Guild Wars 2

As title says, sometimes during loading screens (this can be the initial load from character select, from pvp back to overworld, or just normal waypointing), my computer will shut down. It doesn’t give any warning, just a moment into the load screen it goes black and my computer turns off. This is only happening with GW2, I tried to make it happen on Witcher 3, CSGO, and Fallout 4 and all were fine.

I’ve monitored temperatures and everything was fine, nothing above 68C on CPU or GPU. My specs are:
AMD Athlon X4 750k (OC’d to 4.4Ghz, haven’t tried disabling it yet but I will soon)
AMD R9 390
3×2GB DDR3 memory sticks
EVGA 700B PSU
The game is stored on a 1TB WD HDD.

Hopefully someone else has had this issue, I can only think either my OC is unstable, but it ONLY happens on load screens which doesn’t make sense if it was CPU related, a ram stick is going bad (these sticks are fairly old, almost 5 years), or my game is somehow messed up.

A system will only usually completely power down when temperature on the CPU gets too high or there is a surge of power into or demanded from the PSU, it’s basically a “panic” to protect the system from harm.

Unstable OC’s/ram sticks going bad will usually just result in system restarts, blue screens and in the case of bad ram corrupt files being written to the disk. For ram you can easily use something like Memtest86 to double check.

For temp issues there are any number of programs you can run while you start up GW2 that will log temps to a file for you to review after a crash to see if anything stands out. Some programs will also allow you to see power demands too like http://www.cpuid.com/softwares/hwmonitor.html but no way for a running log with the free version.

GL with your issue.

Sounds like your OC is unstable as you mention. Either up the voltage if there’s room for that or downclock? to 4.3/4.2 Ghz.

So I fully removed my OC, reverted all settings in BIOS to default, and it is still happening. If anything, it’s getting more frequent. Sometimes now just the game crashes and I send an error report, it’s shut down a few times, and it also restarted once. I know it isn’t temperatures because the max temperature I hit with no OC was 48C on CPU, 63 on GPU (temps recorded in LA). After testing this for a few hours trying to play, I applied slight OC to 4.2Ghz. Something notable is that it’s no longer just during load screens. It happened twice today while waiting for Triple Trouble to start.

In the Event Viewer, a few events line up with my game/PC crashes. These events gave me this log:

Event 19, WHEA-Logger
A corrected hardware error has occurred.
Reported by component: Processor Core
Error Source: Corrected Machine Check
Error Type: Cache Hierarchy Error
Processor APIC ID: 2

I suspect this issue isn’t actually with GW2, just that it has only manifested there so far. I’ll probably go to Microsoft forums or something for suitable for this soon if a fix isn’t found.

Sounds like a power issue.

First thing I would probably do is power it down and rip it all apart. Inspect every connector and slot for any intrusions. After everything gets reconnected and fired up, try turning down the OC if it still reboots.

The fact it happens with Gw2 only is because GW2 is CPU demanding.
Which brings me to a conclusion that the issue is either your motherboardsocket or the CPU itself.

Try running Prime95 stresstest (for atleast an hour, do nothing while it’s doing the test, go outside or something) and let us know what happens.
If your PC shutsdown within that hour, it means your OC is not stable OR your CPU/socket is baked from before.
