Hi all, I seem to be having some issues with system stability when playing battlefield 1 multiplayer. I don't think this is exclusively down to battlefield itself because I recall experiencing similar issues when I used to game, approx 12 months ago. My system is detailed in my sig. I have a very small modest overclock on my GPU +75 core +100 mV and 150 % power limit in afterburner. I've tested this in valley benchmark and it's stable at +100 core but I dropped it down to be safe. No mem oc possible. My CPU is overclocked to 4.6 Ghz (46 x 100) on 1.39 V. Note: running Windows 10. The instability occurs once every 30-60 mins whilst playing multiplayer (currently on high settings). Hasn't happened yet on SP. The screen is unresponsive, system is locked and the sound freaks out - a very short repeating noise). If I review the event log I find Critical Kernal Power error - event ID 41, task category 63. I've also been having the following intermittent hard drive messages "The driver has detected that device \Device\Harddisk1\DR1 has predicted that it will fail. Immediately back up your data and replace your hard disk drive. A failure may be imminent." I'm running my SSD as my primary and a mechanical as storage. I also get BSODs displaying the message ... system service exception (ks.sys) ... one immediately prior to updating this thread when I tried to update origin. Furthermore, sporadically I get electrical noises coming from my PSU. It doesn't happen that frequently. So .... does the fault potentially live with the HD/PSU or the GPU or another source? Any help or troubleshooting welcome! As an aside, I hope my brother will bring his PSU and GPU this weekend to isolate either of these two components under test. Thanks!
