My Computer Keeps Restarting Without Warning

Topics Computer, Hardware on August 17th, 2007

Does your restart without any prior warning? You do not need to worry about this. We have the solution for you. This problem could happen at many levels. So lets start step by step.

Are you able to boot into the OS? If yes then at least your “Restart Switch ” isn’t getting short. But could be a super sensitive switch or a bad power switch too which creates the problem.

Now check if your is set to /sleep after certain time. Maybe it has problems going to sleep and can’t wake up, or restarts upon awaking. Disable this in your OS as well as in the BIOS (if there is an option).

If above two are working then its time to check the power supply. Here goes a small intro of how the power supply works.

If the voltage from the wall outlet or from within the power supply [faulty power supply] falls outside the tolerances required by the , the will . This happens because the power supply constantly sends the motherboard a power-good signal, for example, if the power supply cannot maintain that are within tolerance, the power-good signal is withdrawn and forces the system to reset. The system will not restart until the power-good signal returns. The power-good signal may be absent for a second or less, but that will still force the to reset.

This point has to do with proper power being supplied.

Check your wall socket for proper voltage. If you have the hooked up to the same line that goes to heavy power draw devices, such as an airconditioner, microwave oven and so on, does your system when one of these devices is running? If so, you may need to change the outlet that you use or may need to run a new line to your , dedicated to the .

    Now check if your computer is set to standby/sleep after certain time. Maybe it has problems going to sleep and can’t wake up, or restarts upon awaking. Disable this in your OS as well as in the BIOS (if there is an option).(more…)

    My computer Keeps restarting with out warning.I could be surfing the net or checking my email or playing a game and it just restarts.I only changed the Fan on it because thought it was over heating but wasnt the case the temperature would be at 45 C not a problem I think. Also put a fan in front of my case with out the side screwed on and it still restarted on me. It wouldnt happen when I had it pluged in a socket.I have a Anti Virus and I always scan for viruses and nothing appears. But need an urgent response quick.
