Hi all,

I purchased the below this week.

Team Group Dark T-Force 16GB (2x8GB) DDR4 PC4-25600C16 3200MHz Dual Channel Kit
MSI B450 TOMAHAWK (Socket AM4) DDR4 ATX Motherboard
AMD Ryzen 5 Six Core 2600X 4.20GHz (Socket AM4) Processor
CoolerMaster MasterBox MB500 Midi Tower Case - Black
Gigabyte Radeon RX VEGA 64 WindForce OC 8GB HBM2 PCI-Express Graphics Card
Bitfenix Formula Series 750W 80 Plus Gold Power Supply
Seagate 2TB BarraCuda 7200RPM 256MB Cache Internal Hard Drive (ST2000DM008)
Gigabyte UD Pro 512GB SSD 2.5" SATA 6Gbps Toshiba 3D NAND Solid State Drive

I had fun building it, today has been my first time playing games for a long duration. For some reason the computer shuts down randomly and I'm unable to restart it with the power button. If I remove the power cable for 5 mins, then plug it in the unit powers back on.

One thing I have noticed is I've not seen the graphics card fans start up in when playing games.

Other than that I'm at a loss as to what the issue is. The computer shutdown about 20 mins a go, and I've switched it back on. Is there any diagnosis tool I can use to see if windows logged a fault?

Thanks
 
It sounds like the graphics card could be faulty, and overheating, then has to cool before the computer will boot again.

does the power button allow the machine to post, and then stop, or just not cycle on at all? no LED's? or anything?

The power cable/s plugged in correctly to the graphics card from the PSU?

Event Viewer would be the thing to look at for faults, though it'll possibly just say power kernel system failure or some such for a hard system shutdown like that.
 
Its completely shut down, the power button does not work. I remove the power cable then the system will boot again.

Yes, the power cable is connected correctly.

I could try putting in my old GTX 980 to see if the fault happens again.

Event viewer under critical indicates Kernel-power error.

I ran a GPU stress test and the fans did kick in, I'm thinking its the power supply?

The system shutdown on the second stress
 
I think it’s definitely the graphics card. My GTX980 has been on a graphics card a GPU stress test for an hour and a half, the system has not crashed once.

The Radeon lasted less than 10 mins away on stress, shame lovely card when it works.

Seems likely, though as far as I know it's the PSU that decides if it's going to be fussy about turning on again. Might be worth putting the Vega64 back in one more time and also keeping an eye on temps in MSI Afterburner.

Also according to this that card requires two 8 pin connectors to power it. I'm vaguely aware of advice on this forum that if both power connectors are split off from something else/share the same cable from the PSU or something, then bad things happen to Radeon Vegas.
 
If it doesn't shape up trying what Vexr said (using two distinct power cables if you aren't already, rather than two connectors on the same cable) best option is reject product for full refund within 14 days. They say the Sapphire Nitro+ is the best Vega64. Comes with GPU anti-sag bracket too.

Good thing you had another GPU to test, at least.

How did you connect power cables to graphics card?
For any overclocked Vega 64 you definitely need to use separate cables from PSU for both connectors.
Otherwise its current draw spikes will very likely trip current limiters of those artificially current limited wire groups. ("multiple rails" in marketing BS)
And clearing triggered PSU's protections usually needs power cycling it.

what we meant is: have you used 2 separate PCIE cables to connect to the GPU?
some PSUs have PCIE cables that have 2 end connectors.
for vega GPUs we recommend using 2 separate cables, one to each power socket - rather than 1 cable to connect both power sockets on the GPU
 
Vega 64 Windforce shouldn't crash , specially under stock speed.

Also fans should be kicking in whilst playing !

Formula should have two separate PCIe cables and both should be used

Nirto + Does have the biggest heatsink but PCB is half the design with half the number of phase's , hence its design to handle the extra heat.

Is aorus engine installed to control fan profile ?
 
When my Titan XM arrived the fans failed pretty much immediately. Infant mortality is still a thing in the PC world.
 
What you should do is fire up one of the gaming benchmarks - Futuremark, Heaven, whatever - and while that's running look at the GPU. See if the fans are moving. If they're not, contact OCUK customer service - assuming you bought it here - and they'll take good care of you.

Windforce has 6 phases doubled. Nitro+ has 7 phases doubled. With the better cooler, it also keeps the actual chip cooler.

Gigabyte have been naughty claiming more phases without stating half are doublers. As you probably know, there was similar trouble on the motherboard front.
 
Its a bit odd I installed the Aorus engine with the nvida card in and I have the options to view the fan settings.

I've done a full nvidia software removal, shutdown took the nvidia card out, put the new Radeon in, turned on the PC the GPU fans where constantly on. Install the Radeon drivers, rebooted windows, the fans started for a few seconds then stopped when windows started. Opened the Aorus engine I have no fan options.

Fans have not moved since typing this.

About to do the stress test again, don't have much hope.
 
That the fans did start is a good sign. Try removing the Aorus engine software. Also check for other legacy fan control software.
