New build, hard freeze after left idle
I've been having problems on a recently built machine when if left idle, the PC wont respond from anything.
The screen is black and the keyboard doesn't respond either. Upon forcing a restart, the machine doesn't boot up multiple times until it finally goes through to POST then Windows (But this could be another problem?).
This has happened since I built the PC (around the end of March) after leaving it on for at least 6hrs, usually after rendering but sometimes just left idle. The rendering has finished successfully every time and I have had no freezes during any other rendering whatsoever.
It is more likely that it is having problems during idle then when under load.
The first thing I did was turn sleep off then I disabled the automatic power off for network adapters (under Device Manager) and such as I saw this fixed the problem for some but this hasn't worked.
I have also added to the registry 'System unattended sleep timeout' and set it to 0.
Going into Sleep mode and back causes no problems.
The system has passed Prime95 on stock settings, chkdsk, sfc, memtest, unigine and cinebench.
Temps are within good ranges. Drivers are all updated.
I also tried increased the load-line calibration in BIOS as I thought maybe the CPU wasn't receiving enough power during idle.
it's a work machine mainly used for CPU and some GPU render and AI stuff.
Specs are as follows:
CPU: Threadripper 2990wx
MB: x399 Taichi
PSU: 850w Thermaltake
STORAGE: 500GB + 1000GB SSD
OS: Windows 10
Any help is appreciated!
