Why Computer Hangs?

1 Overheating of processor / Motherboard. If the cooling fan is faulty, the processor gets heated up and ceases to work beyond a particular temperature.

2 Faulty hard disk drive.Hard disc problems also hangs the computers in case the important Operating System files needed to keep the computer running, become in-accessible.

3 May it be virus

4 OS or software Problem

Solutions : To Fix the PC hangs (computer hang problem),you need to follow two steps:

Step1: Check that the cooling fans on the processor is working properly or not. So ensure that the fan is working fine and is clean. If not, then get the fan replaced. Also check for the additional fans on your computer casing/cabinet(if any).

Step2: To Fix this, run a disk scan which checks for disc errors and fixes the bad sectors (some examples are scandisk and check disk utilities in windows). If there are bad sectors which can not be repaired, then you need to replace your hard disc.

step 3: Check ur Antivirus Update and scanning

Step 4: If, still ur problem continuously Format and reinstall ur OS and software

Tip for enhanced performance: Once there are no bad sectors and the disc scan is complete, do a de-fragmentation of your hard disc partition(this may take long time), it will help the computer to access files easily and computer runs better(also fast in some cases).
These three steps will fix your computer hangs considerably.

Computer Restarting Trouble

Autorun.inf Removals Tools

This is the standard procedure to delete the Autorun.inf file

Normally when a virus infects a windows system which causes a drive opening problem, it automatically creates a file named autorun.inf in the root directory of each drive.

This autorun.inf file is a read only ,hidden and a system file and the folder option is also disabled by the virus. This is deliberately done by the virus in order to protect itself. autorun.inf initiates all the activities that the virus performs when you try to open any drive.

You have to just delete this file and restart your system to correct this problem.

Follow the set of commands below to show and delete the autorun.inf

1. Go to Start then Run and type cmd and press enter. This will open a command prompt window. On this command prompt window type the following steps.

2. type cd\ press enter

3. type attrib -r -h -s autorun.inf press enter
please note the spacing: no space between the dash and the letter & a space after the r h and s

4. type del autorun.inf press enter
if the PC returns a "file not found" message - check the spelling for autorun.inf

5. if you have a d drive: type d: and press enter for d: drive partition. Now repeat steps 3 and 4. Similarly repeat step 5 for all your hard disk partition.

Restart your system and your trouble will be fixed. Except the program that caused the problem is still in your computer.

Make sure you are connected to the Internet. and download Malwarebytes' Anti-Malware program.
Double-click on Download_mbam-setup.exe to install the application.
When the installation begins, follow the prompts and do not make any changes to default settings.
When installation has finished, make sure you leave both of these checked:
Update Malwarebytes' Anti-Malware
Launch Malwarebytes' Anti-Malware
Then click Finish. MBAM will automatically start and you will be asked to update the program
before performing a scan. If an update is found, the program will automatically update itself.
Press the OK button to close that box and continue.

On the Scanner tab:
Make sure the "Perform Quick Scan" option is selected. Then click on the Scan button.
The next screen will ask you to select the drives to scan. Leave all the drives selected
and click on the Start Scan button. The scan will begin and "Scan in progress" will show at the
top. It may take some time to complete so please be patient. When the scan is finished, a message
box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
Click OK to close the message box and continue with the removal process. Back at the main Scanner
screen, click on the Show Results button to see a list of any malware that was found. Make sure
that everything is checked, and click Remove Selected. When removal is completed, a log report
will open in Notepad and you may be prompted to restart your computer. (see Note below) The log
is automatically saved and can be viewed by clicking the Logs tab in MBAM.
Note:
If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts.
Click OK to either and let MBAM proceed with the disinfection process.
If asked to restart the computer, please do so immediately.
Failure to reboot will prevent MBAM from removing all the malware.

Thank you to XPCMAN for this solution

1 Step

1.) Open Notepad and do not write anything in it. Just go to File > Save as (save it with the name: autorun.inf)

2.) Copy the autorun.inf file that you have created in the above step and paste in your “Pen Drives”

3.) Remove your drive.

After removing the pendrive, re-insert in your PC. Now your anti-virus will not detect any virus in your PC. And Your pendrive is 100% safe to use.

2 step

There is a much simple way to remove the Autorun.inf file. Genreally when you refresh the windows explorer view a bounded virus process recreates this file. This file is attached to many events of windows explorer including OPEN, REFRESH, etc. Simple stept to remove the virus activation:
You must close opened explorer windows.

1. open up a command prompt (i.e. cmd.exe) >> to load it go to Run, type cmd, enter.
2. Now to remove virus's attributes (in order to delete it type following line by line and execute them pressing enter.
e.g.
F:\
F:\attrib -s -r -h *.* If there are any malicious EXE files those are now visible so if unnecessary delete them too.
F:\del autorun.inf

3. After finishing above, quickly remove the pen as soon as posible (just after executing del command).
4. Now your pen is without virus activation config. file. Now you can safely delete unnecessary EXE files on it.

3 step

to get rid of Autorun.inf related viruses do the following in all of your removable and local drives.
if autorun.inf already exists then,
open cmd (command prompt) and change the directory to the root of (infected) drive,
i.e C:\ has autorun.inf
C:\>del /a:rhs c:\autorun.inf | md c:\autorun.inf
this will remove autorun.inf file and will create autorun.inf directory which will prohibit viruses from creating autorun.inf files in same drive.
repeat the process for all drives.
you can also create files named Recycle, Recycler, Restore, System etc in all drive to prohibit creation of folders having these names (thoese folders are created by viruses to complete their process in every drive)
and you can also create directories of same name that of virus file i.e fbak.exe, fix.exe, sscvihhost.exe, system.exe, etc

To disable autorun.inf and autoplay just download and run disable.reg and add keys to the registry.

REGEDIT4
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\IniFileMapping\Autorun.inf]
@="@SYS:DoesNotExist"
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]
"NoDriveTypeAutoRun"=dword:000000FF

MS DOS

Short for Microsoft Disk operating system, MS-DOS is a non-graphical command line operating system created for IBM compatible computers that was first introduced by Microsoft in August 1981 and was last updated in 1994 when MS-DOS 6.22 was released. Today, MS-DOS is no longer used, however, the command shell more commonly known as the Windows command line is still used and recommended. In the picture to the right, is an example of what a MS-DOS window more appropriately referred to as the Windows command line looks like under Microsoft Windows

Today, most computer users are only familiar with navigating Microsoft Windows using the mouse. Unlike Windows, MS-DOS does not use a mouse and is navigated by using MS-DOS commands. For example, if you wanted to see all the files in a folder in Windows you would open the Windows Explorer, in the command line you would use the dir commant.
