Free Adobe Acrobat Writer (Alternative Software for Abode Acrobat)

If someone asks a question do you have Adobe Acrobat on your system, 95% of the people would say yes, and when you ask them to convert a word document to .pdf they would come back saying that I have Adobe Acrobat reader installed.  Adobe Acrobat Reader is freeware, which can be used to view .PDF files whereas Adobe Acrobat, which can be used to create and edit .PDF files, comes at a cost.


There are several freeware Acrobat Writers available on the internet. You can check www.download.com for several freeware Acrobat Writers.  I am reviewing one such freeware Acrobat Writer doPDF. Please feel free to let me know your views and comments and if you find a better tool please share it with me so that I can add it here.


doPDF doesn’t provide In-Application editing i.e. you cannot open a PDF document in doPDF GUI and Edit it. What doPDF does is it creates a Virtual Printer in your Control Panel > Printers. You can design your document in any application and convert the document into .pdf by printing the document using the doPDF virtual printer. You can download doPDF from the below link.

Please get back to me if you need any further clarification.

Think before you print…

I would dedicate this Blog for the environment. I am someone who never thought about the environment, for example I always used to throw the paper plates I eat and cool drink bottles I drink out of my car onto the road without even thinking, What am I doing? I never felt it wrong until I had a friend, who doesn’t like to do that. After her warning me few times I realized what I am doing. And now I don’t drop them out but drop them in a dust bin.


It’s a very small thing which we need to do and these small things would cumulate to make a difference. I would also say that we need to educate people around us that small things make a big difference. So my Blog today would be part Technical and part Nature Saving.


I would like to talk about Printers and printing. What is the cost of an Inkjet Printer? The answer would be a few thousand rupees depending on the functionality of the printer. What is the cost of the Ink Cartridge? The answer would be a few thousand rupees depending on the make and model of the Cartridge. I have seen printers in the market which sell for 3000 INR and the cost of the Ink Cartridge would be 2000 INR. So is the actual cost of the printer 1000 INR.


The answer would be No. The Printer manufacturers actually sell the printer at a loss and would make up by selling the Ink Cartridges. On an average an Inkjet Printer Cartridge would last for around 500 prints or 6 Months. So if you buy a printer and use it for 3 years you are actually paying him 3000+12000=15000 INR.


You might say that we can use off-market or refilled cartridges, then you need compromise on print quality and manufacturer warranty for your printer. So when are you thinking of buying a Printer choose Laser over Inkjet. Because laser printers use Toner in place of ink and would last few thousand copies compared with the few hundred copies inkjet cartridges last.


Also make it a habit to print on both sides of the paper. Agreed it would need some effort if you don’t have a printer that supports duplex printing, but you can always print odd pages first and then print the even pages.

A blog on Windows…

What is an Operating System? A good answer would be “A set of programs that provide a GUI to interact with various devices in a computer”. This definition would hold good until a few years back, when an operating system is just a few icons and menus that you see when you switch on your computer. Operating systems provided file and device management using a Basic GUI.


But with the development of computers, operating systems also evolved a lot. From simple file and device management solution, modern day operating systems should be stable and secure the data stored on a computer. The data stored on a computer can be anything from music, movies and photos to data that you have generated and stored in different files. It takes only a small virus, a power surge or a device failure to destroy data.

Today’s operating systems try to anticipate such scenarios and issue warning messages and take pro-active steps to minimize the data loss. I would talk about Windows XP and Windows Vista because 80% of computers run on Windows Operating system and Windows Vista is an upgrade to Windows XP.

Windows XP has been around for 8 years now and in considered one of the best operating systems released by Microsoft. When Windows XP was released it was considered a resource hogger. Windows XP required 128 MB of RAM to run smoothly. And there are many complaints from long installation times to frequent crashes. Microsoft released Service Pack 1 and things changed. Most of the security holes are fixed and Windows XP became stable. Windows XP was built to give a better user experience by easy installation and plug & play capability.

After a few years with XP, internet threats have grown and Microsoft started bundling Anti-spyware products along with Windows XP. This didn’t help much, and since Windows XP is the most used, hackers tried to find ways to break into Windows XP systems. This triggered the need for a more secure operating system and there came Windows Vista into picture.

