Finder flashing after update

Question

so i've been have problems updating my MacBook Pro it seem that it doesn't want to update to 10.9.2, so with that I'm mind i tried to manually install the updates and still nothing my mac still says 10.9.1 after manually installing 10.9.2-10.9.5
...then i manually reinstalled the 10.9.1 (thinking maybe some files are missing) to fix any issues preventing my mac to update (maybe i might have deleted something when 'clueing my mac') or something this is my 3rd attempt to update my mac because of the same issue but yeah.
so anyways i installed it and then i restarted the computer manually (because it didn't ask me to) and usually when i start my mac the files i have on my desktop appear including the HD driver and nothing but my wallpaper
i noticed that my dock is very laggy when i navigate around it.
i went to 'force to quit' to see if i can resolve the issue by 'force quite' finder and its flashing ever second as I'm typing.
I'm unable to open and finder windows other apps i have on my dock open
my quicktime and my mail.app have that deleted icon on them "O\"
can someone please help me with this issue?
maybe some how uninstalling or reinstalling something to fix this issue?
sorry for the paragraph but i had to be detailed for those who are reading understand the situation

Answer 1

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
For this step, the title of the Console window should be All Messages. If it isn't, select
          SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar at the top of the screen.
In the top right corner of the Console window, there's a search box labeled Filter. Initially the words "String Matching" are shown in that box. Enter the name of the crashed application or process (Finder.) For example, if iTunes crashed, you would enter "iTunes" (without the quotes.)
Each message in the log begins with the date and time when it was entered. Select the messages from the time of the last crash, if any. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
☞ The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
☞ Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ User Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of crash reports. The name of each report starts with the name of the process, and ends with ".crash". Select the most recent report related to the process in question. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
If you don't see any reports listed, but you know there was a crash, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report—they're very long and rarely helpful.
