Hi, I am new to this board and looking for a little help. I have a Compaq Presario s4020wm desktop which is about two years old. I have never had any problems with it yet. Now, when I turn the power button on, the yellow light flashes once, the CD drive light flashes, but nothing happens with the computer - it does not boot at all, not even into a welcome screen. It seems to run internally for about a second, and then just sits there. I think the monitor is fine, because the monitor comes on with a "no signal" message when I disconnect it. I have tried to take out the CMOS battery and put it back in according to the only advice I received from the Compaq website. I also tried testing all of the internal connections to make sure nothing was pulled out or something. I am looking for any suggestions, tips, and ideas about what is wrong and what I can do? I don't have recovery discs because Compaq does not ship them with their products. Thanks in advance for your help. It is appreciated. Also, if I need to buy another one, is it possible to take the hard drive from my old computer and move it to the new one?? What if I get a laptop?
