Question about Acer Aspire X1200 Desktop PC - Athlon X2 Dual Core 2.5GHz, 4GB DDR2, 320GB, DVDRW, V ...
No Monitor signal and ethernet light on modem not on? What can be the problem?
Please test the power source that the computer is plugged into and confirm it is working with a lamp or something.
If power source is confirmed working and the computer is plugged in and it is turned on and there is still no signal to the monitor and the ethernet lights are not on when the cable is plugged into it. Also check that all cables from the monitor to the computer are connected properly and secure. if the above has been done and still no signal then there are some Possible Causes
1. Mother Board failure (video card on motherboard is defective)
2. Monitor Failure (computer is sending video signal but monitor can not process it)
3. Video Card failure (if the video card is not designed into the motherboard)
Troubleshooting and repair
See if you can get access to another monitor to test the computer with to see if it sends he video signal ok to that monitor. If you can not get access to one then the only option is to get a video card and either you can install it yourself, or have it installed at a repair station.
If you purchase the card and install it yourself most stores will let you return the cards if they do not work or they are not usable. If you do go that route just make sure to ask about return policies prior to trying it.
I would really consider replacing the video card first you can get them from 30.00 and up and there is ony a few screw to remove to install them. Most of the video card manufactures also have tech support for helping people with the installations of the cards.
I would not worry about the lights on the modem or network card until the monitor issue is resolved so you can then see if it is indeed making a connection to the internet.
