On Saturday my Acer 1.5Mhz P4 started powering off. There have been no power failures. When I notice it has stopped working I see that the power light is still on (or back on). I press the power button and it boots and comes back up. 3 or 4 hours later it goes down again. The CPU ans power supply fans are working and there is no dust buidup inside. Any ideas what is going on?
Thanks.
Thanks.
