I have a Acer moniter too. Seems like you have a loose VGA cable or not enough power going into the video card

Acer aspire 5742Z wireless adapter Atheros AR5B97 intermittent fault loses all local wireless signals. Sometimes can I recover after diagnosing problem - sometimes need to reboot to recover. ??


CONTINUAL DISCONNECTION OF WIRELESS CONNECTION
There are a few things that can cause you to lose wireless connection with your wireless router. 1. Weak signal strength, check the signal strength on your wireless card. If it is weak move the wireless router away from brick or concrete walls and if possible locate the wireless router higher up. 2. Have you secured your wireless router from people near your from unauthorized access? i.e. change the default password, setup encryption use WPA2 or WPA, change the default SSID, and turn off SSID broadcast, and for added protection, enable MAC address filtering which allows only the MAC address/es of your wireless card/s to connect to your wireless router. 3. You could be getting interference from electrical sources such as air conditioners, arc welders, washing machines etc. If so, the power supply to the wireless routers and computers etc should be connected to a surge protection power board, better still connect your computer equipment to an UPS (Uninterrupted Power Supply). 4. Check the channels of the wireless routers and access points in your area and change the broadcast channel on your wireless router to an unused channel or one that is currently used but has the weakest signal strength. This will minimize interference with your wireless router from other wireless routers and access points in your area.

No signal issue


Sounds like you could have a capicitor problem, which is fairly inexpensive to have fixed - before going down that route - If you only connect up the suspect monitor to your PC and disable dual screen using the cables (power and signal) from the one that is working - does the same thing happen? if so then it's definately the monitior and most likely a capicitor.

No Signal


Not all monitors can display the same resolutions. You may have has the Dell monitor set at something the Acer can not handle. Try rebooting and if you can see the Dell startup screen press F8 as soon as it disappears. This will give you the Windows Startup Options menu, which is text and should display on any monitor. Then select VGA MODE, which is the lowest common denominator for graphics. You should be able to see the Windows display at a much lower resolution (ie, larger fonts and icons) than usual until you can reset your graphics properties to work with the new monitor.

Acer LCD Monitor only displays "acer" logo


You are correct, it could be a power surge that has caused it.

Try this..
Unplug the monitor from the wall.
Remove all the video connections at the monitor end.
Wait 10 minutes then plug the monitor back into the wall (do not connect the video leads)

Turn it on and see if it goes past the ACER logo now. If so, replace the video cables and try the computer.
If not, then one of these will apply and a tech will be required..
  1. The internal bios has been corrupted.
  2. The power supply inside the monitor may have issues preventing the video board from starting correctly. This could be as simple as a few failing capacitors.
Number 2 is the most likely cause with an Acer monitor though. Any local tech will be able to correct it fairly cheaply, but phone around for quotes..they can vary a lot.
