Optiplex 740 Computer Won't Start


1. Verify it is plugged in.
2. Press power button.
- does your power supply have a switch on it? Look for a black rocker switch
3. Do you hear a beep?
4. If you hear a loud continuos beep, power down the Machine and unplug it.
5. Hold power button while PC is off, it may come on for a second.. This is called "bleeding the capacitors"
6. Open the side of the case.
7. Find the RAM (random access memory), they are long rectangles about 6inches by 1inch. Remove one.
8. Plug in power cable and start computer with one stick of RAM, problem solved, you have bad ram.
9. Remove all PCI cards, and cards that are in the back of the computer. Remove them from the white slots, there is a small screw on the side near the back of the computer to unscrew, you will need to remove a small black door that holds the cards in place. BE SURE power cable is unplugged.
10. Power the computer on. If your computer turns on, you win.
Power down Machine and add cards until it doesn't work, the card you insert and causes the computer to not boot is the card that is shorting out.
11. When you plug in the computer are there any lights on the mother board. If so at least your power supply is working.
12. No light? You need a new power supply. There are 4 screws on the outside of the case where you were plugging and Un plugging the power cable. Remove screws and remove power supply, you will need to disconnect all connections. Type any and all numbers into an Amazon search and spend the $25, Amazon is safe.
13. If you are "posting" entering the BIOS (basic input output system) you're not in bad shape. This means your power supply is working and rh motherboard is working.
14. Restart computer and keep pressing f2, arrow over to advanced, then down to "boot options" make sure your hard drive is on top of the list" if it is not, move it there.
15. press F10 to exit and save changes.
16. If USB is first in the list and you have a USB stick in your machine it will try to boot from it! Take it the USB stick!
17. Press F8 to run safe mode.
18. See how it boots or if it does.
19 restart and try to boot
20. May need to run repair
21. Google search how to get a repair disk for your operating system.

My asus k60ij won't boot up when i press the power button


Glad to HELP YOU!

If your machine doesn't boot by pressing the POWER button it means that your computer doesn't have power to start up.
So probably the Power Supply Unit/Power Unit is defective and it has to be replaced.
If you are computer savvy you might check it and you might replace it by yourself. But if you are not ask the help of a technician. These Asus machines are sometimes very fragile and easy to be broken.


Hope it helps you!

When the computer on/off button is pressed , the CPU fan and tower exhaust fans start running, the blue light around the power button does not light and the boot up process goes no further. Fans continue...


A) When you hold a Power On button, (Switch actually), in for a count of 10 seconds, it turns the computer off.

(There is a Power On switch, located behind the plastic Power On button. Usually, the Power On switch snaps into the housing of the plastic Power On button.

Example of a typical ATX Power On switch,

http://www.directron.com/atxswitch.html

The Power On switch turns the Power Supply on.

Old computers had a metal rod, that when the Power On button was depressed, the button pushed against the metal rod, which in turn pressed against a power switch located inside the Power Supply.

The design after that, was a power switch located in the Front Panel. (Plastic front of the computer) A large cable, (Wire) ran from the switch to the Power Supply.

Now there is the Soft Power On feature. (PS_ON)

The Power On switch is a small Momentary Contact Switch. Pressing it closes a circuit. The Soft Power On circuit.

When a power supply is plugged into power, there is a constant 5 Volts (DC) present.
This is the 5 Volt Standby.

Closing the Soft Power On circuit, redirects the 5 Volt Standby power to a circuit within the Power Supply.
This in turn 'excites' the Power Supply, and turns the Power Supply on.

Sorry to be windy, but I wanted you to know how the Soft Power On feature works )

eMachines are a budget computer. As such they save the consumer money.
However in order to do this, the manufacturer will install low quality parts, in some areas of the computer.

One such part is the Power Supply.

1) ALL the LED lights combined use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts

3) A typical Processor can use 51 to 125 Watts.
Depends on what Processor it is.
(Had you stated the Model Number I could have told you)

Enough power to spin fans, but not enough to spin fans, AND turn the Processor on.

Do you have access to another computer that is unused, but has a Known to be good, Compatible power supply?
It could be used for a test unit.

Tell me the Series, and Model Number of your eMachines, and I'll tell you what Wattage it should have, and what power cables, for the Power Supply.

(Some examples of Series, and Model Numbers, T1090, E4264, W2925, and so on. The T, E, and W are a few examples of the Series letter.
The numbers following the Series letter, is the Model Number)

If you wish I can direct you in removing the Power Supply, and installing the test unit. (And/Or a new Power Supply)

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.

Beeps 2 times & a warbling noise when trying to boot up - unplugging power lead & pressing ON/Off button & reconnecting power lead starts up OK - but it can be OK for several days & then repeats the p


The Cause of Problem:

The Power Buttons electrical circle sometimes just braked it by one of sensors and the result is the 2 beeps and Power Supply is in protected mode error.

The whole computer is turn off but the power button is turn on and this is the nub of the matter. Because if you want turn on the computer you can't because already turn on but just the Power button and you can't do anything.

The solution:
You need just change the Power Supply and don't do anything just the power cable put into the Power Supply after turn off computer.
Finaly change back the Power Supply.

Tower problems


You may need to replace the cmos battery, its a cr2032 3v button cell
Make sure all your expansion cards and memory are reseated.
Make sure all cables are reseated.
your power supply could be bad

If that doesn't work try this


Here is my fix for the dell dimension 4400 amber light problem. It works!
replace cmos battery.
then unplug power cord form wall about 5-10 secs.
then plug it back in, wait 5 secs.
If amber light comes on, press and hold power button until it goes out.

(with light out, press and hold power button while amber light comes on and goes off again holding power button 2-3 secs after light goes out.) repeat whats in parenthesis until computer turns on
it should only take about 6, 7 tries.

After the computer boots, you may want to setup cmos or boot into windows.
After you shutdown, unplug power cord for 5-10 secs then plug it back in.
Press and hold the power button, computer should come on.
I found that's the only way to turn on the computer.
If you shutdown and don't unplug power cord the computer may not boot, mine didn't.
Strange I'd say
