I have recently started using Blender 2.8 after using 2.79 for some time. I used to render everything alright, but now, I changed from my old laptop to the new PC.

So, I am using the scene with the materials I have bought online, creating there an interior scene, but in many cases (not always though) Eevee and cycles are either stuck for longer than they should (comparing to the old setup) or it crushes to the point that my screen simply turns off (screen is connected to the graphics card).

That is all just weird because the specifications are very obviously way better than I used to have, but not it barely works.

My former laptop:

ASUS UX303U

Intel® Core™ i7 6500U Processor

DDR3L 1600 MHz SDRAM, OnBoard Memory 4 GB, DIMM Up to 12 G

Graphics card: Nvidia 940M

My new PC:

Self-assembled

AMD Ryzen 7 2700x eight-core

DDR4 2666MHz HyperX 16 gb (2x8gb)

Radeon RX580 (2 of them working on the AMD crossfire).

So, if you have any ideas about why is this happening - let me know. Thanksenter image description here

You should probably reinstall Blender. The reason your screen goes black is probably that when Blender "crashes" he starts to pull huge amounts of ram so keep your task manager open and before he eats more than let's say 80% you force close it. If the problem keeps happening I can't help you much. It's probably some system error.

  • $\begingroup$ Thank you for your answer! I did that, also updated Blender, also it doesn't seem to have that many problems when I render, but rather when I try to change viewport shading to rendered. I starts to eat way too many resources and does not really give any result. I assume it might be because the scene could have a lot of materials, but I am not sure. Will try to do the same on the clean file. $\endgroup$

In properties/dimensions/resolution you can change the resolution from 100 to 0, maybe setting it to 10 % and look if it is ably to render something with that setting. if it can, your render may be just too heavy... and you should consider rendering your scene in parts ... I think in the newest version they are called passes ... using blenders way of layering and then compositing the different layers together.
