Skyrim brutally shutdown my PC after 3-4 minutes

[ApheX2]

Hello,

 

I've an issue with Skyrim Legendary. After 3-4 minutes of playing, it shutdown brutally my PC (without prompt, instant shutdown, like if someone pulled off the power cable, then after 2 sec, PC boot).

Strange issue is that I played Skyrim 2 months ago with 200+ mods without any issues. This time, I've only 3 mods:

 

Here is my skse.ini content:

 

[General]

ClearInvalidRegistrations=1

EnableDiagnostics=1

[Display]

iTintTextureResolution=2048

[Memory]

DefaultHeapInitialAllocMB=768

ScrapHeapSizeMB=256

 

However, I play a lot of game without any issue like this: WoW / Overwatch / PUBG / CSGO etc.

I monitored CPU and GPU temp and load using MSI Afterburner. Temp seems to be fine at the shutdown time:

 

So I guess the only possible hardware issue is my PSU. But why only on skyrim? I played a lot of more recent game (like Witcher 3) without issue.

Here is my config:

 

i5 2500K @3.3 ghz (no OC)

8gb DDR3 ram

GTX 970 4gb (no OC)

MSI p67a-gd65

PSU Corsair HX 850W

144hz benq zowie monitor 24"

Win-7 64b pro

 

 

Thank you for your help :smile:

UPDATE: a totally vanilla skyrim (default ultra settings .ini and no SKSE) seems to not have this issue.

So here is my skyrim.ini & skyrimprefs.ini tweaks done via MO, maybe it can help:

UPDATE: Ok so I made further testing, to see in what conditions Skyrim shutdown my PC.

 

• Default Skyrim (no mods) with default ini (no tweaks) => NO SHUTDOWN
• Default Skyrim (no mods) with tweaked ini (see post #2) => SHUTDOWN after 2-3 minutes
• Lightly modded Skyrim (see post #1) with default ini (no tweaks) => NO SHUTDOWN
• Lightly modded Skyrim (see post #1) with tweaked ini (see post #2) => SHUTDOWN after 2-3 minutes

So it seems to occurs only when I tweak my ini. However, I still don't understand how an ini tweak can shutdown my PC... A CTD okay, but a shutdown? Strange.

That is rather odd. Have you tried using Bethini to tweak them Ini files?
