Want to put a extra screen

Have the same problem and i solved it after 1 month tries
the problem was in NVIDIA Graphic card
the solution was by by heating the NVIDIA Graphic card for 5 min or more

The usual cause of screen flicker is a lack of power getting to the graphics card. The best way to check this is to remove another component to see if the flicker stops. If it does stop you need to upgrade the power supply.

Upgrading the power supply is a simple job. Let me know if you need more information on replacing the power supply.

sounds as if your extra screen is on still....

Hi Neil,
Any screen will do.
It is now worth a resolution of 1680*1050 (perhaps Fujitsu)
I recommend using a slot card or change the one installed with one with 2 outputs (eventually HDMI or HDVI.

Monitors need to be plugged to ports called VGA (blue) or HDMI, DVI (white)
If you instead have decided to use the USB you need also to find a USB adapter like this: http://i638.photobucket.com/albums/uu110/z-Traxx/NewerTech-USB-Video-Display-Adapter.jpg

With Windows XP you can hav the possibility to mirror or extend the Video going under Right Clik on Desktop/Properties/Settings and select here the 1 or 2 monitors.

Or you guys could stop being ******* RETARDS and learn that Acer 6930G actually has second drive bay in lower left corner for installing secondary hdd.

You will need to get two(three counting connector) extra parts from Acer though: new cover (old one doesn't fit, metal mounting plate and connector.

u have to remove extra memory and put that original then power if dosent work try to reset bos battery

make sure you pc is turned off before you start. To add additional internal hard drive you will need to get SATA hard drive. when you open up your pc there will be a slot to put it in. on the new hard drive there will a display with shows you how to make that hard drive a slave. move the little thing to the right place and plug it in. when you restart it should read it .

2 possible reasons :

1 - Video controller has failed - (Unlikely as you would normally be left with a plain black screen)
2 - Connector has come loose from main board (very possible due to the way in which they are generally located)

There are no extra port to put new rams

You have to use the same ram slot to use a new large ram

no u dont need look @ the bios>if u insert it properly that should display it if it is not then teh card is bad>or the slot on the board if the solt works with the other card then there is no issue with the slot so replace it rate me solved if its help full thx
