Monitor was in standby mode, computer was on. Now it shows no signal and when we try using the menu button (2) it flashes white, black, red, green, blue then a teal color.


the monitor is not receiving a signal from the computer which is why the multi coloured bars are showing. Ensure the lead is connected and is connected to the correct port of your computer. If it is connected correctly then either your graphics card is faulty or the lead, or monitor is

Installed a Graphics Card on my Emachine. Made sure it is in the PCIX slot correctly and seated right. I also installed a Power adapter cable (20 PIN - 24 PIN ATX) to utilize the other 4 pins for use with...


Sounds like there isnt enough power even with the adapters your powersupply cannot give you enough sustained power to run the system if you take the card out does it boot normally? even just disconnecting the power to the card?

Blank sreen.Fan is working. LED indicator is lighted but blinking rapidly.


Try a different monitor. If the second monitor doesn't work disconnect the power and then re-seat the video card. Also, check the RAMs - make sure they're seated as well. Start-up the computer and verify that the hard drive LED is blinking randomly - if it is, more than likely the computer is working properly. Your monitor could be bad as well as the video card. If the VGA port is on the motherboard, then you have an on board graphics card instead of a video card. In that case, the motherboard is bad.

WHEN I BOOT IT UP-NO VIDEO EVERYTHING IS CONNECTED BUT I CAN'T SEE ANYTHING


When a monitor displays No Signal, it is an indication that there is no video signal going to the monitor.

The monitor is working fine.

1) Could be due to a bad monitor cable. They do go bad.

Test would be to take that monitor cable, (If it disconnects), and use it on a known to be working computer.

2) Could be the graphics of the computer.

If the computer has Integrated Graphics, the test would be to install a graphics card, and plug the monitor into it.

[Integrated Graphics is also termed as OnBoard Graphics.
On the motherBoard.

The GPU is the graphics 'engine' of a computer.
Graphics Processing Unit.

It can be soldered directly to the motherboard, (Integrated Graphics), or soldered to a removable graphics card.

http://en.wikipedia.org/wiki/GPU ]

When you install a graphics card, (graphics expansion card), the Integrated Graphics is bypassed.
The monitor plugs into the graphics card, not the motherboard.

Could be wrong, but I'll bet it's the Power Supply.

If this problem directly relates to a Compaq Presario SR1550NX, the computer is 5 years old. (According to my sources)

If the computer isn't cleaned inside, and the Power Supply isn't cleaned inside, on a regular basis as needed, the Power Supply is one hardware component that is sure to fail.

It's the top problem relating to computer failure.

The cooling components for a power supply is it's fan, and Heatsink's that are used inside.

1) http://en.wikipedia.org/wiki/Switched-mode_power_supply

2) http://en.wikipedia.org/wiki/File:ATX_power_supply_interior-1000px_transparent.png

The basic physical makeup of a Heatsink is a flat plate of metal, with tall, thin fins protruding from it.

The flat plate absorbs heat from whatever it is placed against, and the tall, thin fins absorb the heat from the plate.
The fins then radiate the heat away.

If there is a fan used along with a Heatsink, (Such as in the Power Supply, or on a Processor), the fan moves air in-between the fins, and around the fins, helping to carry the heat away.

If dirt, dust, hair, etc. is clogged on the fan blades, center hub, and surrounding cage, the cooling capacity drops tremendously.

The fan cannot move the needed amount of air.

To include on the Heatsink/s inside the Power Supply.

The gunk acts like an insulating blanket, causing the Heatsink to retain the heat, not conduct it away.

Heat = Wasted Energy

The Power Supply tries to keep up with the call for power, and eventually cannot, due to hardware components failing inside.

The Power Supply may seem like it is operating okay.

Lights light, fans spin, and it may sound as though the Harddrive inside is operating.

The Power Supply could have a weak Voltage power rail.

Power Supply's are rated in Wattage.
1) ALL the lights use less than 1 Watt of power.
2) EACH fan uses 2 to 3 Watts.
3) A typical Processor can use anywhere from 51 to 125 Watts.

A bad Power Supply with a weak Voltage power rail, will have enough power to light lights, and maybe spin fans, but not enough power to turn the Processor on.

Harddrive sounds like it is working, because the Platters inside are being spun by the Spindle motor.

http://computer.howstuffworks.com/hard-disk.htm

There is no Processor operating (The 'Brain') to find the boot sector on the Harddrive.
Platters are spinning but the Arms aren't moving the Read/Write heads across the Platters.

In short the computer is not operating.

No video signal to the monitor, because there is no computer operating to send a video signal.
Bad Power Supply.

Emachine 3240 possible power problem?


I would suggest try to swap the power supply out with another known good power supply.

I've seen where even though the light on the motherboard is lit, it is not getting enough power to start the machine up, especially if you have a higher end video card connected to it.

No display and wont boot


A Blinking Amber or Yellow power button means that the power supply is receiving power from the source but is unable to properly distribute it to the components. This can be caused by a defective power supply or a defective motherboard. Power supply is easier and cheaper to replace.

E machine no power


Make sure the RAM is seated, the CPU, any video card and the Power supply is properly connected.

If you power it on, still get no POST (beep at startup from the PC speakers) its time to replace the motherboard.

Emachines 1900+ gets power to the monitor and computer but wont boot


Buy a dianostics card, and find out if its the RAM, CPU, OR Motherboard. (sounds like a ram or CPU problem though) if you have more than one stick of ram in the system, take one out, and power it up, if still not response, to the other stick out, and put the stick you took out the first time, and put it back in.
