With proper design, they run 24x7. Try this. Leave the case cover off. If that cures it, talk to the machine's maker.
BTW, PC Life is about 5 years. Power on tine is what you seem to be asking.
I want to know whether PC should be shut down for cooling after it has been continuously used for some hours.If yes what are the maximum number of hours that it should be kept on?
Also what is the average power consumption of 17"Samsung Monitor (Samtron 75E), Mercury SW-880 Speakers, & P4 CPU.
Please help me out
