Having problems with your Dell Dimension 8400 PC Desktop ?

I got the steady Amber light of Death in my dell.

\015 I do not have the system specifications, my problem is that when I turn on my pc it turns on with a steady amber light it's not the first time this happened tome it's about the third, the other 2 times before I just unplugged it disconnected everything and kept connecting it back for hours until it turned on and had no problem for about a week, then when it happened I spent 3 hours disconnecting and connecting it back until it turned on but that same day I got the steady amber light of Death, the thing is when you get the steady amber light of death no diagnostics light turn on, when I turn it on my power supply fans turn on and it glows blue, the motherboard light turns on also I changed the 3v Cmos battery on the motherboard, I checked all usb ports and they were ok no pins were bent, right now I did the same thing I disconnected everything and connected everything back and nothing happened, I tried the password reset jumper. If it was the motherboard would it have turned on the first and second time? If it was the power supply would it have worked before to? I am out of ideas and my patience is wearing thin, any advice would be useful thank you.\015

Answers :

As a hardware repair technician at a local university, I have seen the amber power light problem on quite a few Dell computers. If the machine is in warranty, Dell insists the power supply be the first thing replaced, even if it tests ok. If that does not do it, then they send me a new motherboard. Of the dozens of machines that have had this problem, only 1 of them needed a new motherboard. The power supply alone resolved the problem on all the rest. I have found this to be true on out-of-warranty systems as well.
Sounds like you are having northbridge heating issues. the motherboard has a sensor on it, and if the northbridge gets too hot, it will not let the computer come back on, to protect the cpu.

make sure your fan is running on top of your cpu. unplug the power cable for an hour, then plug it back in. keep your case open for now to let some of the heat out, if you have a floor fan, it might be a good idea to have it near to help circulate the air.

I am guessing you have 9800 model graphics card? These need a lot of space, and give off a lot of heat. Buying a 90$ case that has better circulation could fix all your problems. You will know, if the computer works with the side open.

Do not put your case in your closet. It will get too hot in there.

My Dell Dimension 5000 is stuck with a solid amber light on the power switch and solid amber light on the motherboard. Switch 'clicks' ok but light only goes out when power lead removed. No fan, no bleeps, no bootup, just solid lights. The 5000 doesn't have other LED lights to assist. The PC got into this state after local power cut, when power returned. I've changed psu today -- exact same condition. Any advice would be appreciated
