Question about System Power Supplies

1 Answer

Power supply stopped working

I received my Dell computer for Christmas 2006. The power supply quit working in August and my husband (who is a mechanic) was convinced that the power supply had a fuse in it and attempted to work on it making it's warranty void. I purchased another Dell power supply block from a local Computer Company. Today, this one quit. Is there a problem with the power supply itself or do I have a problem with my laptop??

Most of the time you need to replace the mother board as well as the power box, it shorts the mother board out.

Computer acts like it in standby mode will not power up, made a weird noise according to my daughter and quit


Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them there probably old and faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they are probably old and faulty a computer needs its connections to have an end so any faulty leads will end up with a computer error

hope this will help

Dell 4400 Main power in house went off while using my computer and then went back on about an hour later. Now when I try and restart the PC, the power button light turns yellow like it is in sleep mode...


The power supply or mother board probably went out. Did any other items in the house stop working? This happened to me years ago and the electric company reimbursed me for damages.
You can try unplugging the power cord for a few minutes, then retry listen for any beeps from the computer. If it is powering on but nothing on the screen and no beeps *********** board is probably toast.

I have a flashing light on the fan end of the Dell power supply and the tower won't power up.


A flashing light is suppose to mean that the power supply is receiving voltage from power cord but is not functioning correctly. Here is a page with the information.

Have a yellow amber light blinking


A Blinking Amber or Yellow power button means that the power supply is receiving power from the source but is unable to properly distribute it to the components. This can be caused by a defective power supply or a defective motherboard. Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

Humming noise


IT sounds like the fan bearings are going out already, or have flat spots on them that cause vibration at speed. Try calling the manufacturer and tell them the fan either quit working or is about to quit.
