Thanks in advance for any help

Best regards,

The generic nature of the 0x124 (Arg1=0) stop code means we would have to take
the trail & error approach.

Do you have any spear parts (or another PC) to test with, mainly a PSU?
The usual suspect of this kind of BCCode is the CPU but it's often not the the case which is why we need
to test other components to rule them out as the cause.
How old are your components?


What is the make an model of you PSU?
Fill out this form and post back the result:

• Power Supply Calculator

Good practice, open up the case and re-seat all types of connection.

• SATA Cables (HDD/SSD/ODD).
• SATA-Power.
• Motherboard 24-pin.
• Motherboard 4/8-pin (CPU).
• Re-seat the RAM.
• Re-seat the GPU.

Make sure that every slot / cable head is free of dust or other obstruction.
Make sure that every connection is seating properly and firmly in-place.

Also have a look at the motherboard and the GPU, search for any "bad caps", bulky, leaking bloated capacitors.

i.e

• Download Speccy and post a Screenshot of the summary window, one at idle and another while putting load on the PC using Prime95 for the CPU side and Furmark for the GPU.

Reset the BIOS back to default in case you're unaware that your CPU is overclocked:

• CLR CMOS
