By the way.... I don't know your memory at all.

 

M392B1K70CM0-CH9

 

Is there HP memory that has that code?

HP Recommended

Sorry for the late reply.. Sticking to a single processor would be my last resort if there is no other option.. I think we drifted from the main problem.. Is it possible to upload a video?

HP Recommended

It's samsung not hp.. What does the memory has to do with the problem at hand?!

Well.. A mosfet turned out to be the problem causing the shortage.. Now another problem surfaced😕 it powers on normally with riser connected.. Fans spins and all but no data.. It still functions properly with the riser removed🙄

it's rare for only one component to fail when things like a  mosfet craps out, 

 

When MOSFETS fail they often go short-circuit drain-to-gate. This can put the drain voltage back onto the gate where of course it feeds (via the gate resistors) into the drive circuitry, possibly blowing that section. It will also get to any other paralleled MosFet gates, blowing them also.
So, if the MosFets are deceased, check the drivers feeding the MosFets as well

 

Connect the 'Source' of the MosFet to the meter's negative (-) lead.

1) Hold the MosFet by the case or the tab but don't touch the metal parts of the test probes with any of the other MosFet's terminals until needed.

2) First, touch the meter positive lead onto the MosFet's 'Gate'.

3) Now move the positive probe to the 'Drain'. You should get a 'low' reading. The MosFet's internal capacitance on the gate has now been charged up by the meter and the device is 'turned-on'.

4) With the meter positive still connected to the drain, touch a finger between source and gate (and drain if you like, it does not matter at this stage). The gate will be discharged through your finger and the meter reading should go high, indicating a non-conductive device.

Such a simple test is not 100% -- but is useful and usually adequate.
