Help! PC turning off when playing certain games

Ethan Rotherham · 14 Oct 2019 at 22:44

Recently built a pc with the following spec:

Motherboard- MSI B450 TOMAHAWK MAX
Case- Kolink Observatory Case
PSU- Bitfenix Whisper M Series 650W 80 Plus Gold Modular Power Supply
SSD- Samsung 500GB 860 EVO SSD
GPU- Sapphire Radeon RX VEGA 56 Pulse 8GB
HDD- WD 1TB Blue Internal Hard Drive
CPU-AMD Ryzen 5 3600 with the stock cooler
RAM- Corsair Vengeance RGB PRO 16GB

The computer turned off in planet coaster and dirt rally 2.0. It normally shuts down within 5-10 minutes. However, sometimes it may shut down after 20 minutes or so. The pc runs completely fine in CSGO.

Checked the PSU for malfunctioning fan and no sign of a problem.
Also monitored the temps while gaming and they are running at 55-70 degrees for the GPU and 70-80 for the CPU so dont think its temperature related.

GPU driver is updated and the Bios is currently on V30.

Any help would be appreciated, Thanks.

Temps seem fine for the specs you've listed, Have you overclocked the CPU? Have you got latest graphics drivers installed?

It’s my first build so haven’t even looked at overclocking anything to be honest. And yeah according to the AMD Radeon software I’ve got the latest driver installed.

My toaster could run CSGO

Have you tried a GPU benchmark/power virus to see if it does the same?

, no I haven’t tried a benchmark yet, I will try that tommorow

This haha, I was gonna post something like that about crappy csgo.

@OP - Try 1 stick of memory at a time, make sure no cables are touching any of the fans to cause a short and everything is built correctly and plugged in. Maybe build outside of the case and test if possible.

There's an image pic within the chat, or just use https://imgbb.com/ or another site and paste the link it gives.

The bottom front fan is close to that cable, try 1 stick of memory and see how it goes and then the other stick, and check the build properly mate.

Ethan Rotherham · 14 Oct 2019 at 23:22

Okay, thanks for your help. Will try it tommorow and keep you updated

One thing that you can try which has cured stability problems for others with Vega cards is to power the gpu from two seperate pci-e cables and not one cable with the daisy chained connectors as you have it at the moment.

Have you enabled a function in the bios called game boost? As this will enable an all core oc of 4.2ghz and sets a fixed vcore which if the cpu can't handle maybe causing the crashes as it adds load

MartinPrince · 17 Oct 2019 at 23:50

@Ethan Rotherham you are running an old bios, you need to update to the latest v33 bios and then I suspect you're crashing will go away.
There was a bug in the original bios in that when memory was set to XMP that the voltage did not change but was still at 1.2v, which in effect was undervolting the memory, which would cause random crashes.