Some of the problems with Windows XP are that password protection is not secure enough, users can use Bootable live CD’s like miniPE or Road Starter to bypass Passwords and access the file system. The other major issue is Internet Explorer 6 which is the number one target for hackers. By exploiting the security homes in IE6 hackers can take control of IE and hence the Windows XP box. And last but not least, when you try to search for a file under Windows XP, you have a terribly slow search tool.

Now its Windows Vista which is structurally more robust and is much more visually appealing. Vista comes with Encrypted File System (EFS) which takes care of file level security. Vista allows one to encode an entire partition or hard disk with just a few clicks. In Windows Vista Internet Explorer runs with restricted permission. If a malicious piece of code enters the system through the browser it cannot do much harm, since Vista simply refuses to permit to run it. File Searching has improved a lot with Vista.

But 2 of the night mares with Vista are getting your old hardware running and the annoying popup prompting you to allow or block any action you have performed.

How to troubleshoot your Mother Board?

Troubleshooting is the process of knowing the issue; determine the reason for that issue, finding a fix for the issue, applying the fix, then checking if the fix has fixed your issue. These are the steps you need to check before you fix any issue and putting everything back to normal. Before starting the process make sure that the issue has not resulted from a change in options in Windows Settings or BIOS or some Virus or Spyware activity.

Your mother board is the backbone or nervous system of your computer, every device in your computer depends on your mother board to ensure optimum functionality. It connects all the devices in a PC and checks that devices are communicating effectively between them. Common sign’s of mother board failure are that the PC won’t boot, doesn’t reach the BIOS test screen, scrambled text during and after the BIOS text screens, unusual system hangs, different combinations of devices not working.

Since all the devices are connected to the motherboard certain devices may not work if the mother board is having issues so be sure to test those devices before throwing then out and buying new devices.  First step would be a inspection of the mother board, to make sure all cables are connected properly, the fans are running at optimal speeds, and that the BIOS battery is working.

If the cables are not connected properly, the mother board may refuse to start. For example in some old mother boards you can connect the IDE Cable in the wrong direction. Ensure that PIN 1 on the mother board matches with the Color Coded Wire on the Hard Disk Cable.

Dying fans are another cause for mother board issues. An old fan would operate at lesser RPM and might not provide sufficient cooling for the CPU, and if the CPU temperature reaches a Particular level the Mother Board would halt the system. Also check for any broken or leaking capacitors and burn spots on the back of the mother board, these can immediately render a motherboard useless.  

Other major reason for Mother Board failure would be an ageing SMPS Units. You can test your power supply in 2 ways. There are software’s like Mother Board Monitor and ASUS PC Probe (works only with ASUS MB) which would give you details about the Voltages being used by the Mother Board or you need to get a spare SMPS and test it by swapping with your current SMPS.

If you can borrow a friends mother board you can try exchanging the motherboard with yours to see if it resolves your issues, if your PC works fine then you need a mother board replacement. If you think the motherboard is faulty and it is still in warranty you should be able to send it back to the manufacturer for a new one. Ensure that when you buy a mother board you should keep all of the packing and the box and warrenty cards, and there would be some labels that will bar the warranty if tampered with make sure you do NOT tamper them.

Which is the best anti virus program now?

Symantec, McAfee and Trend Micro are the Big 3 in the Antivirus Industry. They have several products which deliver.

In my 10 years of computer experience, in which i sold more than 200 computers, installed more than 1000 Computers and trouble shooted countless computers, i always feel that what ever the antivirus it should have the Latest Definitions to provide effective protection.

It’s hard to clean a file which is infected with virus, so you should make sure that the virus doesn’t enter your system in the first place. For this you need to install the antivirus with the current definition files before connecting to the internet or opening any CD which you bought from your friend.Norton is very slow, i have heard this from majority of my customers, but they should understand it depends on which version of Norton you are using. People generally use Norton Internet Security which is basically just not an Antivirus, but firewall, IDS, Antivirus and Anti spam in one application.

So when you compare running the above against AVG Antivirus which is a Virus only scanner your system would be definitely slow. But you should also take into account the protection if offers.

My first choice would be Symantec Antivirus Corporate Edition 10 if you want a Virus and Spyware solution and Norton Internet Security if you want all in one solution. But remember Symantec, McAfee and Trend Micro charge for subscription to get the updates.

