Blender version 2.79 and older crashes on startup Recently Blender version 2.79 and older crashes upon startup in my Windows 10 64-bit computer, and after further inspection, apparently it has something to do with the Cycles renderer. Blender 2.80, strangely enough considering it's still in alpha state, works fine, until I activate the Cycles renderer method and crashes itself too.

What I mean by crashing is the application freezes forever, making Blender prior to version 2.8 unusable in my computer. I tried fresh install from official installer, nightly build, updating the GPU driver, and nothing changed after following the troubleshoot procedure. When Blender freezes, the Task Manager shows Blender is using 25% of CPU usage and doesn't change far from that number.

Using --debug-all command line argument shows the program freezes after CLEW Initialization Succeed.

I can't continue with Blender 2.8 since I'm relying on an addon that doesn't work on 2.8. So, how do I solve this problem?


OS: Windows 10 Home 64-bit
CPU: Intel Core i5-6200U @ 2.4GHz
GPU: AMD Radeon R5 M330, using latest Catalyst driver
Reinstalling the Windows (build 10586, with proper drivers installed) finally solves the problem and Blender runs fine, even the Cycle renderer works fine too. 

I had no idea why that problem persists before reinstalling, because previously, I already tried troubleshooting by:


using --factory-setup argument
deleting Blender's AppData stuff
switching GPU driver versions back and forth
trying other versions of Blender (including nightly builds)
reinstalling Blender


...and aforementioned steps doesn't solve the problem for me.
