    I have a P4 3.00GHz with 1.00GB of ram. When i first start it up after about 10-15 mintues it shuts down. I then have to wait 5 mintues before it will start up again. It will then run fine until i shut it down again. Has anyone got any ideads on what the problem might be.

    When the PC shuts down, does it shut down instantly. Do you get a blue screen of death (microsoft error) prior to shutting down.

    It could be one of thousands of problems. Over heating components, lack of sufficient power supply, software conflicts etc...hard to say.

    It shuts down instantly. Also i failed to state that the fan starts going very fast and gets very loud before it shuts down.

  4. Sounds like overheating.

    Try taking the side of the case off and pointing a desk fan at it. If it runs much longer like this, then overheating is the cause.
    All you have to do then is determine overheating of what

    If you take the side off check the fins on the heatsink to make sure they are not packed with dust. Same thing happened to my brother, he never dusted them out and once the hot weather hit it was just enough to put it over the top.

  6. It could be the CPU heat sink is not properly glued to the CPU or that the bond has been weakened/lost. In such as case the CPU can get hot quickly. When the temperature gets too high the BIOS will direct all the fans to increase speed to compensate and cool down. But if the CPU does not cool quickly enough, the BIOS will shut down the system immediately.

    Have you physically moved your workstation recently? I saw a similar thing happen when a user of mine moved their desk and workstation. They had bumped into the case and there was a short on the board. A long shot I know. Also, look for physical damage to the power supply. I had one that the wires melted on me after a power surge. You could see the damamge until you took the PS out because it was on the other side of my view. You can pretty much rule out memory issues or software conflicts, since they rely on 1's and 0's, which require power and you said it won't power on. If you have an onbaord video card in addition to an AGP/PCI card, try removing the addon card and using the integrated one. The add-on probably has a heatsink, and maybe a fan, they could be causing the issue, but my guess is that your power supply is on it's way out the door.