I have used AVG in some cases and would give a 5 Star rating for its abilities.

If you want to pay for your Antivirus go with Symantec or McAfee. Free would be definitely AVG. If your system is infected with Virus and won’t allow the existing Antivirus to run a scan and won’t allow installation of New Antivirus you can use McAfee Stinger.



It’s a single EXE file which would run and clean the Viruses. You can copy the EXE file to a boot CD and run the Application booting of the CD and running. This would allow the EXE to run and clean viruses without loading the Windows file system and hence effective cleaning. 


Above link would allow you to download Stinger and has instructions on how to use it.

A blog about Display Settings…

This Blog is for everyone out there using a computer. I would try to make my post as much non-technical as possible, but if you need some clarification please get back to me with a comment or an email or an offline message… 

When you are buying a computer you try to buy a Good Graphic Card and the Good Monitor you can buy with the money available. In most cases the Mother Board has the Graphic Card integrated into it and you might have bought a CRT or TFT/LCD Monitor. 

After getting your computer, do you check weather the graphic card and monitor are configured optimally to give the best display resolution? The answer would be No in most of the cases. Let me explain you why. 

In 99% of the cases in assembled computers I don’t see the drivers of the Monitor Installed. It would be installed and configured as a Generic Color Monitor. So if your monitor supports better refresh rates or resolutions your System would not be knowing that and hence wont try to display those resolutions and refresh rates. 

If I ask you where you should configure your resolution, most of you would have an answer, but if I ask you where to change the refresh rate I am sure very few would have the answer. When you right click on the desktop and select Properties and go to the settings tab you would find a slider to set your resolution.  

If you click the advanced button and go to monitor tab you would see the drop down list to select the refresh rate. Higher the refresh rate less strain for your eye. So go ahead and select the highest value you see there.

Sometimes your display would go blank when you select a refresh rate which is not supported by your monitor don’t worry, just wait for a minute and your Graphic card would reset the refresh rate to the older value.

Now you can select the value which is lesser than the highest value until you find your monitors highest supported value. Installing the latest drives for your Graphic Card and Monitor would improve the quality of the Display a lot.

So keep checking the website of the manufacturers once in a month to find any updated drivers.  If you need any further clarification please get back to me.

Associating a file with an extension in Windows….

Every file has a file name and a 2, 3 or 4 letter extension. Generally it’s a 3 letter extension which tells Windows which program it needs to use to open that file. If you accidentally open a  file with a different program then Windows assigns that program for all the files ending with that extension and you need a registry cleaner to fix the issue.


You might wonder what a Registry cleaner has to do with file association. Once you read further you would understand. All files that are saved in a computer are saved with a file extension. The extension would be .doc, for Microsoft Word document or .xls extension for Microsoft Excel document. Operating systems like Windows would use these extensions to map programs with the file and automatically open the program when a file with a particular extension is opened. But the file association can go wrong in two scenarios. The two scenarios are. One when the program needed to open that extension fails to load and the other case would be when the extension or association is wrong. All such information is stored in the registry of the operating system and if the extension or association goes wrong or the program does not work the data or file is redundant and will fail to load. This will remain in the registry, as it is not automatically deleted. Here you need to run a registry cleaner to fix the issue.


You can download a Registry Cleaner from the Internet. You can go to www.download.com and search for “Registry Cleaner” and downloaded a freeware version of Registry Cleaners that come as the search result. Generally the Registry Cleaners are small programs which would take few minutes to download. Once downloaded you can run the Installer Package (Download File) and follow the instructions to install the software. Registry Cleaners run in two stages. Stage one would be to scan the registry for redundant entries such as bad associations or extensions and unused keys. This process may take few minutes depending on the size of your registry. The second stage is to clean the registry with the registry cleaner you have download.


There are a huge number of free registry cleaners that can be downloaded from the internet for free. TweakNow Registry Cleaner Standard 3.0.1, Free Registry Cleaner 4.4 and Abex Free Registry Cleaner 1.1 are some free registry cleaners which I would recommend from www.download.com. Any registry cleaner would remove redundant associations for files that are inoperable because the associated programs not working.


Registry Cleaner software remove duplicate and un-used keys present in the registry. So regularly running a registry cleaner on your system would keep the registry optimizaed resulting in better performance of your PC.
