I have a computer which when left off for long periods will not start up. The light on the front (this is a new dell dimension desktop) turns yellow and the computer does not boot up at all. While attempting this process you can hear the computer trying to start but it sounds as though the computer is not getting enough power. After 4 or 5 times of this process it seems to start up and boot normally to the windows xp screen. I opened it up and removed all the hardware and made sure it was all seated properly. I then called Dell tech support which is like pulling teeth. After 4 times on the phone going through the same processes over and over I have gotten nowhere. If anyone has any ideas or knows how I can get in touch with someone from Dell who is not in India doing everything they can to keep the computer where it is and not helping then that would be great. Or if someone has a good idea of what is wrong then that would be good also. Thanks.
