Red power light on, making a noise but won't switch on/off
I have a red light on the power led but it won't switch on/off. Was just working on the PC and it just went off. It appears to be making a noise (fan?) but nothing on screen. Have tried turning off at plug, have checked connections and have tried holding power button in but nothing seems to be working. Can you help as am a bit stupid with these technical things!!

Blinking of power LED are fault indications. Count the number of blinks occur at one time switch on. For this number, you can get an idea about the faulty section circuit inside it. It will make troubleshooting much narrower. If you wish to get more details about the blinking codes, check this link. Pull up older posts there.
Led's only work one way, so it does'nt matter what colours they are. The led's that they connect to will only work when the plug is the correct way. You wont do any harm if they are wrong, you just turn them round. Plug them in one way and if the led for the hard drive does'nt come on then it's the other way. Same with the power light. The power switch when pressed just makes a momentary connection across 2 pins, so it does'nt matter which way, it's just like touching the pins quickly with a piece of metal.
Annoying! happens to us too frequently, but this works. We ended up buying a new one and returning our broken one after owning for three months
5. Turn on the Nursery Unit using the On/Off switch on the side. The green power light should come on.
6. Within a few seconds, the Parent Unit will lock on to the Nursery Unit and the top four (4) green LEDs will shut off.
A second later, you will hear a series of beeps and the connection LED should change from red to green. Your monitor is now
ready for use.
7. If the top four (4) LEDs do not shut off, power off the Parent Unit and the Nursery Unit and repeat steps 4 and 5 above.
8. If the connection LED on the Parent Unit does not change from red to green and the unit begins to beep, press the
channel "ch" button on the Nursery Unit. Within a few seconds, the Parent Unit should lock in on the Nursery Unit and
the connection LED should change from red to green. You may hear an audible beep during this process.
9. If the Parent Unit is still unable to lock in on the Nursery Unit (connection LED will be red and the unit will beep), power down
both the Parent Unit and the Nursery Unit. Wait for 10 seconds then hold the volume down button on the Parent Unit while
pressing the On/Off switch. When the unit powers up, you will hear a single beep and all of the soundlights will illuminate.
Release the volume down switch and within 2 seconds you will hear two beeps and all of the Sound Light LEDs will stay lit and
the bottom LED will be red.
10. Repeat steps 5

On a computer mainboard there are usually a number of connecting pins right next to one another called RESET, POWER LED, HD LED etc. The power led often leads to the green LED next your power button to show that the juice is available and on. The cable that leads to the red LED is usually the HD LED which shows that a disk drive is being accessed. Since the red LED is active, one of your disks is probably being accessed and that's where the problem is. Either the disk is damaged, the cable is still not inserted properly or the bios is having problems identifying one of your disk drives.
1) Power the computer off. Take the power cable out. Make sure that you are grounded (have no static charge on your body). Take all of the cables between your mainboard and your disk drives off. 2) Plug in one of your disk drives, reconnect the power cable, switch the power on and watch the monitor. If all goes well you will see that the bios has recognized the disk drive and will simply display a message that the operating system for example isn't available or no harddisk drive is present (if you connected something other than a harddisk drive). 3) repeat this process with the other drives, powering the pc completely off each time and then adding a new disk drive. 4) once you've reached the point where the red LED drive is displayed but no message is available, you've found the culprit that is keeping your pc from booting properly. Hopefully the cable has just been stuck on improperly or the cable is damaged (Check it), rather than you having disk drive damage.
i never had green lights on my motherboard, they have always been red and it runs fine. the mother board was made with red led lights. if its not working right, it's probably the switches on the mother board, normally make the first switch on, and the other 3 off.
