Asus rampage II extreme not booting (powering off)

[Dylme]

Hi every one,

I have a problem. I was given a Asus rampage II extreme with 3x2gb Kingston hyper X 1600 and a 1gb Asus grafics card (don't know more about the gpu)

I powered it all with a corsair vs550 but I can not star the pc it starts to boot and immediately powers off. One time it got to show on screen the rog symbol but immediately powered off again.

I m noob to this OC thing and I can not find the solution.

Did you try clearing CMOS and then booting? Did this mobo work for the previous owner?

Yes I cleared the CMOS and it does this.
if I power up the psu and press the power it does nothing. Only after clearing the CMOS it shows some life... Fans start to spin and the automatically stop again. The previous owner didn't use it for a long time but it was working

Did you put all the RAM sticks in the white slots?

Also look for a memcheck button, press it for about 5 seconds while the PC is off, and let it run (the PC will reboot a few times).

The ram is all in the blue slots

I'm pretty sure (didn't get a chance to look at the manual yet) that you should put it all in the white slots, as those are the primary channel.

One more clue. If I leave it with the psu powered and leave it resting for a while it then stars and the start up there's is a message saying that NB is overheating then it starts and powers of just before entering Windows. If I try to start it right back it doesn't go as far...

Then your northbridge/mosfat is heating. Is the board tinkered with or nicked in any way? Can you show me a picture of it?

hi ShakedG i noticed that the heat sink in the NB is loose... what can i do or what do i do about that??

 

[ShakedG]

Can you take a picture?

I can't really see if it's loose, but it seems off that there are thermal pads coming out of the heatsink (they may have shifted). My advice - take it off by unscrewing it. Then reapply the thermal compound (you can go to a PC hardware store and get thermal pads). Then reapply the heatsink, carefully screwing each screw a bit, then the next one, then the first one a bit more, and so on.
