so everything was fine, had the computer off-line for a while whilst decorating the room, put it back on again 2 days ago and everything was fine.
Updated yesterday and it looked weird but started working, this morning, keeps crashing on boot (not the PC, roon does).
Never really had any problems before, so not sure what to do.
Tried the usual turning it on and off again, uninstalling, reinstalling. Still not working
Can anyone help?
I have moved your post from #uncategorized to #support.
If you had posted in #support right away, you would have been presented with a template asking questions. I’m copying it here, please provide the information so that we know what we are working with:
<!-- Include your operating system and machine info (Model, CPU, RAM) →
<!-- Your network gear (model of routers/switches), if on WiFi/Ethernet, and if you are using a VPN–>
<!-- Specify what devices you’re using and their connection types, like USB/HDMI/Chromecast, etc.) →
<!–Tell us how large your music library is, eg. “30,000 tracks” →
my apologies, never had any problems before so don’t come on here very often.
custom windows machine, running Windows 10, I 7 CPU, 16 GB RAM,
Wi-Fi attached library via Auralic Aries G1 player USB connection
13,366 tracks in the library
No worries, it’s just so that helpers have an idea. Sometimes it turns out that it’s 2 million tracks in the library or a 10 year old CPU with 4 gigs RAM, so it’s good to get this out of the way 
Nothing obviously problematic here of course …
It is not clear what was updated? Windows or Roon Core?
it was Roon Core
And just to be clear for support, are you running Roon or RoonServer on the PC? If it is Roon, then what might be crashing is the video component.
One thing you might try is updating your PC’s graphics drivers. Roon official support is Monday-Friday, everyone responding so far are friendly fellow users trying to help out.
using Roon
yeah those GPU drivers are all up-to-date, thanks
