I'm hearing a clicking sound from my power supply and my computer does not boot up. I have noticed that the red light is blinking on my cpu and the cd rom drive's green light is also blinking. If i open the cd rom the computer boots up, but when i inserted a cd and close the cd rom the clicking sound will be heard from the power supply and the system shuts off. pls help.

HP server ML350 G3 won't boot, red internal health LED
2004 time stamp in the manual, so is 15 years old, (a relic really)
and old Generation 3.
1: does the 2 fans blow, 1 in PSU , and CPU ? this be first.
sounds of that is first or you have no power or PSU is bad.
(most the time)
2: does the screen show anything, at all?
like (no signal, no sync, vga cable not connected, or the like?)
or is the screen dead,. 100% dead
ever change out the RTC coin cell inside, they don't last this long,
did you know that?
14 year old coin cell is impossible to be good. a $2 fix too.
if the coin goes bad the BIOS goes nuts, due to loss of data
in the NVRAM the coin cell powers.
replace that then do a BIOS reset, and now it ill boot to HDD 0
if and if HDD is good and if the OS is not corrupted, none stated.
Sounds like a startup self test. All wireless devices go through a power on self test. Does it connect? You can connect to it and go online? I rarely turn mine off, only in a electrical storm.
Believe it or not it is probably your Power Supply. Just because it lights makes the system lights up does not mean it is working properly. Sometimes it has enough power to make the light glow, but not enough power to make the fan in the power supply start or any other functions.
You can also try the things below to see if they work, if not replace the power supply.
When you plug in the power cord is there any lightswhatsoever on the computer?
When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the computer is trying to boot or may have booted, butthe screen is not showing for some reason.
Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous. Most times the problem is with the Memory or Video Card when you hear beep tones or blinking lights. Notice the pattern of the lights and blinks. Do you get 1 Long Blink or Beep? Maybe you get 1 Long followed by 2 Short Blinks or Beeps.
Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button.
Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.Memory Chip might be bad. Remove the Power Cord, Open the Case and remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.

No Display, so does it seem like the computer booted up and is running except that the Display is black? Do you hear fans running, disk drive spinning, blinking lights or beeps?
I'm going to assume that in your case since you mentioned a red light that it is not booting up all the way. Therefore your problem is probably with the memory, the video card or some other motherboard issue.
Remove the Power Cord, Remove the Battery, Remove the cover that houses the memory on the bottom of the laptop then remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.
How many blinks? Count and notice the patterns of the blinks (3 long blinks or 1 long blink followed by two short blinks).
Remove the Power Cord, Open the Case and remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting.

Remove Power Cord then press and hold the power button for 30 seconds, then put the cord back in and try to start it.
When you press the Power Button are you hearing the fans run, the disk drive running, the cd drive click and the light on it comes on for a second or two?
Anything shows up on the LCD Screen?
If you press the power button and absolutely nothing is happening then you most likely have a bad power supply.
If you press the power button and you start hearing beep sounds or blinking lights in a continuous pattern (ex. 1 long followed by 2 short) then you have a motherboard issue. Those beep sounds and blinking lights tells the technician what is going on with the computer.
When you press the power button do you hear the fan running, hear the disk drive running, see any lights, do you hear the cd drive click once and see the light come on briefly on the cd drive door? If you see all the aforementioned then it is surely trying to boot. Computers don't boot mainly because of the following problems. 1) Bad Power Cord or Power Supply. 2) Electro Static Buildup. 3) Bad Motherboard 4) Bad boot or system files. Remove the Power Cord and the battery if it's a laptop. Press and Hold the Power Button for 30 Seconds. Then replace only the Power Cord and try hitting the Power Button. If it boots you had an Electro Static Buildup. If you have boot or system files that are missing or corrupt normally the system will be telling you that on an error message that appears on the screen. Does your system show you anything on the screen when you press the Power Button? If not you have a Power Supply or Motherboard issue.
