cpu CPU dead?

[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.

After one Week of testing and searching Internet forums I finally (kinda) found the problem:

When I stress the FPU or Cache via AIDA64 this crash occurs. And also it does not occur with my Celeron in the System.

 

So my Question: Is the processor broken? Or is it the mainboard? Or something else?

 

Parts I already excluded by removing or swapping them with spare parts:

 

Powersupply

Graphics-card

RAM

 

 

Thanks!

Almost 100% sure its your power supply! CPUs dont really break like that, either work or dont, very low chance of it being CPU, also try seating just one stick of RAM?

Much more likely to be your MoBo than your proccesor (assuming your testing already eliminated the PSU as the source of the problem).

If the PSU has not been eliminated I would test that first as this is almost certainly where your problems stem from.

Well thanks so far but I've tried like every possible combination of RAM-sticks, with another CPU in it, without a graphics-card in it, with another PSU in it... and the only things I couldn't or just didn't try to swap are the MoBo and the HDD but every one of the tested combinations did crash aswell excep the one with another CPU, that worked just fine. Even when stress-testing it in AIDA64.

That means the only things the system had in it every single time it crashed are CPU(4790K), MoBo and HDD.

More than likely the MoBo then.

Even though It worked fine with a different CPU in there?

It's still crashing with a different PSU powering the system. Already tested that.

Did you check your bios settings? try to reset it back to the default settings and give it a try.

Different demands at different areas so different results.

Not saying it can't be your processor but it is much more likely to be your MoBo .

 

Take it you can't get a known good copy of your 4790K chip and try that?

 

Found this .  Anygood?
