Thread started by described a system hang after a recent hardware change. Both and raised sensible possibilities (motherboard damage and cooling). The most reliable approach is methodical isolation: narrow the cause by changing one variable at a time.

Begin with a minimal hardware boot: disconnect all nonessential drives and peripherals, fit only one stick of RAM (try each slot), and use the motherboard video or a known-good card. If the system becomes stable, add components back one at a time until the hang returns; the last-added item is the likely culprit. Check the power supply next — unstable rails or weak amps often show as intermittent hangs. Swap in a known-good PSU or use a PSU tester/multimeter to confirm voltages.

On the software side, boot into safe mode or a clean environment (a live USB) to rule out driver or OS-level causes. Inspect Event Viewer or system logs for Kernel-Power, driver, or disk errors that match the hang times. Remove and reinstall display drivers if the problem appears tied to graphics. Reset BIOS/UEFI to defaults and, if available, update to a recent vendor release.

Run memory diagnostics (memtest) and storage SMART tests; both RAM and failing disks can produce hangs that look like hardware faults. Check thermal behavior from BIOS or monitoring tools and verify fan headers, heatsink seating, and thermal paste if temperatures are abnormal. Use anti-static precautions when reseating parts.

If the fault persists after isolation, bench-test suspicious parts in another machine or take the system to a shop for component-level testing (motherboard trace/VRM, PSU load testing). Avoid powering or continuing to use hardware that shows visible damage; professional repair or replacement is safer.

Hi,

Did you check with replacing the motherboard, it's possible that the motherboard also got damaged in the process

good luck

your cpu might be overheating so check that it has enough cooling by checking your internal fans
