E510 Goes Black When Desktop Comes Up
I have a Dell E510 that has been running Windows 7 Ultimate fine for a
while. I put it on the shelf in October 2015, and brought it back out last night. I forgot the password, so I used the Dell supplied OS disk, went into repair, and used the sethc.exe method to reset the password: http://www.howtogeek.com/96630/how-t...otten-windows- password-the-easy-way/ This worked, but now the monitor power light goes from green to orange (power saving mode), the keyboard lights go out, and the mouse light goes out. I can hear the power supply fan still going. Thinking it may have been a problem with the discrete video card, I removed it and set to use the onboard video. Same problem. The problem also exists in all Safe Modes. Funny, though, as long as I don't enter my new password, the thing stays on. That is, it will sit there forever asking me to enter my password, but as soon as I do, everything goes out either immediately after hitting Enter, or a few seconds after the desktop comes up. I've tried a different monitor, too, but same problem. Any ideas? TIA |

I took a video of it with my cell phone, and watched the particular two frames that had the message: "Cannot Display This Video Mode Optimum Resolution 1200 x 1024 68mHz" How in the world do I change this if I can't get into the desktop? |

Can you start up the E510 in safe mode (F8)? Once in safe mode, change the resolution there. Apparently it was originally used with a different monitor. I usually remove Windows login passwords with this: http://pogostick.net/~pnh/ntpasswd/ You can download and run it from a CD (obsolete), floppy (even more onsolete) or a bootable flash stick. Download the latest ISO and use RUFUS or YUMI to set up the flash stick. |

On an LCD monitor, the OSD is supposed to display "Out of Range" when the resolution or refresh is wrong. A typical "problem" is the Refresh getting set to 150Hz by a corruption of some kind. The normal LCD refresh is 60Hz. ******* Safe Mode gets you in (F8), but I don't know what to do when you get there :-( http://www.sevenforums.com/tutorials...safe-mode.html The thing is, there are a couple different places in the Registry where display resolutions are held, and I don't have a good technical reference web page to offer you on the topic. Even if you uninstall a video driver, the resolution info is not removed or corrected. So trying a video driver won't help. But it's the only obvious option to try. Paul |

Paul On this particular Dell model: F2 is Safe Mode, etc F12 is Setup .. I was able to get into Safe Mode, and the desktop came up, I right clicked on an empty spot on the desktop and left clicked Resolution, and the Resolution applet came up. I was able to set to 1280 x 1024, default refresh. I was able to roam all over, and the desk worked fine. But, when I restarted, it went dark at the desktop. Back to Safe Mode, I was able to see the proper resolution was still active. Think I'm ready to System Restore to July 2015. |

There is supposed to be some time limit on them. Since the machine has been sitting in storage, there is probably no harm done by using the last restore point it made before sitting on the shelf. And using System Restore, is a good way of getting a non-corrupted copy of the Registry. That's one of the benefits of System Restore points. Now, one problem is, if you do it from Safe Mode, you cannot undo it again. If you want a "safety solution", use your Macrium Reflect CD and back up the drive to an external drive. If you don't like what the System Restore did to the machine from Safe Mode, you may need to reload from the backup. Not that things can get any worse than they are right now... Personally, I'd rather fix the Registry, except I wasn't able to find any decent documentation on the registry locations. Paul |

Do you know what is the maximum resolution of your LCD monitor? That should also be its native resolution and what you you want to use. If Windows' safe mode lets you log in okay, disable all startup programs and test booting Windows into normal mode and logging in. You could use msconfig.exe to disable startup programs. You can select them one by one or just use the option to start up cleanly. Could be you have a startup program causing the problem. |

The normal LCD refresh is 60Hz. ******* I thought the idea was to enter safe mode and select the lowest res allowed. Then boot back into normal mode which should also load that low res and then up it to what you want, e.g. set it to 800x600 in safe mode and assuming you then get a screen under normal mode try upping res until it stops working. If it's not what you expect at that point you can diagnose further. I've had to do that a few times years ago mucking with video cards and monitors before hardware worked itself out. You might also try deleting the video driver under Device manager in safe mode and see what happens when it redetects video card when booted normally. Yep, those are good ideas. |
