Slows dramatically and freezes over time

[Bonster]

I am using an Inspiron 3000, Intel Core 17 processor. This is a new issue for me, I believe it started with the last major Windows 10 update. When I open SH3D, it runs fine for a little while, then begins slowing, with more graphical glitches (furniture appearing as white boxes rather than rendering), then freezes entirely. Sometimes it locks up my whole computer and I have to force a restart. I've updated my drivers, but it hasn't made a difference. Any suggestions?

Did you try to run Sweet Home 3D 64 bit (run installer again and select 64 bit architecture in the screen which lets you choose the installation folder)?

Tried it now - I'll let you know if it works! Thank you!
