Computer switches off at startup

  Alan H 11:35 16 Mar 03

Switch on at wall switch on computer. It begins to load up. First black screen loads all devices OK but second black screen comes on and computer switches off! Have now cleaned inside case (Quite clean) and checked all connections. Any suggestions as to what to try? This only started 2 days ago. The computer does sometimes come on but seems to be working slowly when it does.

Have you added any hardware 2 days ago?

With it switching off so soon, the first thing that might be worth checking is the cpu fan.

With the case off, ask some one to turn the machine on. Have a close look at the fan, is it spinning from startup?

Check Power Supply Unit, try it out by disconnecting power supply to cd/dvd drives see if the pc starts up, if it does you need a psu.
