If you're not getting a blue screen error that looks like the below skip to the next Fatal exception section.

1. Identify the blue screen by locating a line containing all capital letters with underscores instead of spaces, such as the above example, BAD_POOL_HEADER. Write this information down. If you do not see anything written in all caps with underscores like this, skip this step.
2. Get either the STOP: error message at the top of the error, or in the "Technical Information:" portion of the error. For example, in the above error it's STOP: 0x00000019 ... write the first potion of this error message down.
3. Finally, if technical information is shown write down the file and the address.

Common Troubleshooting Strategies and Techniques


The following article is based on years of experience.Being a good computer technician is based on experience but also in reading and research. I Challenge veryone not only PC technician can fix computer problems but you also can fix this problem just keep reading and keep searching from the internet Directron.com is one of the site how to fix computer problems. It is provided as a free service customers and visitor . Ho you are welcome to distribute these computer support tips free to your friends and associates as long as it’s not for commercial purposes and you acknowledge the source. . All of us will start from basic here are the basic troubleshooting techniques and Strategies in troubleshooting minor computer problems.


Here are five common-sense techniques and strategies to solve common computer hardware problems.


(1) Trial-and-error


Personal computers are highly modular by design. The most powerful trouble-shooting technique is to isolate the problem to a specific component by trial-and-error. Swap compatible components and see if the system still works. Try different peripherals on different machines and see if the same problem occurs. Make one change at a time.


(2) "It’s the cable, s—–."


More than 70% of all computer problems are related to cabling and connections. Ensure all cables are connected firmly. IDE and floppy ribbon cables and power cables can often go loose. Ensure microprocessor, memory modules, and adapters such as video card and sound card are inserted correctly and didn’t "pop-up" during transportation.


(3) Don’t be frustrated!


Don’t be afraid of computer problems. It is often the best opportunity to learn. Trouble-shooting is part of the fun of owning a computer. Imagine the satisfaction you could get by solving a problem yourself.


Of course the fun could ran out quickly once you are frustrated and have spent too much time on the same problem. If you feel frustrated, it’s time to leave it for a while and go back with some new ideas or call someone who can help. Rule of thumb: You shouldn’t spend more than three hours on the same problem at one time.


(4) Take notes!


Take notes of what you have done and all the error messages. You may need to use them later. For instance, when you see an unusual blue screen with an error message, copy the entire message onto a piece of paper. In many situations, that message may point to the right direction in getting the problem solved quickly.


(5) Take a look?


It’s OK to open a computer case and take a look inside. There is only 5V and 12V DC voltage supplied to the components outside the power supply. Those who have never seen the inside

how to remove autorun.inf

Computer Virus attacks!


There’s a strain of computer virus that infects the file server and workstations of the computer laboratory of Hercor College, Roxas City, Capiz, Philippines. It hides itself by using the name ctfmon.exe (Ctfmon.exe monitors the active windows and provides text input service support for speech recognition, handwriting recognition, keyboard, translation, and other alternative user input technologies.) It was detected by TrendMicro 2007 as PE_VBAC.A virus and as MianCrypt.Gen virus by AVAST.


The said virus hides itself inside a folder named Recycled. The folder has a hidden/system/read-only attribute, that’s why you can’t see it if you will use the Search window. When your system is infected by the said virus, it infects every drive connected to your PC by dropping VCAB.DLL to the internet temporary folder and creating the CTFMON.EXE to folder Recyled & AUTORUN.INF to the root directory of every drive. That’s why when you connect your USB sticks to the infected PC it will be infected immediately, the USB disks will be the new carrier for the virus. The program runs every time you start your computer because it copy itself in the Startup folder of the Start Menu. It also run every time your insert the infected USB disk and it triggers every time you Double-Click the infected drive (bcoz of the AUTORUN.INF). The virus infects .EXEs and .DLLs.


To check if your system is infected by the said virus without using an antivirus, do the following steps:


Go to command prompt.
Type CD\ in drive C to go the root directory
Type DIR /AH and press ENTER key. This will display all hidden files in your drive C
If you see a file AUTORUN.INF and a folder Recycled, then your system is infected.
Try doing this to your USB drive and check if your USB stick contains the same folder and AUTORUN.INF, if it does then your system is really infected.
To remove it download and install a trial version of Trendmicro and scan your system.


To manually remove it (but i’m not recommending it especially if the infections of Bacalid is very high try using an anti-virus such as McAfee or TrendMicro’s PCCillin) follow the following steps (This is the step I take when i repair my computer without an internet connection. Note you should understand what you’re about to do, you try it at your own risk!)


Boot your system in Safemode
Go to command prompt, in Drive C do the following commands.
Type -> ATTRIB -H -R -S AUTORUN.INF then press enter
Type -> DEL AUTORUN.INF then press enter
Type -> ATTRIB -H -R -S Recycled then press enter
In Windows Explorer in Safemode, remove the folder Recycled in drive C use Shift-Delete to delete the folder.
Repeat Step 3 to 6 for all drives of your system including the USB drive.
Search for CTFMON.EXE in your system using the Search of Windows found in Start Menu. If you find a file that is not located in C:\WINDOWS\SYSTEM32, delete it immediately. Dont forget to empty the recycle bin afterwards (Usually the virus will copy itself in the Startup folder of the Startmenu. Check if the file is present there and delete it then.)
To disable autorun of drives (i.e. everytime you double-click a drive or cd or usb, it is auto open) follow the following step:


Click Start->Run->type REGEDIT.EXE
Go to this key from the register HKEY_CURRENT_USER\Software\ Microsoft\Windows\CurrentVersion\Policies\Explorer
Look for the entry NoDriveTypeAutoRun, double click the entry
Type a new value : 0FF (Hex) for the NoDriveTypeAutoRun, this will turn off the AutoRun for all drives, and press ENTER
Reboot the system.




Viruses that uses Autorun.INF


There are several viruses that uses the autorun.inf to spread itself such as the Bacalid (hides itself in ctfmon.exe) and the RavMon.EXE. These viruses set its file attributes to System+Hidden+Read-Only attributes so some anti-viruses will have a hard time detecting or finding them. These viruses save itself in the root directory of every available drives of the current infected computer and runs itself every time you Double-Click the drive. In USB Sticks and CDs that are infected by the virus runs automatically especially if drive autorun is enabled for the current drives (which is usually by default, autorun for drives are enabled).


Autorun.INF is usually used by CD Installers to autoplay their installations but Hard disks by default should not have AUTORUN.INF in the drive.


Now, it is possible that your computer is infected by those viruses if you try to display the content of the your computer through command prompt, using the dir /ah command. Y




Disable AUTORUN from Registry


Now you can disable the AUTORUN for all drives by configuring the registry. Open the registry by typing regedit.exe to the command prompt (if your still at the command prompt) or execute it in Run. Look for the HKEY_CURRENT_USER\Software\ Microsoft\Windows\CurrentVersion\Policies\Explorer as shown below:


Double-click the NoDriveAutorun DWORD entry and type the value HEX: FF (255 in Decimal). (If the NoDriveAutorun does not exists, you can creat it by right-clicking the right side area of the regedit window, then click New->DWord Value -> type NoDriveAutorun) Close the registry and restart the computer. This procedure will disable all the autorun for all drives of your computer and at least will prevent the autorun function of infected USB drives or CDs and avoid the infection of viruses like the Bacalid and RavMon.exe
