At what temperature is the processor and video card consider overheating?

mine has been known to hit up to 180 and was wondering what tempature overheating can cause damage|||My friend do not worry, when CPU temperature reached more about 80 to 100 degree Centigrade the computer automatically shut down. the safest temperature for a CPU is up to 65 to 75 degree Centigrade. And i think your 180 may be in f Fahrenheit.|||Are you overclocking? If so, your system is unstable. "UnderClock" it a little bit so that your temperature goes down. Don't actually underclock it, just tune your clock down a bit. You should not be getting a "Blue Screen Error." If you are not overclocking, I suggest you get proper cooling. Google it up and figure out what will work with your computer (CPU socket type, case size, etc) I suggest never using stock fans that come with the CPU. Hope this helps :D
