What's wrong with your toolbar? Which Toolbar? Your problem might be you have too many toolbars. Toolbars slow your browser down and clog up your screen.

If you are using Internet Explorer you get to the toolbars by clicking View on the menu bar, then click Toolbars. You can check and uncheck the ones you want to appear or not appear on your browser. If you menubar is not at the top of your Internet Explorer browser, look over to the right and see if you see Tools or the Tools icon and click it, then click toolbars.

If you are running Windows 7 press and hold the ALT key for the toolbar to appear at the top of the screen. If you want it to stay there Click View/Toolbars then select Menu bar.

I have the 2436V (no speakers), but I suspect the solution will be similar. My screen was a bit to the left of the monitor's physical display area, and I was able to solve it using the built in menu (If you take too long deciding what menu button to press next, the menu will time out. Just start over if that happens. You will get faster with practice).

1) Press the menu button on the monitor (the menu appears).
2) Press the up button on the monitor 4 times to highlight the icon that looks like a slightly angled screen with yellow cross-hairs in one corner (the toolbar for positioning the screen appears - all 5 icons on the positioning toolbar are blue).
3) Press the menu button on the monitor to "enter" the selected toolbar (one of the toolbar icons turns green to indicate the selected tool on the toolbar).
4) Select the tool you need using the up/down arrow buttons on the monitor (I needed the one that moves the screen horizontally, you need the one that moves the screen vertically).
5) Press the menu button on the monitor to activate the selected tool (the meter above the toolbar icon turns green to indicate the tool is active).
6) Use the up/down buttons on the monitor to position the screen.
7) Press the menu button to exit back out (or, just let the menu time out).

Note: the disk that came with the monitor doesn't seem to have drivers for Windows 7, but allowing Windows to search online while updating the driver found a compatible driver online.

You can try this. On the log-on screen where you see your Account Icons try pressing ctrl alt delete. Some windows XP are configured that if ctrl+alt+delete are pressed on the lon-on screen the classic log-on screen window will appear, where you can type your username and password thus eliminating the use of the mouse.

Get your Mac OS disk out and restart your computer with the disk in the drive ANd while holding down the C key. This will start the computer on the OS disk system.
Once you get to the desktop, look for the top menu and launch Disk Utility. Run a repair and see if you get any indications that it found anything out of the ordinary.
Then restart as normal.
If it still doesn't work, I would recommend reinstalling the system software.

1. Adding Icons to the Task Bar


1. Click on the Start Menu to open it
2. Click on "Programs" and find the program for which you want to create an icon
3. Move your mouse pointer to the program you want to use
4. Depress and hold down the right mouse button while you drag the icon to the Quick Launch toolbar section of the Task Bar
5. When you release the right mouse button, a short menu will appear
6. Choose "Create Shortcut(s) Here." An icon will be created in the Quick Launch toolbar on the Taskbar


2. Deleting Icons from the Task Bar


1. Move the mouse pointer to the icon you want to delete
2. Right-click on the icon
3. Choose "Delete" from the short menu that appears. The icon has been deleted, but the program is still available to you on your hard disk


NOTE: If you have carefully followed the steps above to add the icon to your Quick Launch toolbar, deleting it will NOT delete the program from your computer, it will simply remove the icon from your toolbar. The program will still be available to you.

Also you can "Drag" the program, to the bar, and "Drop" it on it. Check out a freeware application called StartupCPL at http://www.mlin.net/StartupCPL.shtml. This places a Startup icon in your Control Panel which, when opened, lists all applications on your PC with a check box for each one. Simply put a check mark in each application you want to open minimized on startup. By the way, it states it is for Windows ME and 2000, but I have had it on XP for quite a while and it works fine.

It sounds like there is something causing the process explorer.exe to not start properly. Most likely a virus, but could be something wrong with windows itself. First of all, when you get to that white screen and there is no toolbar down the bottom, bring up the task manager (press control alt delete) and click the new task button down the bottom. Then type in explorer.exe and hopefully that will start up the toolbar down the bottom of the screen. you can also use the new task button to browse for any anti-virus program you have to run a scan to see what is causing the problem.
