this souinde like your power suply switch is turned off. if you look on the back of your computer were the power cord goes into the computer thats your power suply. if you look closly there is a switch on there this switch proble got shut off. you wanna make sure it is turned on.
Does the PC do graceful shutdown or shuts down straight away?
If it does graceful shutdown perhaps make sure you are not pressing a shutdown button or sleep button.
If the PC shuts down completely without warning first thing to check would be the fans and interior of case in case is full of dust.
Hi, As u would 1st know that there is a perfect power supply of 220-230V, & if Yes try replacing the SMPS, If you still hve the same prob thn its, Motherboard problem, As i am a technical person & Faced many problems like these.......
Is it possible that you have changed the settings of what buttons do what on your system? E.g. you could have changed the power button to "switch user" instead of "shut down", to check this (in XP) go to "Power Options" (in Control Panel" and then click on the "Advanced tab" at the top, then select "Shut down" from the drop down menu at the bottom of the window.
If this is already set to shut down then maybe you could do a system restore in case another setting has been changed, restore it to before the PC started doing this.
Alternatively try actually choosing "Turn off Computer" from the Log On screen (press Ctrl + L to get to this screen, or choose switch user/log off). If you are using Vista I beleive that there is a shut-down option from the Log In Page there (which again you can access by pressing Ctrl + L on the keyboard.
go to control panel>administrative tools>event viewer and look in the left hand listings at programmes etc and see if there are any red crosses or exclamation marks to give a clue as to the problem, but if you know it's not overheated and you have'nt recently installed any other software and recently scanned for virus and spyware it is probably a driver problem.
