My girlfriend's grandmother gave me her Dell XPS 400 desktop to look at since it won't boot up. I brought it home, dusted it out, then tried to boot it, but had no luck. It did give me an amber light that blinks on the power button. I ended up taking out the P2 connector to the motherboard and the computer then turns on, but I can't get it to show video. When I reconnect the P2 connector I get the same amber light blinking on the power button.


I read the manual and it says an amber light means something with the power connectivity, so I'm guessing it's the PSu, but I figured I'd still ask here to be sure. What you guys think?
 
Okay, here is a list of things I've done so far:



- Checked to make sure DVI cord is plugged into monitor and it has power

- Checked capacitors and all fine

- Took out CMOS battery; result was amber light still blinking

- Dusted computer; result was still amber light blinking.

- Switched ram around in diff. dimm slots and even tried other working ram; result still amber light blinking

- Put in my 7800GT (surprised it fit); amber light still blinking.





Now again, when I took out the P2 connector out of the motherboard, it gave me a solid amber light and everything booted up, but I still got no picture. I could hear my videocard up and running. I hooked up the dvi cord to both connectors on my videocard just to be sure I was putting in the right one. When I put in the P2 connector again, no luck.



I'm trying to think of anything else that would be helpful. The only other thing I know of really would be to switch my HDD in there to test that out, but I really doubt that's it. I tried to find the lights that are supposed to tell you what is wrong with it, but I didn't see them. I think I'm just going to buy a PSU, but I don't know which one. Could anyone tell me what PSU would work because I'm reading stuff about a BTX case and not sure if any PSU will work with this.


Hopefull that helps some more.
