Do Some PC Repair and Earn Money

Tweet

I've been busy these past 5 days repairing few desktops and a netbook. So I got a lot of work to do and of course earn few bucks. Some of the problems I've encountered regarding those desktops pertains to incompatible memory, overheating processor, video card, bad hard disk drive, and does formatting too. Beside, I'm making some sidelines too like LAN installation. In fact, yesterday I got one from our neighborhood.

Well, it's really hard managing my own business because I can't afford yet to hire someone to do the job. Right now, I'm just the one who is making a lot of effort in managing my own business. However, my family is there assisting me anyway.

Regarding those desktop, two of them was already turned over to the owner. The one had a problem with its memory, it doesn't fit into the slot so I replaced it with the right one which is a 128 DDR and format the drive since its been corrupted already. 

The other got a problem with its processor. Its overheating so I applied thermal paste around the processor replacing the old and dried one. Aside from overheating, the built-in graphics is seems not good enough so I suggested the owner to buy another motherboard for him to save more than maintaining the defective one. So I sold him my ASUS motherboard and closed the deal. It's been 3 days from now that I haven't got any feedback from the owner, so I assume that there was no problem so far.

Even at this time, I'm still doing some troubleshooting (regenerating HDD) while making this post. I still got 2 more PC to repair. I hope to finish them this day.

I'm enjoying my job and my life. I still have so many things to learn from my day to day activities in life and just want to share those ideas I learned in computer maintenance..

Brontok Worms Removal

My client's personal computer was brought to me for check-up and repair. He said that whenever he attempts to open it, it automatically restarts. I have encountered this situation before and so I suspected that it is infected by a virus but not the same virus I encountered before. I've tried first to disk clean up the HDD to recover some space. I found out that the HDD has little amount of free spaces which is much less than the required amount of disk space. Take note that in order for a HDD to work properly  we must maintain at least 15% of free HDD space. Otherwise, we can expect a slow performance and sometimes hang up. During defragmentation also, we also need 15% of free space to allow the procedure. I got tired of doing trial and error, so I decided to apply combofix to remove the viruses and those files infected.

After I applied combofix, for over 10 minutes, I was able to recover 35% of free spaces compared from the previous which is only 9%. or a total of 45% after combofix. Combofix did find the virus identified as Brontok. The Brontok worms have almost eaten up the free spaces that is why the computer suddenly restarts due also to bad registy. Combofix restored the registry and those hidden files which was unaccessible prior to applying combofix. Then I started again to disk clean up and defragmenting the HDD.

The Brontok worm is a virus originated from Indonesia which is an attachments to an e-mail named Kangen.exe. Kangen means I miss you so much. The Brontok is also known with other names.

The PC is back to normal. It works smoothly.

Tips:

  1. Study and learn about viruses and its behavior.

  2. Never open an email if it is from an unknown source.

  3. Maintain the required amount of HDD space which is 15% of the total HDD capacity.

  4. Apply Disk clean up and Defragmentation once or as needed.

  5. Never forget combofix, it's effective!
