Hi RunenBlut! Geiler name! Is the PC a new build or it has been running already for a while? What is exactly happening when you push the GO button! Did you try to disconnect some of your peripheral devices and form the PSU and tried to boot than?

Below in my signature there are some helpful links and how to build a minimal DFI build. Check them out! :cool:

ok, i just built my system up on the table (minimal built).

same issues...

the fans just start running for 1 sec, the fanled also flashes and then dies.

 

the system was already in use before, just the dfi is new.

I had the same problem with my new Tagan 900W see LINK after swapping the psu over with the psu out of my second system Enermax Noisetaker 600W everything back normal.

I read some threads that user have been having problems with the new Enermax Liberty some working and some giving people the cold boot problems like i had with my Tagan.

 

Here is a thread were the Liberty 620W is giving users the cold boot problem

This might be CPU failure.

You can tell if it's the CPU by removing the CPU, then try to boot.

If your system stays powered up fans spin, try another CPU

If your system reacts the same way without the CPU then the problem is something else.

 

I had the same problem, I had a dead CPU

RunenBlut has pretty much the same rig as me, but mine is a fresh build. Sometimes for me the comp will boot, but this is only when the PSU has been switched off for at least 20 minutes.

 

So I have managed to start installing windows (tho I did get a blue screen at one point), however, if I were to turn it off, i'd have to wait an age for it to work again, and it has been known to shut itself off all of a sudden.

 

I think i'm gonna have to get a hold of another PSU and test it out
