Hi, my PC keeps rebooting after 11-14 seconds, after i installed my new watercooler: Coolermaster Seidon 120M.
I tried to remove the cooler again, replace the thermalpaste, and and put on the cooler again, but still nothing happens. I had a Intel stockcooler before and it worked without any problems at all.
I build the pc myself in April 2013. And it ran without any problems at all until now :-(

Specs:
MoBo: MSI Z77A-G45
Graphics card: MSI GTX 660
Power supply: corsair CX600
Processor: Intel I5-3570K
RAM: Corsair Vengeance (4x2 = 8GB total)
HDD: Seagate 1TB (Dont know which model)
And a DVD drive: Lite-On

And sry bad english... :-(

Hope you will help me :)

Note the MoBo header usage at about 7 minute mark


That was the tutorial i followed, i watched it before i installed it, AND while i was installing it.
And what do you mean when you say: "Note the MoBo header usage at about 7 minute mark"

Look at the 7 minute mark of the video ...that's where they connected the fans to the MoBo headers..... do you have the pump and fan speeds on the correct headers ? Go into BIOS and make sure that the fan speed is above the minimum threshold ? If it's not BIOS will shut down.

I connected the pump to CPUFAN. And i connected the fan (On the radiator) To SYSFAN1 on my MoBo.
I saw on the internet that the pump needs more power then the fan, so i connected the pump to CPUFAN. I also tried to set the pump to SYSFAN1 and the fan to CPUFAN on the MoBo, without luck. :-(

EDIT: And i cant get into BIOS. And When i turn the PC on, nothing shows on the screen at all. Just black...

Backwards .... You need the fan on the CPU fan as it says in the video. If the pump needs more power, can use one of these:

Is the blue light on ?

Have you checked BIOS fan threshold ?


The Pump lights blue, yes.
And i can´t get into BIOS. :(

You have no BIOS access in those 14 seconds ?

try taking ya stock cooler and connecting its fan to CPU fan header and connect the Rad fan to one of the others. See if ya can get into BIOS.... immediately check temps in BIOS to make sure cooler is working.

Then check minimum fan rpm ....set it below 600 (590)

So, remove the watercooling block, fan and radiator. And then install the Stock cooler like before, when it worked? Or keep the watercooler on, and then connect the stock cooler? I don´t understand.. Please explain more :-)
