I tried overclocking my CPU, i5 8600k, using Asus' EZ tuner. It made some changes to my CPU settings. After that, I ran Aida64 for about 40 minutes and my temperature never went higher than 65. I thought I got a stable OC so I played Battlefield 1 at Ultra and 1440p to see if it really was stable. After 15 minutes of gameplay, my computer froze so I hit the reset button on my computer case. After booting up to the desktop, I would get an WHEA Uncorrectable blue screen error. I tried resetting my bios settings to remove the overclock but I would still get the error. Increasing the CPU's core voltage to 1.2 seemed to help but it would still give me the error but after around 30 minutes of use. I tried monitoring my CPU's temp and it never went higher than 50 before it crashed. Does this sound like a hardware problem? Could it be my PSU or CPU? My PSU has 650w and is bronze. I even tried re-installing Windows 10. I've never had this problem before.
