Hi,My pc either does not boot at all despite pressing the power button or if boots once then it goes into a cycle where is restarts itself for no apparent reason what so ever. I have Fedora 14 installed on it and it is the only OS. It has been troubling me for the last 1 month or so, otherwise it was working well and I used to work on my pc for hours on end. There is no virus problem as such. All the other parts have been checked with other pc such as the hard disk, CD Drive, RAM, CPU, power supply and even the monitor. But I am still no where near the real cause as to why it happens. Please guide me. Thanks.
