My PC is randomly rebooting, I honeslty have no idea why this is happening, it's not because of my CPU temperature thats for sure. it doesn't reboot very often, I think 4 times a week or something? (like I said it's really random).

Here are my PC specs:

PSU: Cooler Master B500 V.2

Processor: AMD A10-7850K Radeon R7, 12 Compute Cores 4C+8G

Video Card: NVIDIA GeForce GTX 950

RAM: 8.0 GB

Operating System: Microsoft Windows 10 (build 10586), 64-bit

Thank you!

Short of having thousands of dollars worth of test equipment to do a proper ATX or Intel spec compliance test (Intel's Haswell PSU requirements are tougher to meet than than ATX 2.3x's), the simplest way is to swap it out with a known-good higher quality unit with sufficient rating to run your system.

Does it reboot while performing a task or gaming, or is it always idle? How old is that PSU? Have you looked at Event Viewer to see if there are any events associated with the reboots? Does it shut down/restart, or does it BSOD first then restart?

The rebooting is really random, sometimes during gaming and sometimes just browsing the web. My PSU is max 2 years old. (since i bought it)
I have not looked at Event Viewer (neither do i know what it is/how it works). It only just reboots, no BSOD.

Before you try anything else, may want to run memtest86 for a few hours in case your crashes might be caused by an intermittent RAM bit.

CoolerMaster is mostly known for poor quality PSUs. Their V and VS series are very good, the G, GX and Silent Pro are decent, the rest are usually passable at best. There isn't much data on the 'B' series, which usually means it is a generic heavily budget-oriented line. Two years is often considered a good run for those.
