Hardwre acceleration moved to "none" -blanked out my Screen!

by cobwln / February 18, 2008 3:33 AM PST

After I sccessfully restored my Dimension B110, [80 Gb HD, 512 RAM, KOGi 15" LCD monitor, CD/DVD RW]. The only problem was the monitor's resolution defaulted to 640x 480 with 16 colors.
I tried Control Panel, Display properties, but only shows ?Default Monitor? others are blanked out. Many help screens later, I tried one other possible suggestion: Display properties, Advanced, Troubleshoot, Hardware Acceleration, and I moved the level of acceleration/ performance ALL THE WAY TO THE LEFT "NONE" and restarted the system. After the restart, the monitor screen just went blank. It's been blank since, even if I tried reboot to [1] a safe mode (unfortunately I did not create a Windows restore point before I did all these); [2]connected another LCD high res monitor (ViewSonic 17"), and [3]rebooted using the Dell reinstallation operating CD Rom on the C Drive.
I appreciate anyone's help.

Tried to reboot, F2 (Set up),but nothing. After reboot, few seconds of Microsoft Windows screen, then blank screen. Used another high resolution LCD monitor, but still blank screen after reboot.

LAST KNOWN GOOD CONFIGURATION

Which does not rely on System Restore.

Screen blank after adjusting the hardware acceleration card

In reply to: Try...

I tried that route but the screen remained blank. I know everything is working fine except the screen monitor because the installed magicjack voip is working. (As I mentioned earlier, I tried connecting another LCD monitor but the screen remains blank after the reboot).

1. Should I just replace the video or graphics card?
2. It's interesting the screen will show the Windows logo upon reboot before it goes blank.

Thanks for your help.

If safe mode shows no screen

You have to test it with another display and display card. I usually reach for my Linux CD for another test.

It's not the video acceleration here since Safe Mode doesn't honor that.

I don't have a Linux CD so I'll try to download one and see if that'll work.
If not, on to Fry's I go to get a new display card. I hope I can use my ViewSonic monitor on a new display card.
Thanks for your help and I'll update you on what happens.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
