So, my stock speed CPU is stable/ non-defective ?įirst solution is to ensure you have the latest bios update for your motherboard. I can surf on the web, watch Youtube videos etc. Utilization is nearly %100 for all 12 threads. File size of the result video is 6 gigabytes. I run HWinfo at last 30 minutes of OCCT test. I run OCCT stress test with default settings for 1 hour -> NO ERROR. I converted 885 mp3 files in 15 minutes to 320 kbps and again NO PROBLEM. I run Cinebench R15 for 10 times with this method: When rendering ends i run it again immediately before the CPU gets cold. Today i tested my CPU with these methods:ĪIDA64 stress test, 30 minutes -> NO CRASH.

So i don't know if my CPU or GPU or both are defective. I tried different methods but couldn't solve the problem unfortunately.

(According to manual, it shows CPU faulty or no CPU found.) It shows an error i think.īut also Ez debug led (CPU) of motherboard is indicating. The interesting thing is, when PC freezed/ crashed, RGB LEDs of my graphics card is lighting red to white colours. My AMD built PC (RX480 GPU & Ryzen 5 1600) is crashing at GTA IV, Metro Last Light, Metro 2033, Crysis1, Crysis Warhead, Dirt3: Complete Edition.
