ugg clearance uk Dell Optiplex GX620 Black Screen Issue

Ok guys im stumpped on this one. I’ve been working on this computer at work and it keeps having this issue where at seemingly random times when changing any video setting the screen will go black and the only way to recover is to reboot the system in VGA mode, and step up the resolution one setting at a time, which only works sometimes because it has to shut off the monitor between steps (explained below).

The computer seems to always show video when in 640×480 mode but when changing to anything higher or making any changes that require the computer to shut off the monitor it is hit or miss. If it works it works and if not the monitor goes into sleep mode like you turned off the computer (this includes during boot when changing from POST screen resolution to windows desktop)

My New crap video card was having same types of symtoms. I got a different brand of video card and it fixed it.

1. Try reinstalling new drivers. Use drivercleaner etc.

2. Reset the cmos on your mb see if that helps etc.

3. Try different bios settings.

4. Try changing your Hertz Lower or higher on your monitor. My monitor will go all black and say some stuff when its out of hertz for the monitor.

5. New laptop mb. ? Other then that, i got no clue.

About my spelling, If you say anything about it im gonna hunt your nerdy english aniel retentive arrrssse down and beat the elcrapo right out of you!
