Computer turns it self off and won't turn back on.
My computer is only a few months old. I have it connected to the power through a UPS device as our house has electricity surges quite a bit. In the last few weeks it has started turning itself off. I then can't turn it back on - pressing the power button
does nothing, also, the reset button does nothing. I can get it to start again by taking the power cord out for a long time - at least a few hours - and then it powers straight up again. Once it starts back up it works fine until the problem happens again.
I have tried changing the power settings to stop it from going into sleep mode but this hasn't worked, the problem still occurs. I have also tried pluggin it into different power points, but this makes no difference. Please help.
Keys to the Problem Computer turns it self off and won't turn back on.
If this happens both with and without the UPS between the machine and the mains I suspect the system power supply unit (PSU) is faulty.
It might also be a capacitor breakdown on the motherboard.
Substituting a known good PSU would be the first step to see if the problem recurs.
- Click the Start button.
- In the Search box, type "regedit" (without quotes) and press Enter.
- Look for the following registry key: "HKEY_LOCAL_MACHINE\SOFTWARE\ Microsoft\ SQMClient\Windows\DisabledSessions".
- On the right window pane, delete the subkey: "Machine Throttling".
- Restart your system.
