Green light on back of computer blinking/ticking

[Davda]

    I have read many many articles about the problem I am having but none of them have helped me to solve my problem. (probably because I don't understand them) But anyways here is the story of what happened. I walked into my office and saw that my computer was frozen. So I turned it off and then turned it back on but when I did it beeped three times and wouldn't turn on. I had no idea what in the world was going on so my dad told me to unplug the power cord for a couple days. I did so but when I plugged it back in and pressed the power button it did nothing. I looked at the back of the tower and there was a green light blinking on the back of the computer. I took off the case and I saw a light on the motherboard also blinking. I have no idea whats going on. Please help me.

Oh and P.S. I am only 14 and know nothing about computers so please try and simplify your responses.

The green eight is not related to your problem. That is from the network thing. When the computer is plugged in, a very small bit of power goes to some things.

It is possible that part of the Power Supply has gone bad. Or maybe a drive has failed and shorted out the power. Or, it could be the power switch has come loose.

The green blinking light on the MBoard however IS related to the issue...
What MBoard is this ?

   Sorry I am not very technical how do I find out what kind of motherboard I have?

[Computer_Commando]

What is the make & model number of the computer?

[Davda]

    I think my computer is a Gateway 507 gr

No such model listed.  If you want accurate assistance, give precise information.

    I'm pretty sure thats what the model number is. It's a pretty old computer so it may not show up on the gateway computer.
when I googled 507GR it came up with numerous results.

Is it from the power supply you mean green light blinking? If yes, try removing all connecting source inside from the power supply to motherboard, drives. Remove also CMOS battery and wait for about 5 minutes. Reconnect and before plugging in, press power button for about 15 seconds. Then plugged in from power source and power on your tower. Make sure all connections are fully seated and nothing amiss. If no changes, then try another PSU.

This looks like it:  http://support.gateway.com/s/PC/R/4658/4658nv.shtml
Pentium 4-530, still very useable, same as one of mine.

The blinking green light on the back & on the motherboard indicates the power supply is not operating properly.  New ones are about $30.  Read the nameplate on the PSU (Power Supply Unit) to get the specs, but any 300W ATX one will be good if you are still using the onboard video, if you are using a PCI-e graphics card, then 500W will be required.  You can't get too big, only the price gets higher.

This one is on sale for $30, if you don't mind sending in the rebate:  http://www.newegg.com/Product/Product.aspx?Item=N82E16817153113

   Thank you very much for the replies. But jason I have one question. When I disconnect all the things do I risk ESD?

[jason2074]

You only need to unplugged from power source then touch metal casing of your tower. But most would recommend using anti static wrist strap for precautionary measure and also avoid causing static charge when touching internal components and damaging them. http://www.computerhope.com/esd.htm

    No success. Although when I opened up the case I saw that there was a red wide wire that was not connected only to the mother board but nothing else. Could this be the problem?

Sounds like a SATA cable. If your hard drive or DVD drive is a SATA drive, it should be connected to that.

... there was a red wide wire that was not connected only to the mother board but nothing else...

This statement makes no sense to me.  Please rephrase.
