Note:
1. Recently installed new NZXT PSU 850W 2 days ago
2. Recently installed 240 mm AIO cooler for processor
3. Did stress test on processor using OCCT, no issue. Processor max temp was around 59-61C
4. Did stress test on graphics card using OCCT, no issue. Graphics card max temp was 70C.
5. PC was running fine for hours each day, for past 2 days
6. Did some gaming past 2 days and monitored GPU and CPU temps, all fine. GPU temp at 75C; CPU temp at around 56-58C.
7. The only part i have not bothered is the processor. I don’t dare to unscrew the cooler and looked into processor as I don’t trust my own hand. Processor requires more delicate handling.
8. The Samsung NVMe is the boot drive.
No help at all. Where else should I check?
PC refuses to turn on, Very random situation
