Some security tips

Published by:

Security is such a major issue these days, with all the spyware and malware lurking on the Internet; not to mention the nastiest viruses, worms, trojans, rootkits,  etc.

There are so many threats for our digital security. What can one do to protect themselves?

Well, there are a some things we can do as users:

  • First and foremost, develop safe browsing practices. Which means,  be mindful what websites you visit, what links you click on, what files you are downloading, and so on.
  • Next, no matter what kind of computer you have, turn on Automatic Updates for your OS ( operating system),Windows, Mac, Linux,  iOS and Android, regardless of brand or device. Android devices can get free antivirus on their smartphones and tablets from the Android Store, now called Google Play Store. Popular ones are AVG and Lookout Mobile Security.
  • Make sure you have antivirus software installed on your device and keep it up to date. Some free resources: AVG FREE , SuperAntySpyware, etc more can be found at .
  • Do not open attachments in emails that have been forwarded by more than 1 or 2 people, and even then, be wary; make sure the message comes from someone you know.
  • Do not share your password with anyone, unless you know for a fact who they are.
  • Speaking of passwords, try to make them as complicated as you can, so that the bad guys have a very hard time guessing them.

These are a few of the things that come to mind when talking about security on our devices.

Use common sense, stay updated, and don’t click YES on something you don’t know what it means. Google it first or ask someone who knows.


Phishing emails

Hi everyone,

A quick update on a new phishing email.

It is an email that comes seemingly from the IRS, the address looks something similar to no-replyczuf @ irs . gov (without the spaces) and it says that your tax return is not complete  or something to that effect.


Please do not download the file attached  but forward the email as it is  to


Be aware of all the online criminal activities, and use common sense when browsing the internet.


Very important: Keep your security software up to date, and back-up all your data.


More information about how to report phishing emails to the IRS  can be found  at : phishing .


Thank you.


Laptop has no video

Published by:

Hello again,

Recently I had a service call about a laptop that had no video at all.

The obvious reason and most common one is the inverter board (backlight can be a culprit too). If that goes bad, then the laptop screen will appear black. Another possible reason is the video cable; it can get damaged or become unplugged. The worst one is when the video card goes bad.

So in order to determine which of these is the culprit, you can do several things:

  • make sure the laptop receives power. When plugged in, look for the LED lights indicating the power on the laptop, is these are on, then your laptop receives power.
  • next, shine a flashlight on the laptop screen; if you can see a faint image on the screen, then it is the backlight or the inverter board. They can be tested with a tester to determine which is the bad one.
  • if there is no image on the screen when using the flashlight, the try to plug in an external monitor, to see if you can get video; if no video on the external monitor, then the problem is with the video card;
  • the way to determine if the problem lies with the video cable, is to open the laptop case and take off the screen, and manually check if the video cable is damaged or unplugged.

The good news is that all of these issues can be fixed with a part replacement.

First things first: have an antistatic wrist strap, every time you work inside a computer case.

Step by step instructions:

  1. Check your laptop specs to see if you have an integrated video card or a discrete one; if you have an integrated card, then the whole motherboard will have to be replaced, otherwise, only the video card needs replacing.
  2. We determined that the video card is bad and it is integrated on the motherboard; we need to find the correct part and purchase it.
  3. with the new motherboard at your side, start opening the laptop case;
  4. unplug the laptop ac adapter and take out the battery; set them aside
  5. take out the HDD, DVD/CD  units by flipping the laptop upside down, and removing the screws from the bottom of the laptop.
  6. once these are out, start removing all the screws from the bottom of the case. Keep them in a safe spot, and preferably separate from the rest of the screws coming out later;
  7. flip the case again, and remove the top plate holding the power button;
  8. remove the screws holding the screen hinges, and set the screen to the side, watch out for wires and cables; If the problem is the inverter board or backlight:
  1. remove the screws holding the cover on the screen, and take the monitor from it’s case, be aware of the cables and wires.
  2. Replace the backlight or inverter board, plug the cables back in;
  3. put the monitor back together and connected it to the main part of the laptop;
  4. after all screws are back in and everything is connected properly, check to see if the screen will light up. That is it for the inverter board replacement.
  • take out the keyboard, being careful not to damage the connector for the keyboard; there are two tabs on the sides, that need to be pulled up, the connector will slide out then easily.
  • remove the top part of the case;
  • unscrew the motherboard from the bottom case, if necessary, remove the screws holding the serial and parallel ports (depends on your model), for easy motherboard access.
  • remove the motherboard and set it down preferably on an anti static mat;
  • start porting the memory, wireless, fan, cpu, etc  to the new motherboard.
  • once everything is on the new motherboard, replace it back in the bottom part of the case and screw it down if necessary.
  • replace the top part of the case, and put the keyboard back in ( don’t forget all the wires and cables that need to be plugged in the motherboard);
  • attach the screen back on, and start replacing all the screws in the case
  • replace the HDD, CD/DVD, etc, back in the case;
  • at this point, you can plug the laptop ac adapter and turn it on to see if you get video.

If all the screws are back in and all the wires attached, then the laptop should power on, and video should be working just fine.

That’s it, hopefully you didn’t go crazy working with all the tiny screws and pieces.

My advice, if the cost difference between replacing the part or getting a new/used laptop is not too great,  don’t even bother,  just get a new one.

Good luck and ask your questions; I’ll do my best to answer.


A few Computer Tips

Published by:

Hi again,

I thought I’d share a few tips for a better computing experience:

  1. Make sure your PC case is located in an area with good air flow.  Enclosed spaces can restrict air flow, thus inhibiting the cooling process.
  2. Two or three times a year, open the PC case and by using a can of compressed air, blow the dust out of the case. Overheating is one of the most common reason why PC components fail. Overheating PC’s also run slower, so make sure your computer case is clean of dust and other debris.
  3. Keep your OS (operating system) up to date by either enabling Windows Automatic Updates from the control panel, or by downloading the updates manually and installing them. Microsoft releases new updates every week, and every Tuesday ( also known as update Tuesday) new updates are available for Windows OS’s.
  4. Keep your security software up to date; most anti-virus programs run silently in the background, downloading updates every day, mostly for their virus database. Some standalone anti-spyware and anti-malware applications need to be updated manually.
  5. Keep your files organized, by either using the system built in the OS, like My Documents, My Pictures, etc.,  or by creating your own filling system. That way you will know where everything is when you need it.
  6. Back-up, back-up, back-up; there are a number of ways to do that, and the simplest is to copy your files on an external storage device.
  7. Export your contacts, messages and favorites/bookmarks to .csv /.html files, and save them online or on an external storage device. That way, in case of system failure, you have your latest data when you need it.
  8. Periodically do some housekeeping tasks, like running the clean-up tool built in the OS.
  9. Even if you don’t think that your PC needs to be turned off when you’re done using it for the day, it is always a good idea to at least restart the computer. By turning the PC off, it will also consume less power, and allow the hardware components some much needed rest.
  10. Always practice safe surfing, which means that when you go online, visiting web pages, DO NOT CLICK/DOWNLOAD randomly; make sure you know what it is you are clicking on; a Google search always yields results that have information about a certain website, link, etc.(or ask a professional PC technician).

Well, these wold some tips to get you on your way to a better and safer experience when using PC’s.

Any questions will be answered appropriately.
