Hi everyone. Fairly new laptop (less than 6 months) which recently has been crashing in a really odd way when doing certain tasks. No BSOD or anything, just straight shuts down. I use Skyrim to test it because it usually causes a crash within the first few minutes. What usually happens is I start up the game, get into gameplay (past title screen loading screen etc.), it plays fine for a few seconds then the fan will start going apebleep and the laptop completely crashes a few seconds after that.
The strange thing is this only happens under a few conditions. The battery setting has to be set to high performance and the charger has to be plugged in. The crashes never happen when the machine is running on battery alone and they still happen when I remove the battery and just run the laptop plugged in.
It doesn't seem to be an overheating issue; both cores stay around 45 degrees even when the fan starts to go crazy (max is 52 and 49). Changing chargers didn't help either, both the one that came with the laptop and a store bought one lead to crashes.
Laptop is a Toshiba Satellite s50t-B running windows 8.1
i7 4510U cpu
AMD Radeon R7 M260
Really appreciate any help at all. Thank everyone.
