PC randomly restarts when lightly loaded (doesn't even need to boot into OS, sometimes restarts while in UEFI). Give it something to do and boom, no problem. Currently running Prime95 on one core so it doesn't restart.
Looks like my PC just doesn't tolerate boredom. Or likes being a radiator.
- CPU: Ryzen 5 1600
- MOBO: Gigabyte AB350M-DS3H
- GPU: Asus GTX 1050Ti
- RAM: Goodram IRDM 2x8GB 2400MHz
All above are factory new. PSU and drives moved from old computer.
- PSU: Chieftec CTG-450-80P
- Main drive: OCZ ARC100 240GB
- OS: Win 10 Pro
- Other drives: WD Blue 500GB SSD, two Seagate 500GB HDDs
The things I've tried
- Checked temperatures when idle and under heavy load - perfectly normal
- Checked power plan settings, set all of them manually to favor high performance
- Ran Memtest just in case - no errors
- Checked voltages on a multimeter (also during crashes) - perfectly stable and within desired ranges
- Disabled "Cool&Quiet" in BIOS (supposed to lower CPU voltage when idle to save energy and lower heat dissipation)
- Manually setting multiplier to standard frequency, and voltages to what they averaged to while stress testing with Prime95
- Stress tested with Prime95 and Furmark simultaneously to check for PSU-related issues, as well as general stability issues
All that to no avail, save for the "cool'n'quiet" thing - restarts are a little bit less common with it disabled. The issue, though less frequent, remains unresolved.
Though it doesn't look like a PSU-related issue, unfortunately I don't have another one handy to test it, save for some 200W old ones.
Same goes for pretty much every other component on board.
