Computer Automatically Turns On After Shutdown: ATX Akyga 550W, Asus P5KPL-AM, Win XP

Hello. Yesterday I turned off the computer then I come to the room to watch and it is still on. I turned it off and I am looking at what is happening, the computer turned off and turned on immediately. I think it is the fault of the power supply, but I prefer to ask in the BIOS, but I have not turned on any option related to it. Power supply: ATX Akyga 550W LPG12-35, motherboard: Asus P5KPL-AM and Win XP. Please help

So far, the problem is very easy to solve: When you leave the house, disconnect the computer from the power socket. You have to wait for a more professional solution.

Moderated By Matuzalem:

For such "professional" advice, pursuant to clauses 8.1 and 12 of the Regulations - a warning.

If it was okay before and you didn't change anything in the BIOS, try with a different power supply.

Check that you have not switched with:

You often click on OK without reading what is in the window ...

Grounded sockets ATX Akyga 550W LPG12-35 power supply and how to check the condition of the capacitors, I do not know

https://www.elektroda.pl/rtvforum/topic1221090.html - see the screenshots.

the condition of the capacitors is good, they are not swollen or spilled. On request, I can upload some photos of my capacitors

So what should I do to replace the power supply?

And did you check the BIOS settings as your colleague Gusioo suggested?
Set exactly as shown in the picture, if you have otherwise :)

I have the same as in the picture

power supply to replace or what?

It is worth starting with checking on a different power supply, or maybe updating if you have an old BIOS version.

my bios version; u is 08.00.12 not updated

1) Right click on "My Computer"
2) "Properties"
3) "Advanced"
4) In the "Startup and Recovery" field you click "Settings"
5) You uncheck "Automatically restart".
6) You approve 2 times approx.

Then shut down the system and write if it displays "Blue Screen of Death".
If so, look for the error code in uncle google.

In the system properties - tab: "Advanced" -> "Startup and recovery" click "Settings" and uncheck the box "Automatically restart".



Then shut down the computer and see if there will be a "blue screen" with the error description?

edit:
sorry for the duplication - we wrote at the same time

"After selecting shut down, the computer restarts
ATX standard computer
- Check if our PC supports ACPI
In the device manager / Computer we should have information about the computer in the form of, for example: "Single-processor PC with ACPI interface", it means that our computer supports this mechanism and you should:
- Disable splash screen and fast user switching
Control Panel / User Accounts / Home / Change the login method and uncheck the items there
- Uncheck automatic restart (PPM My computer Advanced tab Startup and recovery / Settings Automatically restart)
- Check if soft is not installed:
- Easy CD Creator 5.0 (Roxio)
- Direct CD 5.0
- Logitech mouse driver
- Zone Alarm firewall.
Uninstall
- In the registry, add the DWORD PowerdownAfterShutdown value 1
under HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon
- Check if ACPI Support is enabled in the BIOS, update the BIOS
- Install, activate NT APM / Legacy Support
Installation: Control Panel / Add Hardware / New Hardware Device / NT APM Support / Legacy
Activation: Device manager / View / Show hidden elements now should be NT APM / Legacy Support now below with PPM turn on APM / Legacy Interface Node

If it does not work and the computer does not have an ACPI interface or in Bios the scheme has been changed to AMP
- Control Panel / Power Options / Advanced Power Management APM roll up options Enable Advanced Power Management Support "

will it help to reinstall the system?

F8 select Last Known Good Configuration options. If you manage to run, check the disk for errors and then sfc / scannow.

Reinstallation will theoretically help, but if, for example, the driver is at fault and you install it again, the problem will return.

Try to scan your system maybe it's some virus.

There is not enough data for this message. How can you put a photo in it, how does it look like in full?
