Take the ram back out of the computer that you just installed and see if you have the same problem. If you do, a board or plug must have came loose when you were inside the unit. If the problem clears up, the ram you are trying to use is bad or not compatible with your computer. All ram is not alike. Good Luck

My psu will not stop beeping. I have an enermax EIN 720 AWT

the beeps are post during post the very first work is done by the ram,all the memory in the ram is first transferred to the hard disk,and remains active untill turned off.

make sure that your RAM is securely seated

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect your 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 they could be faulty

a computer needs its connections to continue its cycle and to have and end to function
obvisously the beeps are windows searching for some hardware it could be RAM cd/dvd hard drive or motherboard all of these must have secure connections for the computer to work
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure make sure the connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error
hope this helps

lizgoodwi537 I would like you to take the Ram Memory module/s out ('Stick'), and clean the gold plated contact pins on the bottom.

Typical example of a ram memory module showing the gold plated contact pins,

(You can click on the photo to enlarge. You can enlarge twice)

Computer on a table, computer unplugged from power, computer case open, Observe Anti-Static Precautions.

Use a pencil eraser to clean the contact pins. Both sides of the ram memory module have contact pins.
If you are Not using a solid pencil eraser, and the eraser on the end of a pencil, refrain from letting the metal band touch the contact pins.

Doesn't take much pressure. Just rub the eraser up, and down on each contact pin.
When you are finished it may look as though you have done nothing at all. The contact pin may not be much brighter than when you started.

It's okay I assure you that you have made a difference.
The gold plated contact pins corrode after a while from sitting. Doesn't take much corrosion to make a bad contact.

When you are finished cleaning, use air to remove the eraser dust. You can use a can of compressed air for computers, if available, or air pressure from your mouth will be sufficient.
Reinstall the ram memory module/s.

Close the computer case, plug the computer into power.
WAIT 1 minute, then turn the computer on.

Let's start with this easy procedure first.
Past this point we will be looking for bad Electrolytic Capacitors on the motherboard, and then into the Power Supply.

Exactly how far does your computer get before it restarts? there is normally a short beep during the startup phase, do you hear the short beep, or is it a long beep or a combination of different beeps?
I am not saying that it cannot be the power supply but usually problems of this sort are a faulty graphic card or faulty RAM, worst case senario is a faulty motherboard. The first two you can test by adding an extra graphic card or replacing the RAM (or taking one out and then the other if you have more than one RAM) - BE AWARE that you can damage your computer or the RAM itself if you touch the wrong things and you are have a static charge.

When i press the on switch the computer light turn red color and have a beep sound.

1 or 2 beeps is normal when turning on, for most mobo's. Check the motherboard owners manual for beep errors, for example 3 beeps might be a graphics card error, 4 keyboard error, or CPU or memory. it's in the manual for the specific motherboard. You can get it from the manufacturer's website. I can not supply a link to get you the online manual because you didn't specify what kind of motherboard you are using. Does it still boot? Do you see the BIOS on screen? Any error messages? When you press the power button your computer normally should beep once or twice and then performs a POST... Power-On-Self-Test. and this is when you get any error beeps. It could be something simple like forgot to hook up the monitor, to CPU or memory is loose, or memory is not compatible if you upgraded the memory.

Computer not powering up / no light at hard drive.. but power to machine

Ok...since there are lights..then it's most likely, not your power supply.'
We need a few questions answered so we can narrow it down to what it could be.

1. What operating system are you running, harddrive, ram, some computer specifications would help?
2. What was being done last, when the computer went could possibly be a virus, so we need to find out if a file was opened up, or an email, things like that.....was there something any beeps beep when the computer starts up>

Let me know these things and we'll narrow it down to something solvable..

Re-seat the video card and memory first,
if it continues to beep count the beeps 3 long ,3 short .etc
they mean a code.
