What version of SolidWorks are you running on your machine there?
Have you updated your Graphics card driver or at least ensured you are using the certified drivers found here: Graphics Card Drivers | SOLIDWORKS
When you are accessing files are you doing so from your local machine? or are they located on a Network location?
Are you able to repeat the hang is there something in particular you are doing?
SW 2015 SP03,
I've updated their new driver, when switch to 1st intel integrated Graphic card, SW Rx certified drivers fail, No Realview, But No Hang;
If Switch to 2nd AMD Firepro, the certified drivers right, But SW hang.
working files in Local disc;
it's happen by accident,
the same issue on same PC to be found in this Forum, So far it also still haven't been resolved; unfortunately, I haven't find this post before I order from HP.
there are not any feedback from HP side to me,
SO Sad !!!!
Today, I try to use AMD Graphic BENCHMARK Test my 2nd graphic card, the test been terminated, running hang. So is it confirm the graphic card fail?
Have you run the SOLIDWORKS Rx > Diagnostics tool?
Are you using the HP specific 14.301.1002.1006 driver?
It could be the graphics card, but it could also be the CPU overheating and lowering the voltage to protect itself.
Try running some temperature monitoring apps like...
I've tried SW Rx ago when 1st problem was happen.
During running SW, the graphic card sometime show AMD Firepro, the test passed; but sometime show Intel integrated HD, the test Error.
i also run the Real Temp to monitor CPU temperature, no strange issue.
