my system is about 5 yrs old,. it has started to show thermal problems now. should i try to replace the heat sink arrangement as the system freezes after i load a game for 10 min or so.. i have changed the thermal compound in between but it showed no improvement..
after a connected a case fan i can run up to 1 hr before automatic shutdown .. pls help...
You connected a case fan and your machine ran much longer than before (one hour vs. ten minutes.) That seems pretty suggestive of heat building up in the case causing the CPU to overheat, which means you have inadequate airflow into and out of the case. I would first suggest dusting out the entire case well, particularly the air intake in the front of the case. There is probably a lot
of dust built up in your case if the machine is five years old and you've never dusted it out enough. Then if that's not enough, consider adding another case fan or two.
