The topic says it all. I am encountering the situation where my system will stop certain actions, to include file transfers (like moving large numbers of files via USB) and in games like World of Tanks and Star Wars: The Old Republic. In the latter game, I would get dropped out to the server selection screen or character selection screen. In the former game, WoT, my tank will continue whatever I was doing at the moment the lock-up starts. So if I was rotating in place, the hull will continue to spin on-screen while I retain control of the turret. This lock-up will continue for ~10 seconds.
Within the last few minutes of playing WoT, I noticed my CPU fan spinning loudly before my tank became unresponsive twice in one match. Any thoughts as to if cooling might be the problem?
Yea if something overheats, your system will shut down to prevent damage. Check your temps with the speedfan program. If they seem high try reapplying thermal paste. If that doesn't work, then get a new cooler.
I know how you feel about WoT. One time i lagged and drove into a lake. It sucked because I was top tier so my teammates depended on me.
