Monitor just went blank, no power light.


Was the PC running, and then shut down? Or, did it never start in the first place?
It sounds like it could be one of many things. Sometimes if the processor fan has failed, the computer will start up, and then shut down. Also, bad memory can cause the PC to shut down.

Problm with viewsonic va712b


sounds like the operating mode is at a frequency or refresh rate that is outside the viewsonic operating specifications when in normal mode. possible solution: in safe mode access control panel, system, devices (hardware) and look for display. do a right click and uninstall. repeat right click and "scan for hardware changes". That might reset the monitor operating modes but it also gives you a chance to reinstall drivers. If this does not work, try other monitor crt/lcd to see what happens.

No video output from my computer.


Are you using an ON-board graphics adapter or a separate VIDEO CARD? Some motherboards lets you set the video output to "DISABLE ONBOARD GRAPHICS" if you have installed a video card (BIOS). You may have plugged the monitor cable to the onboard D-sub connection instead of using the Video Card D-sub connector.

Normally a flashing green power light means the input it receives from the video output is too much. You may have set the resolution too high or the bit depth too high. Consult the monitor manual on the rates it can handle. To be safe, try starting the computer on safe mode just to check if it is indeed the problem. If it boots properly and you can see your desktop, then there's a chance that the setting was too much for the monitor to handle.

Hope this gives you an idea.

Monitor Goes Black


Try to start in safe mode and check if you can change some of the video settings (resolution, refresh rate, etc). Maybe one of these settings is such that the monitor cannot handle properly. To get into Safe Mode, press F8 as soon as you see the Gateway logo on the screen while booting the PC.

Blank Screen..Will not power off


The flash light test only works with lcd monitor as they have back lights. Double check the connections again, also, if you can borrow a monitor try it on your pc, it may be your graphics driver needs to be uninstalled and re-installed, but you will need a monitor to see.
