I have an Acer Aspire E700 PC connected to an HP w2216 Monitor.
It's been working okay for some time but suddenly the MS Vista picture moved over to the right leaving an 80 mm. blank gap on the left.
This is now permanent. It cannot be fixed using the Monitor controls or the Software. When the computer is first turned on the whole screen is filled but shrinks as soon as Vista kicks in. Could this be a Display Driver problem? Any help would be appreciated.

you could have a bad video chip. Failure to POST could mean anything, but most times it's a video chip. Still, you can try re-seating your ram chips, re-seating your CPU, and re-seating the add-on cards that you may have.
Hook a spare monitor to the video output usually on the back, if picture okay! the inverter board just below the laptop screen is defective, "more than likely" or the backlight behind the display is faulty, but if both show the same symptom it is the video graphics card normally built into the motherboard.
You may have more problems than just he power supply from when the old power supply went out. The mainboard could be bad.
Make sure it's unplugged from power from the wall, then check that the memory is seated correctly. Check for anything else that may be out of place or not fully connected.
There are also different beep codes for different errors. They've mostly been standardized, but may vary by mainboard as well. Here's a link to common POST beep codes and their meanings: Computer POST and beep codes
If you get a post screen with Acer written on it at startup, and the screen turns off when loading the system (Windows or Linux), then you need to reinstall the system using an external USB cd unit and the recovery disk that was provided with your Acer.
If instead the display has no screen at all , try connecting an external monitor to test the laptop.
If you get picture on external monitor, then the Aspire One has a faulty LCD ribbon cable or a faulty LCD display or inverter.
If you get no picture on external screen , then you have a faulty motherboard, possibly faulty video chipset on motherboard.
In any case check your Acer One warranty, all the faults listed are covered by Acer warranty for one year. Contact Acer at the number listed on documentation to have the computer repaired.
when problems occures with monitor is always with picture tube but some time less brightness is also reason for black screen
check brightness of your system i think it should be on maximum level and brightness is perfact so i said problem with picture tube. may be picture tube is gone...
Does your BIOS POST runs then you might be having a Disk Booting Problem, If you dont see your BIOS POST Screen, then check if you can hear any beep sounds, If you hear beep sounds check the ram whether it is properly inserted in the ram slot or the ram might be faulty.(You may have to change the Ram). If you dont hear any beep, check whether the buzzer(Speaker in the CPU) is working, If buzzers were working fine before, then you might be having problems with your mother board or processor. If you know how to work on such problem try reinstalling the processor, ram etc in the cpu . Otherwise call a service engineer to have the job done.
