Re: Power supply doesnt turn on

There are several solutions

1. Plugs should be placed correctly
2. The should be power comming into the sockets
3. The voltage switcher should be on the correct voltage... it may be on 220 V while your power in your country would be 110 V so check it

4. Fuse may be blown out

if the 3 dont work contact me again if the fuse may be blown out,, it may be a greater problem

Fan is not moving, front panel led is red

If your computer will nor start and the system fans do not turn on and stay on when you power on your PC, then either the power supply has failed, a component connected to your motherboard has failed or the motherboard itself is defective .
Power supplies require a "power good" signal back from the motherboard before they will operate.. In order to test a power supply, you need a PC power supply tester. Without one, you will either have to take you power supply to a PC technician and have him test it or install a known good power supply in your computer.

It doesnt come up and reconize this item when i plug it into my computer , as a mass storage device , how do i get it to open so i can look on the device? and if i cant open it did this download anything...

If you do not have a power supply connected you probably need the dual usb cable (two usb connections on one end just one connection on the other) Most USB ports do not have enough power to spin a disk without some help.

Raidmax 500w power slowly died, then wont turn back on.

1.-Your CPU fan is working?

2.-Your Power supply fan is working?

If not and following your description I think that you have to replace your power supply.

If you have the light on in the motherboard doesn't mean that your power supply is good.

Check the first to points above and if 1 and 2 are not working

Replace your power supply.

Let me know how it is going!

Thank you for using FIXYA!

Power but doesnt start

Sounds like you are not getting a "power good" signal from the mobo telling the power supply to turn on. Something is probably wrong with the configuration or installation of parts. Try removing the RAM and all interface connectors and then see if will power up.
Make sure the power supply is set to the correct A/C voltage for your reigon.
Could be the motherboard is cmoing into contact with the chassis or something else.
Make sure the processor is inserted correctly and seated.

If it powers up. begin connecting the RAM and try again. Keep connecting something else one at a time until it fails. That will be the problem.

Flashing Lights when powered down

The flashing LED is because your system is in "sleep" mode. By default windows Vista puts your computer in sleep. What this means is it doesn't shutdown the power completely it leaves a little going through certain computer components (more specifically the ram) to speed up the boot time when the power button is pressed again.

In XP a the default shutdown scheme is a complete shutdown where power is turned off after the shutdown process is done. If you are using XP you are putting your computer to sleep when shutting down.

As for the boot problem. Newer motherboards have an LED on the actual board to indicate that it is receiving power. If it is of either the power supply switch (at the back of the case) if off or the motherboard connection is loose and the shaking makes it fall into place. (Shaking is usually not necessary and indicates a problem...)

There are a few possibilities I can deduct from your description:
  • the connection from your power supply to your motherboard isn't properly seated and is causing this
  • the power supply switch (not the case switch) is being  turned off and results in the computer taking a few seconds before the internal LED become solid
  • ... the dreaded sign that the power supply is failing and is on it's last legs...
My suggestion is to check all connections and if that doesn't work borrow a power supply from a friend and swap them to see if it boots properly.

(If a friends with a spare power supply isn't an option a local PC repair shop should be able to help you out... but probably for a fee...)
