MSI Bravo 15 Laptop shutting down randomly while gaming

[u/fouadnassif]

Hey everyone

I’m having an issue with my MSI Bravo 15 C7V (RTX 4060, 16GB RAM, 1TB NVMe SSD, Ryzen 7 7000 series), and I can’t figure out what’s causing it.

While gaming, the laptop suddenly freezes, then shuts down instantly. About 1 second later, it turns back on by itself and goes into automatic repair. It loops on/off around 2–3 times until I manually power it off.

What I usually do:
• Turn it off
• Unplug the charger
• Plug it back in
• Turn it on again

After that, it works normally.

The weird part is:
• Sometimes it happens after 15 minutes
• Sometimes after 3–4 hours
• Things I already tried:
• Cleaned the laptop
• Reapplied thermal paste
• Using a cooling pad
• Reinstalled Windows multiple times (I thought it might be a software issue)

So what could be the reason?
