I RMA'd the motherboard, the retailer confirmed there was a fault but did not specify. I've been sent a replacement which seems to work perfectly with no issues Thank you all for all the help, It's very much appreciated

Interesting update: My mobo has four DIMM slots from left to right: DIMMA1, DIMMA2, DIMMB1, DIMMB2. - DIMMA1 is physically blocked by the stock AMD cooler and I don't think I have case space for a liquid cooler - either memory stick inserted into DIMMA2 boots the computer up fine, with no reboot issues at all - either memory stick inserted into either DIMMB1 or DIMMB2 now no longer boots the computer properly (hangs with black screen and with the MSI EZDebug light corresponding to "indicates DRAM is not detected or fail" permanently lit) - with either memory stick inserted into DIMMA2 AND the other memory stick inserted into either DIMMB1 or DIMMB2, same no boot issue as above. Note that yesterday, the PC still did most of the time boot up with two memory sticks in, but then just reboot under high load (this was my main issue) but now it doesn't seem to boot up at all with two sticks in. Given that I really cba to return and replace the mobo, and that I don't care about dual channel memory, can I just return my 2 x 8 GB sticks and get a 1 x 16 GB stick? Or is there something better I can do?

WTF! So, I removed one stick of RAM and everything seems to be fine. No reboots so far. I've tried it with XMP on and off. Does this mean I had faulty RAM, or maybe the BIOS didn't handle the dual channel well? Or the CPU didn't like it? Should I stick them both back in and run memtest86 then?

so... hooked up the brand new Seasonic Focus Plus Gold 550W and I'm still (!) having the same issue - seemingly identical. Whenever I go into an intense game or open loads of videos, the PC just reboots! I'm all out of ideas now, I've tried a bunch of different BIOS settings and even restored BIOS to default but nothing seems to stop the rebooting. Any further ideas?

I couldn't find a CPU overheat protection setting by name but I found some other things I thought might be related in the BIOS. I tried several different settings and all yielded in a reboot under high load (watching a few 1440p videos on youtube / playing Firewatch / playing Warzone). Your comments on PSU corroborate with others on separate forums. Thanks for the help! Indeed, I've tried monitoring temps realtime and pasted a HWInfo snippet of what happens right before a crash - seems they max out around 75-80 degrees C. I never even thought about PSUs degrading but makes total sense, thanks! Thanks, I had a go doing this but it sadly didn't seem to help. I've gone and bought a new Seasonic Focus Plus Gold 550W PSU which is arriving tomorrow - I'll have a go with this and see if it works!

I'll admit that I'm a bit lost and would thoroughly appreciate some guidance as to what I can do next. Context I've just built my 2nd ever PC (read: amateur) after deciding to upgrade most of the components of my first build 6 years ago. All parts (except 6 year old PSU) have been purchased <2 weeks ago with latest drivers/software installed and BIOS updated. Here's what I have: CPU: AMD Ryzen 5 3600 with stock cooler but using Artic Silver MX-4 paste DRAM: Corsair Vengeance RGB Pro, 2 x 8 GB, 3200 MHz GPU: Sapphire Pulse RX 580 PSU: Corsair CS 550M Mobo: MSI B450M Mortar Max 2 x Samsung 840 Evo 120 GB SSD (Dual booting between a fresh retail 64 bit Windows 10 installation and an up-to-date and stable Arch Linux installation, one on each SSD) 2 x Samsung 860 Evo 500 GB SSD Case: Cooler Master Q300L 3 x Corsair AF120 LED 120 mm case fans Built everything over a week ago. I booted up, I did not touch any settings in the BIOS related to overclocking. I even left XMP off as it was default (so the DRAM was at 2133 MHz instead of 3600). Everything seemed fine, installed windows, reinstalled Arch bootloader, booted into both several times did various admin things, everything still seemed fine. The issue Then, I tried gaming. Opened battle.net, started playing Call of Duty: Warzone, set the graphics to auto but increased a couple of settings a bit. Got into an online game just fine, getting ~75 fps. About 2 minutes into the game, the PC turns off and reboots (as if I'd pressed the reboot hardware button). I immediately check CPU temp using HWMonitor, it's at about 70 degrees C. I check Event Viewer, there's nothing in there for the <10 minutes previous to the surprise reboot, and no Errors for a while, but, timed after the reboot, there's an Error: "The previous system shutdown at <hh:mm:ss> on <dd/mm/yyyy> was unexpected." with Event ID: 6008. There's also a "Critical" entry with ID: 41 saying "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly." My troubleshooting I couldn't find other clues in Event Viewer. I tried again to play Warzone, this time watching my CPU/GPU/Case temps as I play. Roughly 2 minutes in, PC does the reboot, and at this time, CPU was about 75 deg, GPU was about 70 and case as about 40. CPU volts didn't go above about 1.4 V. Fans all seemed to be working fine and CPU fan had hit ~2000 RPM. Since then, I've tried a number of experiments: Turning on and off XMP, and trying various DRAM clock speeds Updating BIOS to latest version Completely rebuilding and rewiring PC from scratch Reducing Warzone graphics settings (a lot) Reapplying stock cooler using new paste Ensuring there's no dust in the case Reinstalling Windows and Reinstalling Arch. (btw the problem happened once whilst I was using Arch too) Updating SSD firmware Moving DRAM to different slots Customising Page File size Turning off Windows game boost Resetting CMOS Windows Memory Diagnostic Tool (passed, no errors) I also deduced that this wasn't game specific since the issue seems to occur generally when the CPU is under high load. I've run prime95 on "SmallFFTs" and also "Blend" modes and both seem to make my PC reboot after about 1 minute. I ran HWInfo the last time I tried this - here's the csv which covers about a min before the test starts, the min of test running all the way until the time the PC rebooted. In general, CPU temp never seems to go over about 80 degrees. In terms of software, I have AMD Radeon Software, Ryzen Master, Corsair iCUE, Samsung Magician all up to date and working seemingly happily. Also, with heavy daily usage (e.g. multitasking, working, tons of internet tabs, music playing, stuff downloading, watching hi res youtube videos, driving a 1440p + a 1080p monitor etc.) performance seems absolutely fine and I don't get reboots. Also lower end games seem to run fine. It's just prime95, Warzone and 10 "While True; Wend" .vbs scripts running that seem to make my pc reboot. My conclusions so far I thought it was temperature but AMD say the r5 3600 can go up to 95 degrees C, right? I'm not getting that close. Also, I'm not overclocking. I thought it was DRAM but the issue persists with them even as low as 2133 MHz with XMP off. I thought it was wiring but I rebuilt and rewired cautiously. I thought it was PSU, but my total power draw even with boost should surely be lower than 550 W with decent headroom? I thought it was GPU but the vbs script doesn't use the GPU yet still reboots my PC. My current thinking is that it could either be a faulty CPU, some dodgy MSI Bios settings that I don't generally understand or my stupidity somewhere but I have no idea what to try next except for maybe a Memtest86 since I've seen some recommend that to others. Please, please help - any suggestions welcome! PS, I haven't had any BSOD, and when I try running `perfmon /report`, it seems to take forever at "Collecting data for 60 seconds..."
