Question about PC Desktops

1 Answer

Using my emachine T6542. Went to get a cup of coffee. Took me 15 minutes. When I return, no more signal in my monitor. All I hear are fans of the CPU and power supply. Opened the PC box. No loose parts. What could be the problem with that?

    Thanks for the solution you have given. But, that was not the case. I do that all the time. This last time, i used it, when I came back, can't use it anymore. This happened more than a week ago. Tried turning my computer on many times. No monitor signal, usb led lights are off, even the keyboard light is off. All I could see and hear are fans of the power supply and the CPU. Could it be my motherboard? that gave up. I need all the help I could get. This emachine is less than 2 years since I bought it. No more warranty. Not ready to buy a new one. I go online using my friends' connections to get help. THANKS

    I have this same emachine and it just started doing the same thing when I try to start it up - the fans run at high speed and the DVD drive seems to function (light blinks & tray functions), but nothing else works and the monitor has no signal. I cleaned out all the dust, removed the memory card and power supply to check for loose connections, but that didn't have any effect. After trying multiple times, I managed to power it up once, ran a full virus scan and got all my files onto a CD-ROM.Then it wouldn't restart, even when I tried a Windows "soft" restart.

    I noticed on another forum, that one user commented on how hot this model was running internally and claimed that it would probably fry the motherboard at that temperature. Could that be what is happening? There was a lot of dust in my vents, which could have exacerbated this condition.

Hello,
This could be a power saving issue. The computer may be set to go into power saving. When you come back and find your computer in this state, shake your mouse and see if it brings it back. If it doesn't, then press the power button of the CPU once and it should come on right where you left it.

If none of this helps, then your computer may be having another problem. Let me know

Thanks,
Lolita

Computer turns on, but screen says no signal


Computers send out a video signal.

If the monitor isn't receiving a video signal, you get No Signal on the monitor.

First thing to check is the monitor cable. Cable is used on another working computer to verify, or known working computer's monitor cable, is used in place of it.

I believe we can skip that.
Why?

eMachines are budget computers. Designed to save the consumer money, and give the consumer a decent computer.
Problem is low cost of computer, is due to certain hardware components inside the computer, are of low quality.

The Power Supply being one.
Dirty computer inside, also leads to early Power Supply demise.

You can;
1) Test the Power Supply with a multimeter. If you do not have access to one, economical models sell for around $5 to $12.
You will be testing three main voltages;
3.3 Volts, 5 Volts, and 12 Volts. All are DC Voltage.
In comparison two D cell flashlight batteries store 3 Volts DC.

[ Power Supply's are converters. They convert the dangerous high AC voltage (100 to 240. Depends on what country you're in), to the above low DC Voltages ]

Or do you have a KNOWN to be good, Compatible power supply; you can borrow from a working computer?

(I posted this one time, and the person posted back they had borrowed a Power Supply, from their aunt. Computer sat in the garage unused. When finished they returned the Power Supply. Put it back in the computer. Then went, and bought a new one )

Before performing the above, would like you to try this;

Unplug the computer from power. Press, and hold the Power On button in, for 10 seconds. Let go.
Do this same procedure two more times.
Continue also, until the Power On light doesn't briefly flash anymore.

Now plug the computer back into power. WAIT 1 minute.
Turn the computer on. The processor fan, computer case fan/s, and Power Supply fan; should race, (High idle speed), for a few seconds; then slow down. Let's see.

For additional questions please post in a Comment.

Also post the model number of the eMachines. Some examples, T1090, W3653, etc.

No screen


MOST likely the monitor is bad if you don't hear any beeps when booting up.

If you unplug the monitor the screen should say NO SIGNAL

My monitor suddenly lost signal and hasn't returned


do you mean the processor fan that is located near on the left top corner on the motherboard? if that stopped working then turn of your pc immediately. probably the cpu overheated. if that fan does not work replace it immediately as it will burn the cpu.

My dads e-machine 3630 is only a year old and has been used very little. Yesterday when he turned it on you could hear the fan running really loud and the monitor briefly flashed "no signal" but then went...


Are you sure it was the fan? Was there any type of clicking noise present? If so it points to your HDD... Also check to see if your video card is fully seated in its slot.
