Hello!
My apologies if this is an old topic. I browsed a few likely-looking threads but did not immediately see what I was looking for.
I have a Dell Inspiron PC which came with the Windows 7 operating system. If more details about my computer are necessary, a bit of direction as to where to find those would be appreciated. I'm good at following directions but I'm by no means a computer wizard.
When I start the computer it starts normally, no weird messages during startup. The logon screen shows up as normal, and I key in my password and tap enter. I see the word "Welcome" as usual, but it seems to be "thinking" much longer than normal before logging me on all the way. Instead of my normal background I see a completely white screen without any icons or taskbar. I can see my cursor though. After a moment or two, my regular background appears and all seems to be normal. I ran my virus scan (Webroot), and that came up with no results. Not sure what to do next. Any advice on how to make the startup process go back to normal would be greatly appreciated. If there are is any more information I can/should include, please let me know! Thank you!

Hello, aliciatownshend.

Have you connected any additional or new hardware to the machine (USB hard drives, memory card readers, new keyboard, mouse, installed any extra RAM)?

Hi,

No, I have not. I have a printer that connects via USB but I haven't used that in several months.

What happens if you boot to safe mode - does everything appear as usual or does the white screen come up first?

Also, What is new or different since the last time everything worked properly (ie, new hw, new sw, virus, error, etc)?

I haven't added anything new or different recently, unless Windows had some automatic updates. I don't have any error messages or viruses that Webroot has caught. Once the white screen goes away, everything runs as well as it always has. I am not sure how to start in Safe Mode.

Reboot. As soon as the system boots start tapping the F8 Function key. This will take you to the advanced boot options screen. Choose safe mode.

Tried this, ran Webroot in safe mode, and it found nothing. I'm wondering if it's possibly another program trying to start right when Windows is?

You could chek startup programs via System Configuration utility. Look in Startup and Services tabs. Type msconfig.exe into searchbox. This is a very useful diagnostic tool for troubleshooting Windows startup. If you disable any services, it is prefferable to do so within Sevices(type services in the search box and select the second option.

If I've attached the image right, these are the programs which run at Startup.

I have seen this before. Or something like it, actually.
Next time you reach the Desktop, change the background through Personalize. Reboot. Change it back to your preference. Reboot.
Does that help at all?

I just tried this. When I selected a standard background provided by Dell, my reboot went back to normal. No white screen. When I chose one of my own pictures and rebooted, I had the white screen problem again.

That's not what I asked. I wanted to know if the problem was evident in safe mode. But it appears you've identified the cause now.

It could be a user policy in place.. give this a shot.

1. Launch “regedit” and browse to “HKEY_CURRENT_USER\Control Panel\Desktop.” Copy the following values with the suffix “Old” to the corresponding value without the suffix. Then delete the “Old” values.
- WallpaperOld -> Wallpaper
- WallpaperStyleOld -> WallpaperStyle
- TileWallpaper -> TileWallpaper

2. Still in “regedit” browse to “HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\ActiveDesktop” and delete the value “NoChangingWallPaper.”

MarkGS,

I tried to follow your instructions, and was able to, but found nothing about Wallpaper, with or without the term Old attached to it.

Allan, sorry, I misunderstood what you were asking the first time. I tried Safe Mode again and I cannot say for sure, as I'm not sure how long it should take to log on to Safe Mode. My icons did eventually appear, but no background except for black. It was almost a full minute before my desktop completely loaded. I'm assuming that not displaying a background is part of how Safe Mode works.
