Ivan, again. This "IRQ not less or equal" error has nothing to do with overheating or some hardware damage, this is strictly a configuration error of the operating system.
IRQs are used by hardware device drivers, so in order to get to a solution you should
- tell me more WHEN that error message appears (at startup, during standard work, when playing videos, during internet access), what are you doing at the PC at that time
- post the complete "IRQ not lee ..." error message here
- if it happens at startup (i doubt since you still get online in AIM
try starting the PC in "safe mode" and take a quick look at the last line on the screen BEFORE that error message appears.
So i need information, information, information ...
