crash System crashes more or less randomly

[nysnys123]

Hello everyone!

I recently sold my old FX8350 and bought a 4790K plus Mainboard(both used).

So this is my rig right now:

Processor:    4790K

Mainboard:   GIgabyte Z97X-UD5H-BK

RAM:            16G(2x8G) 1333Mhz

GPU:            EVGA GTX970 sc

PSU:            be queit! Pure Power L7 (630W)

HDD:           1TB Seagate Barracuda

SSD:           none :c

 

 

My problem:

Since I rebuilt my Computer with the 4790K and Mainboard (instead of the FX8350) and installed Win7 Ultimate it just turns off(no bluescreen or shutdownscreen just BANG-off) and then immediately restarts, asks if I want to start in safe mode and then just runs as usual... until it crashes again.

I've tried to cause this crashing several times but I can't find any pattern in it:

Situations it crashed in:

• while trying to upgrade to win10(yeah hate me for this) using the media creation tool          //like three times in a row... then worked until it stopped while searching for updates
• while Installing TeamSpeak and the most recent graphics-driver at the same time               //once... never tried again(worked seperated)
• while Installing .NET Framework during first start of a Steam-game(Arma 3)                       //twice... then worked
• while Installing .NET Framework manually                                                                            //once... then worked
• while starting Arma                                                                                                                //once... then worked
• when I tabbed bach into Arma after opening TeamSpeak and Chrome                                //once... never tried again
• when I opened Chrome while Installing 3DMark                                                                   //once... never tried again
• while starting the first benchmark of Fire Strike                                                                    //once... then worked until loading the combined one after the physics

We need more info dude. Did you keep the windows installation? Did you completely remove the old drivers and install the new ones if so?

Sounds like a motherboard problem to me. Is it overclocked?

Nope... at least not yet

Are you completely sure? It might still have over clocking settings from the previous owner. Reset the CMOS and run a stress test.

How ?

[deadaccount69]

Usually in the BIOS there's an option on the save page to "restore optimised defaults". Failing that, there a little jumper on the motherboard. Move the jumper while the system is off and mash the power button a few times. Then move it back and it should be reset.

[nysnys123]

Okay... I'll try.

[nysnys123]

well... now everything is set to Auto. I'll run Fire Strike to stress it a bit.

Did the bench: http://www.3dmark.com/3dm/15475399

But there was another crash, between launching 3DMark and starting the benchmark.

Remove one ram module, repeat test. If it crashes, put it back and remove the other ram module.

[nysnys123]

Tried every combination...

 

slot1         Module1

slot3         empty

slot2         Module2

slot4         empty

 

 

slot1         Module1

slot3         empty

slot2         empty

slot4         empty

 

 

slot1         Module2

slot3         empty

slot2         empty

slot4         empty

 

 

slot1         empty

slot3         empty

slot2         Module2

slot4         empty

 

 

slot1         empty

slot3         empty

slot2         Module1

slot4         empty

 

 

none worked without crashing

Reseat the CPU.

Reseat the CPU.

 

EDIT: And while you're in there, check that the socket isn't damaged and that no pins are bent.

what should that change ?

...

can't do that(at least today) because i had to cabletie-mount the cooler onto the CPU(temps are fine) and I haven't got any ties left so I wouldn't be able to re-mount it.

I had to tie it down because it's a 775 cooler and it won't fit.

[nysnys123]

Okay... so today I tested another power supply                                                                  //system crashed again but after playing arma for like an hour or so

 

now there are only three parts left which I didn't test yet:

          a- the GPU

          b- the processor

          c- the Mainboard

 

EDIT: tried without the GPU... only Intel HD graphics.... aaaaand, you guessed it: CRASH!
