply and see if the motherboard will even beep at you. then proceed to adding on component at a time starting with ram. do you happen to have another computer you could test the ram in?

 

[RobertGPS]

Cmos didnt change anything :-(

But, I unscrewed the H100i again and one of the standoffs screws AGAIN just came of the mobo and was 'stuck' to the H100i big thumbscrew..... Maybe I do have to install the backplate? Though I cant imagine this is it....

 

[cdabc123]

have you tried removing everything but the psu and cpu?

 

[RobertGPS]

Cdabc, remove EVERYTHING? Also all cables? All except the CPU4+4pin and 24-pin maybe?

And ofcourse the CPU itself

 

[cdabc123]

yep you can leave the cables in as long as one end is unplug. take out all pcie cards, the ram, unplug the hard drives. you can leave the front panel in though.

Of course leave the CPU cooler installed.

 

[QSV]

No, just the GPU, RAM, USB devices, HDD/SSD/optical drive. Then try to start it again. If it at least starts then (fans start spinning), turn it off and insert the GPU again, start again, if it still works, insert the RAM sticks one by one and start the PC between every stick, connect the drives again, until it stops working again. Then you have found the cause.

 

[RobertGPS]

Ok, ive pulled all out....except the CPU power cable and the 24-pin. Then the same happens: 1-2 seconds the mobo lights on, and then POOF... All out.... 3 seconds wait.....1-2 seconds everything ON and POOF everything off....etc etc etc

 

[tiny voices]

Put the RAM back in and try.

 

[cdabc123]

ok unplug all wires from your psu. connect the green with a black on the 24 pin connection to turn the psu on. then use a voltmeter to check the voltages of the psu.

 

[RobertGPS]

The PSU is a one week old AX1200i with a self test button. When it lights up green then according to the manual everything is fine. And it does....

i would still test it if you can

 

[tiny voices]

It is fine if the self test passes.

The self test DOES exactly what bridging the green and ground does.

Also putting a volt meter on a PSU that isn't powering a systems doesn;t give accurate readings anyway.

ok, i did not know what the test, tested. i use way too much enterprise hardware.


do you happen to have another cpu you could test in this computer or another motherboard you could test the cpu in?

 

[RobertGPS]

No..... I dont.... 🙁 I can go to one of the two big computer stores in my town, they both have a technical service for all pc's.... Returning the motherboard to the online store where I bought it would't work, does it.... No warrenty I guess because I broke it with my screws probably? Or cant they see that....

 

[RobertGPS]

IF it is the mobo of course.....but it almost has to? Doesnt it....

if its a week old i would assume you could just say it was DOA and it could be your motherboard or your cpu ether could cause a problem like this

 

[tiny voices]

It is not the CPU. That is basically certain.

I would remove the motherboard, and reinstall it making sure it is properly on the standoffs. It sounds like you could have dropped a screw or washer behind the mothebroard when installing the cooler and it is causing a short. This is actually very common.
