I think I might know what you mean now...
Yesterday and today, I've been having issues, mid-game, starting a hosted game, or joining a hosted game where my PC just goes into the toilet...
The screen will go black, monitor power light acts as if my monitor is sleeping, HDD led stay lit, reset button on case is unresponsive, I have to hard power down by hold the power button in for 4 seconds, reboot, and about 50/50 will my program connect to the internet, but DNS for web browsing works find, then if not, I have to restart, computer doesn't, so I have to use the reset button, boot back up, works fine...
I'm at a loss, it started out of the blue, no new mods, no removal of any mods... Just started happening...
[Edit] - This time I just had it sitting idle in the join a server window... and crash, restarts the computer... annoying...
I do recall I've been getting a lot of buffer overrun errors every now and then with Blockland before joining or hosting a server and have to restart Blockland for it to work again...
Any idea?
(Not to hijack a thread, but almost sees like identical issues, but mine happens sooner.
[Edit] - And the first time this happened was mid-game after hours of game play...
