I ran the ram test a couple of days ago.... no problems reported. That it was the power supply was
the first thing I thought of but then I wondered why it would only happen when running darktable.
How would I check that? What are the proper levels?
At boot, you have to press some kind of button to get into your BIOS or EFI menu. Depending on
computer brand it might be ESC, F1, F2, F12 or something like that. If you're lucky it'll tell you
what button to press when you boot your computer, and it should be listed in your motherboard
manual. Then poke around in the menu until you find the right "status" area or similar where it
lists the power supply voltages. In general, it'll list what voltage it expects, and then the
actual voltage it's getting, something like:
12V: 12.02
5V: 4.96
3.3V: 3.24
You just have to compare, and make sure they're not too far off. I just did a google and came up
with this:

Voltage Rail Tolerance Minimum Voltage Maximum Voltage
+3.3VDC ± 5% +3.135 VDC +3.465 VDC
+5VDC ± 5% +4.750 VDC +5.250 VDC
+5VSB ± 5% +4.750 VDC +5.250 VDC
-5VDC (if used) ± 10% -4.500 VDC -5.500 VDC
+12VDC ± 5% +11.400 VDC +12.600 VDC
-12VDC ± 10% -10.800 VDC -13.200 VDC

Hello ladies and gentleman. Well darktable seems to be causing my
system to reboot and on a
rare occasion to crash. I think it is the video card (it only reboots
when I am running
darktable and
If you suspect the video card, try disabling OpenCL processing:
* Darktable Preferences (cog icon, top right of lighttable)
* core options tab -> activate OpenCL support (untick this)
But sadly it could be caused by a myriad of things, like bad RAM, bad
cooling, bad power supply,
bad caps on the motherboard, etc. etc. You could do a RAM test using a
live CD, and check the
BIOS/UEFI for voltage levels coming from your power supply. The other
things are harder to
narrow down.
