Have tried multiple options to stop the pseudo-crashes - lowering to 32 bit client, adjusting lots of graphics settings including the resolution, lowering to dx9 from dx11, and always within 2-3 minutes of loading the game, and sometimes while at the character screen, it does a pseudoi-crash, where the system appears to sleep. It turns itself off and when I turn it back on everything is still running, including lotro. Very strange and I can’t figure it out. The fan runs like mad from the initial splashscreen, which is why I was thinking about heat, but at the lowesr graphics settings, the crashes still happen and the fan still runs like mad. Very odd.
