Computer sometimes won't turn on when i press the power button
I have a problem where my computer sometimes won't power on, usually it will 80% of the time, but 20% of the time pressing the power button doesn't do anything. When the computer refuses to power on i have to press the restart button for it to turn on. I have the power switch properly connected to the motherboard on the correct pins. Could it be the power supply or the motherboard?
More things i know about my computer:
The cpu has enough thermal grease, and the heatsink and fan are perfect (4200 rpm.).
The cpu is an Athlon XP 2700+ and its average temperature is 50 to 60 C on normal use, internet browsing word processing etc. sounds okay to me
I have cleaned the computer of all dust.
The power supply is an ANTEC brand pwr supply that came with the ANTEC chassis not sure about the model of the chassis. i have had many problems with these power supplies

Gary, Could be power supply failure. Links below for trouble shooting your problem. "I hope this helped you out, if so let me know by pressing the helpful button. Check out some of my other posts if you need more tips and info."
What kind of keyboard is it? Brand or model? Usually these are somewhere on the bottom of the keyboard or right on the front.
Sometimes it helps to completely power off the keyboard and try again, this means removing the battery from the keyboard and try to pair it with your computer.
If you aren't sure how to pair your keyboard with your computer that's where knowing what type of keyboard you have comes into play. Usually there is a button on the bottom to press for it to let your computer know it's available. Sometimes you have to do something else like press a certain combination of buttons.
Actually its not the matter with the Power Supply,but with the CPU Cabinet Power Button.I recommend that you should replace the Cabinet.It will surely help,and for the freezing problem it's your Hard Drive problem,you can also try re installing Windows...!! But for the Power Button problem you should definitely replace the cabinet
IF the system is not turning on any more, try removing the power cable, then press the power button for 10 seconds. then try to power it on again . If it is still not powering up there could be an issue wiht the power supply of the computer. But if it start to turn on, like showing the Sony logo then windows but not going to the desktop. you can try to log on using safemode. you can go there by pressing F8 on the keyboard after turning on the computer. If it still not turning on even on safe mode. there couldbe an issue with the operating system of the computer and needs to be reinstalled.
Thank you for using Fixya, your recommendation is highly appreciated for the free support.
if you press ctrl alt delete, sometimes the computer will reset itself. You might need to wait for a few minutes until the computer does its thing.
if the computer is not moving or you are getting impatient(I am usually impatient). I would usually press and hold the power button of the computer so it shuts down for me. Then I would press the power again so the computer will turn back on.
PLEASE BE WARNED - if you were doing something before this, you will lose your work, and there is a slight chance that the computer might not start back. If it does not start back usually it is a virus or a hardware problem.
Hi, try..... it worked for me. Power Button Lockout is displayed.The
monitor's Power Button Lockout function is enabled. Press
and hold the power button for 10 seconds to unlock the power
The half moon usually means the computer is in SLEEP MODE. Normally, pressing the spacebar will wake the computer up but I have noticed that sometimes, the computer can get "stuck" in sleep mode. If that is the case, you can hold the power button down (until the power turns off and the moon disappears). Wait a few seconds then hit the power button again to turn the laptop back on.
This sounds like your power supply; it's the part that the power cord plugs into that converts the power to dc and powers your motherboard, drives, and everything else inside your computer. You can pick one up for around $30 online or $80 at a retail store.
