Acer Aspire E380 - Monitor Does Not Transmit Signal

Hello! Has anyone else experienced this kind of trouble? It seems that the computer itself (CPU) properly powers up, and the monitor and all its attaching cables have been verified as functional, via connection with another computer.

Some history that might be relevant: the computer was manufactured 12/21/2006 and was originally outfitted with Windows Vista Home Premium. My father erased that OS and downgraded it to XP. Some time later the computer stopped sending signals to the monitor. It has been over a year now since the whole setup quit functioning.

Any clues on where to start the trouble-shooting process?

Many thanks in advance!

Tried Reseating The Video Card?

In reply to: Acer Aspire E380 - Monitor Does Not Transmit Signal

.. A lot of simple things to start with as long as you've verified the monitor is actually functioning. Although you've confirmed that the monitor was functioning correctly, have you tried swapping in a known good monitor to the tower just to make sure it's not a monitor issue?

I would still try swapping in a different video connection cable just to be sure... Open the case and if it's a standard video card, make sure the card is seated correctly by removing it, then putting back in the slot. Check to make sure any secondary power cables are connected to the card, if there are any.,,, or if it's an integrated video device, you may want to swap in a known good video card..

Hope this helps.

Will Do

In reply to: Tried Reseating The Video Card?

Thanks for your extremely swift and informative response.

I'm looking into aquiring a known good monitor and video connection cable. Hopefully the issue is that simple. I'm prepared to open the case up to investigate the video card if I need to, but, for fear of my slippery fingers and more slippery computer knowledge, I'm going to avoid that if I can.

You may see me back on this thread quite soon!

Did he install ALL of the drivers when he did the OS change? Sounds as if you are missing the video drivers.

How to check?

In reply to: Monitor/video

Thanks for your reply!

Unfortunately, I'm not sure that he'll remember what he did, but I'll interrogate him about it when I get the chance.

In the meantime, how would I solve that problem/make sure the appropriate drivers are installed if I can't see anything that's going on in the computer via moniter output?

Have you tried booting into Safe Mode?

In reply to: How to check?

Doing so bypasses specific video drivers and makes use of the generic
VGA driver for the video chipset.

Can you see ANYTHING on the monitor as the computer begins booting (can you access the BIOS)? If the answer is no to both it is most likely that the video card itself is bad.

Hi Edward, thank you for your help! The monitor shows absolutely nothing when it is connected to the Acer tower, so I presume there's a problem with the video card itself. Considering I'd never heard of a "video card" before this episode, I think I'm in for the long haul. I'll crack the tower open for a peek. Now, the only trouble is being able to recognize what looks right vs. what needs fixing.

It seems from the symptoms that it could be a number of things -- if you see nothing ever on the monitor, not even the power on self test, then it could be video, or could be something else (main board, RAM, CPU, power-supply).

See if the monitor is working on a diff computer (laptop or desktop).
and/or see if a diff monitor works on the computer.

Trouble-shooting is a bunch of "not this" until you find what's the culprit.
