Hello

I havea Dell inspiron 1525. It's 32 bit and runs on Vista.

This morning it just shut down on its own. No blue screen or any other message. I went into event viewer and saw this message:

'The process C:\Windows\system32\winlogon.exe (OWNER-PC) has initiated the power off of computer OWNER-PC on behalf of user Owner-PC\Owner for the following reason: No title for this reason could be found
Reason Code: 0x500ff'

I have no idea what it means. Please can anyone help.

Thanks.

500ff errors are system failure's. This is usually caused by a flaky 12 volt line in the power supply. The line voltage drops causing a shutdown. It may also be the motherboard not being able to use the 12 volt input from the PS because of marginal power tracings on the board.

Suggestion for you Elle8 while SRX660 is away, try running the laptop off the battery only and see what happens, if the issue reoccurs, whilst the laptop is off remove the battery and try using the AC adapter only, again see what happens, if either is found to be faulty the links below may help.

Another possible cause may be overheating, when if ever was the last time the inside of the case was cleaned out of heat trapping dust?
A video for you to watch you can use this http://www.alcpu.com/CoreTemp/ to check the CPU temperature and this http://support.micro....com/kb/2001061 for information on shut down codes.
