Timmy's computer was acting up. the power switch would not work no matter what. he kept trying to push it in harder, took off the front panel to press the little button inside, even took it off the power outlet and put it back in. there IS electricity, all cables connected and otherwise all the components work. after some fiddling, he's finally able to start his computer with the same ease as pressing the power button. what did he do?

Award bios = CPU overheated. Phoenix and other bios types do not have a continuous hi ptiched beep, so it's the CPU overheating. Now, given the new power drain on the PSU and the fact that the CPU overheats, PSU was either bad or not sufficient (or both!!) :) Solution 450-500 wt quality PSU. Probably had a stock 300.


Well you need to look up the definition of POST

POST = Stands for power-on self test. Each time a PC initializes, the BIOS executes a series of tests collectively known as the POST

Well those POST codes do not apply for when a computer locks up after the computer itself has already been booted and passed the initial POST. He also had a 400wt PSU which was a quality PSU according to the readings on his voltages.
