Treat this as a diagnosis, not a shopping trip. Below is an ordered, South African gaming checklist for the symptom in the heading, written so each step is something you can verify yourself before booking a repair or buying a replacement.
Quick Answer
Treat this as a diagnosis, not a shopping trip. This usually comes down to the storage drive, an unstable EXPO profile or background load rather than a faulty AM5 motherboard. Run a fixed 20-minute test after each change and keep the one that holds at a steady frame rate or a stable temperature under 85C.
Drive health and thermals
Move the boot drive off a shared lane if a second M.2 device steals bandwidth from the GPU slot. Watch disk activity during the freeze; a Gen 5 NVMe drive at 70C or more will thermal-throttle and cause micro-stutters.
RAM and EXPO checks
Re-test with the EXPO or XMP profile off; an unstable 6000MT/s kit can throw stutters and crashes that look like a board fault. Run a short MemTest86 pass overnight to rule the 32GB kit in or out before blaming anything else.
Heat and airflow checks
Reseat the cooler and apply a fresh pea of paste if temps spiked after a recent strip-down. Reseat the cooler and apply a fresh pea of paste if temps spiked after a recent strip-down.
FAQ
How long should each test run?
Use a fixed 20-minute load that reliably triggers the fault. A shorter burst can hide a thermal or memory problem that only appears once the system is fully warmed up at 80C or higher.
Can a single bad cable cause this?
Yes. A half-seated 8-pin or a marginal DisplayPort cable can trigger shutdowns, flicker or stutter that look exactly like a dying component, so reseat and swap cables before spending anything.
Will a BIOS update fix this on its own?
Sometimes, but flash only the latest stable release and reset to defaults afterwards. A fresh BIOS plus a clean chipset driver clears a surprising share of post-update stability faults.
Replace only what the evidence shows
If the checks isolate the fault, compare current AM5 motherboards on Evetech and upgrade the one part that proved unreliable.
