Morning all.
For the pass couple of days my computer has been restarting randomly.
I haven't noticed it restarting when it is idle or Web browsing.
All drivers are up to date but still happens and usually when gaming.
It's a fresh build with some new and old parts
Ryzen 5600x
Gigabtye b450
Vega 56
16gb ram
500gb nvme
1tb ssd
3tb hdd
Cpu temp is never over 55c and gpu is max 70c so I am pretty sure it's not a over heating problem.
The psu is a evga super nova g2 750w brought in Jan 2015. Its been brilliant but getting long in the tooth.
Do you think it is rhe psu ?
 
Have you enabled XMP?

How new is the BIOS?

Which parts in the build are 'proven'?

You could try downclocking/power limiting the Vega.
 
Have you enabled XMP? Yes I have.

How new is the BIOS? I updated the bios to the latest one about 5 months ago. To put the 5600x in.

Which parts in the build are 'proven'? Vega 56 is well as you can imagine been proven. Since getting it years ago no issues. I have not abused it in any way (mining etc)
Ram I had with my 2600x. No issues.
Mother board is less than a year and again had n issues.
Psu well had since Jan 2015.

I may try mem test later to see if it is the ram.
 
How often is randomly?

Is it the same game?

My used to do that in PUBG only, and it was so infrequent (literally 4-5 times a year) I didn't bother trying to diagnose.

I'm still using that very same PSU today and it's fine.

Try running ungine heaven or some similar looping bench and see if it does it.

Point I'm trying to make is itight be the game has some random ****** bit of software that causes your pc to restart.
 
Did a ram test last night all ok..
I left ungine heaven on last night for 3 hours.. no restarts.

Well the random restarts happened on different games but not always. And only the past week. Hasn't happened everyday..
The games are World War z, warhammer verminetide 2, battlefield v for example.. oh and maybe start craft 2

Is the 'new' CPU actually new, or used?

Based on what you've said, conventional troubleshooting would suggest that the CPU is the problem, but, it isn't uncommon that newer CPUs on older motherboards can have stability problems. Do you run PBO? You might want to try raising the stock voltages a little bit, though that usually fixes idle reboots, not gaming reboots.

The cpu isn't new. It's actually from a rl friend who hasn't had those problems and I trust him.
I did have ryzen master installed but I don't think I had any optimisations or pbo.. but I reset any thing I had and uninstalled it so now its running as stock with no tweaks.
Will try the games again tonight and see what happens.
 
Well I was only having the reboot in bf v after the things above. I turned off xmp and played bf for 2 hours with no reboots. Strange. I did get slightly different speed ram.. one at 3200mhz and 1 slightly less. I can only guess that could have been the case. Will continue trying and see.
Disabling xmp. Would I lose lots of performance?

10%;+ depending on game .


You may just need to add a bit more voltage to get the memory stable .
 
Well turned xmp off and increased voltage on ram.. no pbo on. Everything is stock about from ram voltage.
It's been fine for a while. Bf v, vermintide 2 not crashing etc until tonight.
Was on vermintide 2 for maybe 30 or 40 minutes and pc restarted again. Played bf v for an hour tonight before hand as well was eorkd of warships.
Increase ram to 1.3v?
 
Battlefield V is rubbish. The only game I ever had issues with previous 8Pack DDR4 Samsung B-die. Even with higher voltage. Everything else I was able to run the 3200 kit at 3600 and same clocks and voltage. Some games are bad. Simple as that. At the moment, had to reinstall CoD Cold War 3 times to stop it crashing. Oldish game, as I have way more games than time to play, and spend much of that time swapping parts :D
