Hi - I am having a problem similar to this. I am building a new system (my first). I have a Gateway LCD with a native resolution of 1680x1050, and an nVidia 7950 video card. After installing Windows and the motherboard drivers, I installed the software for my monitor and the drivers for my video card. Everything was fine yesterday. Today, my screen goes blank right after the Windows logo comes up and the monitor says "no signal."

I can boot in Safe Mode. It comes up in 1024x768 with 32 bit color. I changed it to the lowest available, as suggested in the article (800x600 and 16 bit). I said OK when asked if I wanted to keep the settings. But, I still have the same problem when I restart.

I have checked cables inside and out and I don't se any loose ones. I am now considering re-installing Windows, but would like to avoid it. It's strange that it worked yesterday.

Any one have any ideas?

A little more in depth for me, yup, pc boots to Welcome screen for 1/2 sec, and then goes blank. This is not a Nvidia driver problem, I have seen that happen on other machines, removed and applied compatible VGA driver. Does the same thing, so that was not it. I have explored it further, and have found a symptom that may help you diagnose what it is. Allways boots successful to Safe Mode, and stays there as long as I like. Reapplied service pack 2. same problem on reboot, went to scan for viruses and spyware. removed the usual odd virus, and spybot found a fair wack of stuff. nothing special there. The main symptom, i can reproduce now in safe mode, is when I went to install Adaware SE, it gets 1/2 way through its installation, and then it black screens the PC. every time.... It would seem to be something with Windows Installer or something similar, and I can now reproduce this evertime, but am so far no nearer finding the problem. Its definately a service that is broken. The system log under eventviewer does not even get a chance to log an event before it crashes, and the debug and reboot on error options are not ticked.... its a mystery to me so far, but am happy I can reproduce behaviour under safe mode as it goes a long way to narrow down the scope of the problem.

Hi,

I have a Acer laptop with ATI Mobility radeon adapter. I have disabled it in Display Settings. After that screen was working only with 640*480 resolution. I think it was default display adapter. I have foolishly disbled this also in Display settings.

After this system goes blank immediately after windows logo screen. I can hear the login sound on clicking 'enter' key but nothing is displayed.

Even Safe mode or enable VGA mode don't work. I tried all the options in BIOS and F8 menu but nothing works.
Please suggest a solution.

I can't even boot on safe mode

Hey my problem is solved - see below:
If the blank screen is getting displayed after Windows XP logo, but you can hear login sound on the entering the password, it is most probably that your diplay adapters were disabled. Safe Mode or Enable VGA mode should work in this case, but if your default display 'VGASave' itself is disabled then they will not work.

Method-1:In this case try logging in with 'Safe mode with command prompt' (press Press F8 during startup and select this mode). This will most probably enabled even if the display adapters are disabled as it doesn't require any GUI. In the command prompt type "devmgmt.msc" (without quotes) and press Enter. This will open the device manager. In Device manager, goto Display Adapter and enable the available device.

Also VGAsave mode should always be enabled as it is the failsafe display for windows. Open device manager, in View menu select 'Devices by connection' and then select 'show hidden devices' option. Navigate to VGASave and enable it.

If there is no display adapter available and enabling VGASAVE doesn't solve the problem, install new display adapter from a CD. Since command prompt is available, it should not be an issue.

Method-2: If even 'Safe mode with command prompt' is not working try the following process:
1.Login using your user id and passwoerd. Wait atleaset 15 nminutes for windows to be ready. You can not see anything but you can use keyboard to execute the following:
2.Use "Windows+R" to goto Run.
3.Type "devmgmt.msc" (without quotes) and press Enter Key.
4.Press Alt+V and enter the aplhabet "v"
5.Press Alt+V and enter the aplhabet "w"
6.Press tab key and enter the aplhabet "v"
7.Rightclick using keybord, press Down key and then Enter key
8.Press ALT+Y and wait for about 10 minutes.

The above process enabales VGASave. Please give some time gap between each of the commands as you never know which operation takes how much time. Also have some other system near you to simulate the above steps. If this is successful, system would restart and would open with vgasave mode. You can then repair/enable the dipaly adapters. If this doesn't work, again check if 'Safe mode with command prompt' is enabled and follow method 1.
