Blank screen with full screen dos window
Hi,
I recently uninstalled a problematic anti-virus program on a pc, ran adaware, spybot s&d, ccleaner etc and did a defrag. Since then I've been unable to get open a full screen dos prompt, I just get a blank screen. None of my dos applications run in full screen either, It's as if the program is there (as if I type "exit" at the dos prompt the window closes) but I can't see anything. I can run in windowed mode without any problems. Can anyone suggest what might have caused this? Can it be rectified fairly easily without losing any existing data? I really appreciate any help, thanks. |

Blank screen with full screen dos window
Well, let us look at the Properties of your Windows DOS box...
"START, Programs, MS-DOS prompt". Don't click it. R-Clk it & select Properties. Here are my settings. (1) General tab: Size is 1474 bytes. Attributes: Only Archive is checked. (2) Program tab: Name: MS-DOS Prompt Cmd line: C:\WINDOWS\COMMAND.COM Working: Blank Batch file: Doskey Shortcut Key: None Run: Normal window Close on exit: Checked Advanced button: Only "Suggest MS-DOS mode as necessary" is checked. (3) Font tab: "Both font types" is bolted. Font size: Auto (4) Memory tab: Everything is Auto; everything else is checked. Details button: Complains about "NoEMS". (5) Screen tab: Window is bolted. Initial size is 50 lines. Everything else is checked. (6) Miscellaneous tab: QuickEdit, Exclusive mode, & Always suspend are unchecked. Everything else is checked. Idle sensitivity slider is in the middle. If that is all well, then we must check the Properties of both your Command.com. COMMAND.COM Type: MS-DOS Application Location: C:\WINDOWS & C:\ Size: 93,890 bytes Created: Friday, April 23, 1999 10:22:00 PM & (unknown) Modified: Friday, April 23, 1999 10:22:00 PM ....the one in C:\ is "Created: unknown". However, I'm not worried, because many system files are like that. In various threads here, wise ones have said to keep both. The important thing is that both have the same Size & Mod date. If one does not, then it could be a virus, & an investigation must begin. -- Thanks or Good Luck, There may be humor in this post, and, Naturally, you will not sue, should things get worse after this, PCR "SlackerAPM" wrote in message ... | Hi, | | I recently uninstalled a problematic anti-virus program on a pc, ran | adaware, spybot s&d, ccleaner etc and did a defrag.

Blank screen with full screen dos window
Thanks for your help,
It seems as if it is a display problem. When I booted into safe mode there were 20+ display adapters and 3 different monitors. However, I seem to have made a bit of a big mistake. I removed all of these and restarted. I now cannot get into Windows, it boots as far as displaying the Windows 98 screen then the screen just goes blank. I've tried restarting in safe mode where it tells me I have to run in 640 x 480 mode with 16 colours. No display adapter or monitor is displayed either. Is there any way I can select a display adapter before booting into windows? Or make it pick one by default? Is this what is causing my blank screen problems?

Terhune used to say it could be trouble to remove the Video Adapter in Device Manager. Those instructions I posted didn't actually involve the Device Manager remove button for it. But I can't blame you doing it with 20+ in there! Did you FIRST do what I quoted of Starbuck in Normal Mode-- "change the adapter to 'Standard Display Adapter (VGA)' and restart the system". That could make a difference. (1) Hopefully, a Registry /Restore will get you back to where you were. (2) Then, in Normal Mode, follow my previous instructions to note which monitor & which video adapter appear to be installed-- at the Device Manager, Properties, Driver tab, Update Driver button. However, under the circumstances, I'm not sure it knows! (3) Switch to "Standard Display Adapter (VGA)", & boot to Normal Mode. This may somehow make the difference for a better outcome. (4) Boot to Safe Mode, & do the device manager removes again, if you've still got that many showing. (5) Boot to Normal Mode. Which show up as installed? Is all well? I'm not a big proponent of a "/Restore", but sometimes it can do amazing things. And this sounds like a job for it. Before trying it, copy your current Registry backup files to a new folder. (a) Boot to DOS (hold CTRL as you boot for the Startup Menu, & select "Command Prompt Only") (b) DIR C:\Windows\Sysbckup\RB???.cab /od Shows you the current backups sorted by date. (c) MD C:\RegBckup This makes a new folder named RegBckup. (d) COPY C:\Windows\Sysbckup\RB???.cab C:\RegBckup This copies your Registry backups to the new folder, because the originals will change as you do the following... (e) SCANREG /Restore It will offer five, one for each of the last five separate days you booted successfully. Start with the one of the day the problem began, as these backups of the entire Registry (& System.ini & Win.ini) are done at boot, not at shut down. CAVEAT: A /Restore restores settings only. If there was a file change (other than to System.ini & Win.ini), those cannot be undone this way. That could be a problem, especially if there was a hardware change or large un/in-stall since the backup was made. Also, a large settings change, such as adding/removing a User Profile, is likely best undone a different way. Finally, some apps may keep a small database in the Registry. I do believe Explorer itself may keep it's list of blocked sites there. | I've tried restarting | in safe mode where it tells me I have to run in 640 x 480 mode with 16 | colours.

In safe mode, access the video display setup and change the setting to
640x480 (it will already be set like that) and select OK. This should re-set the setting for normal mode and allow you to boot so you can install the proper driver for your card. -- Jeff Richards MS MVP (Windows - Shell/User) "SlackerAPM" wrote in message ...
