Question Computer randomly reboots ?

[gothardware]

Bought a new pc from techfast.


Specs:
https://www.ozbargain.com.au/node/666615

• Intel Core i5 10400F processor
• RTX 3070 Ti 8GB LHR graphics
• Gigabyte B560M DS3H motherboard
• 16GB 3200MHz RAM
• 500GB NVMe m.2 SSD
• 750W 80 Plus Gold PSU
• MAG Forge 100R Case

Also before crashing in event viewer it gives error with Event ID 56, ACPI 2 source from Application Popup. Before crashing from source of Kernel-Power.

When left idle just downloading things or when using it normally, it will randomly reboot. No BSOD, just a turn off and reboot. Turned off automatic restart, will restart regardless.


I've made it so when powered/not powered it should not go to sleep.
I've tried enabling power loading in BIOS.
Tried reinstalling USB drivers as I had issues with it disconnecting and reconnecting too.


How to stop it from restarting randomly when idle and downloading things?

E: It just randomly restarted when extracting files from a zip, so it's not just when idle. But then extracting files upon reboot, it works fine.

E2: I tried the memtest 86, but it reboots during that test too. Not sure what that means. Windows memory diagnostic came out fine though.

Also look in Reliability History for error codes,warnings, etc.. Reliability History is much more user friendly and presents a time line formation that can be very helpful.

Check Update History for any problem updates.

Perhaps some corrupted files:

Run "sfc /scannow" and "dism"

DISM Overview | Microsoft Docs

Not familiar with techfast but if that is a local business/store take the new pc back for service under warranty.

My thought is that there may simply be a loose connection, card, RAM, possibly causing the problem. Something that you can probably look for and fix.

However, depending on the warranty, opening the case may void the warranty.

Whats the brand and model of this "750watts 80 plus gold" PSU?

According to someone on that page, it's an MSI MPG A750GF 750W 80 Plus Gold unit which if true, isn't bad.
