Start, Desktop, Task Manager wont work

This is basic troubleshooting.

First without any information, when is the last time you cleaned the inside of the computer, and do all the fans work? I once had a computer start doing this, it was from over heating. Let's start there. It could be one of thousands of things that have gone wrong.

Next, is there a reason why it was not updated? I am not a fan of frequeny system updates, but sometimes it's unavoidable.

Heri Hermansyah wants answers to this question
hyjacker 4 years old post , ok.
that is a very old desktop motherboard, number
no OS stated by you or the OP 4 years ago
so no possible answers. lacking such a super key factor.
there are 3 sources of drivers, (and no virus)
1: ms.com (at the Microsoft PnP servers, click device manager yet, and right click audio device , update driver, yet?
2: samsung get it there. ( I see it is too old now, not there)
https://www.samsung.com/us/support/downloads/

3: or find out what chip is there (ask me) and we get the driver directly from the chip maker, learn the OLD PCs do not have drivers for windows 7 or 8 or 10.

so next time post your OS first.

In your task manager go to new task button in the applications tab. When you press new task button it will give you a run dialog in their type explorer. This should reopen your task bar and enable you to use the start button again. If this does not work it is time to backup and reinstall windows.

if you mean that just shows a bue screen and no task bar or desktop ..this is probably from a virus attack that cause it ..Try to press ctrl+alt+del this should show the task manager and in the task manager run a new tas ...and lunch the windows explorer again ..
or just run from task manager the system restore..and try to restore it to an earlier date that worked..To do that pres those like I said ..and than in the task manager on screen choose file and new task (run) and type system restore..and hit enter ..ths should run it ...choose the date that you know it worked and run it ..If it do not restore you have to reinstall or ..to use it for the moment find the desktop address and add it in the start-up for that run MSconfig and press enter ..in the start menu ..choose normal ..and enter ..and choose restart ..it should get along well again..

You should be more specific as to when the problem occured as the solution for each instance would be different. However since there is no other information, please proceed with the following generic solution.
if there is a disk error you should either press ESC (to remove the alert window on the screen) or hit CTRL + ALT +DEL.
within windows you will get the option to start Task Manager. Choose Task Manager. Locate Windows Explorer in the list of processes, select it and press End Process.
All your windows along with desktop and system tray will disappear.
Then within task manager Goto File > New Task.
A Run command window will open. type in explorer.exe and press enter. Your windows along with desktop apps will restart and this time there wont be an i/o error.

Disable the task manager...
Because they will close the cafe mate in the process thats why it will disconnect to the server...
