Hi am Ashik. I think i can help you

Could you please give me a screenshot of that bar ? (Press Command(Apple) + Shift + 3. This should create a screenshot of your Mac into desktop. Then upload that screenshot into here)

I took the screenshot and then opened it. It's not showing the vertical bar. Very strange. Any other suggestions?
Expert:  Ashik replied 7 years ago. vertical bar in screenshot ?? weird..!

Okay...try this;
Make sure that the computer is shut down. Press the power button. Immediately after you hear the startup tone, press and hold the Shift key. Release the Shift key when you see the gray Apple and progress indicator. This will boot your Mac in safemode. (SafeMode looks like normal booting and its takes time to boot)

Then goto System Preferences>Accounts and click Login Items and uncheck or remove all unwanted intems.

Then goto ~/System/Library/StartupItems and delete all files inside the Startup items folder. (Don't Empty the trash)

Restart your Mac and let me know how it goes......
