Hope someone can help me with my problem. Dell tech support has been useless. I have a Dimension 8400 with Windows XP. I have been having this problem for months. When I turn on my computer, I hear six beeps and the computer does not come on. The diagnostic lights are A and B yellow, and, C and D green. I turn it off, and restart it and it comes on. After chatting on line with Dell technical support, they finally replaced my memory. The following day, the same thing happened. One tech person had me change something using the F2 key, but, sorry to say, I have no idea what I did. I just followed his directions. That did not work either. Another tech person told me to use PC Restore which I did to no avail. They also had me do Last Known Good Configuration. It didn't help. I sent them an e-mail on December 20, but, got no response. I decided to wait until the holidays were over before I contacted them again. But, I thought I'd to ask you guys first. The problem isn’t happening every day. It happened the first four days of January, but, the last five days, it has stared fine. Any suggestions you may have, I will pass on to Dell. Thanks for any help you may give.
