MY EXPERIENCE ON HOW I RESTORED MY DESKTOP COMPUTER DELL MODEL: OPTIPLEX GX620 BRAND FROM THREAT OF DANGEROUS HACKERS

Hacker hacked my system for a long time to the extent that they are consuming my Broadband airtime that are meant to last for a month under few days or weeks depending on the capacity and this made me to be subscribing a maximum of 4.5 Airtel ISP gigabyte monthly to meet up with their demands, yet these unscrupulous and wicked personalities that are even living close to my area relentlessly did not give up in attacking my system. So as an ICT personnel I have to apply my skills to figure out solutions to these problem which even at this moment I have not finally concluded their mission of doing such act but what I know is at the moment at least I can stop so many from gaining entrance to my system except some stubborn ones that has manipulated my BROADBAND MODEM through my IMEI number and other information that came with the modem which they got through entering my Wi-Fi that does not have control point yet.

Now these are the radical steps I took which did not prove successful initially, but now is yielding result, though I have tried so many ways to completely eliminate their operation through my Wi-Fi to my Dell Desktop Optiplex GX 620 which I said earlier did not have a control point or a button to turn it off or on and as a result these nearby scammers cease the Wi-fi to have access to my system including my files. I have to set up Bitlock Key encryption password to lock up my document, I wanted to lock up the entire Hard Disk but already they have tampered with the (Trusted Platform Module)TPM through BIOS and other roots as well as disabled it completely, so the security Bitlock Key was not possible to the Hard Disk because the TPM security was not enable. So I have to go through Program Bitlock Key in Application software like Microsoft word to secure some important document from scammers; these I achieve by taking the following steps under ms-word 2007:
(i)                Clicking on the office button before the menu “Home” on the menu bar to display the drop down list
(ii)              Select “Prepare” on the dropdown list to view options
(iii)            From the options, then select Bitlock and lock up your document with Username and password
I think with this your main documents are secured a bit.

Now, the second step I took was to diagnose my system for intruders or hackers through MS-DOS or command prompt by issuing command at the MS-DOS environment like:
C :\> NETSTAT A-         to display Options

Then I will select: “-A” from the options to display and know if potential hackers have intruded into my system and I type the command as follows:
C :\> NETSTAT –A

The above command will display the active connections and the intending active connection which has not succeeded in gaining entrance to your system. The active connection will display “Established” under the STATE of the active PC while others waiting or trying to gain entrance but has not succeeded yet will show listening. So I tried the process  to disengage these established intruders .

Now, this is how I go about trying to disengage them, this achieved by pressing down at once the keyboard CTRL +SHIFT+ESCAPE keys at once to pop up the task manager where all the programs running in your computer both internal and external will be visible. Now trying to locate their Process Identification (PID) to right click it and end their process which will finally terminate their operation on your system, it happened that the Hackers has also manipulated the PID also in disguise. So merging the PID in established Hackers from MS-DOS with the one on the Task Manager do not rhyme. So there are other alternatives to locate. But I skipped the alternative initially to try some other thing to see if I can eliminate them completely through those means.

So I have no option than to go and purchase NORTON ANTI VIRUS SOFTWARE and run it in my system. I could not successfully installed it initially due to their continual use of magnetic device to hook my system through Wi-Fi to manipulate what I was doing, but finally installed it, but they later used that means and disable the anti-virus twice so that they can be gaining entrance. Though the antivirus sanitize my system when it was successfully installed, but it did not solve the problem of the four identified established connection. I have to try Norton power Eraser as I was connected to the internet. It did not still solve the problem of the threats on my system which I discovered through “NETSTAT –A” command at the MS-DOS Prompt. These became a battle for a long time, as these hackers penetrate my computer system and change my Broadband settings as they want.

Also I came to discover that antivirus software is there to detect new threat, terminate them and constantly protect your system while reimages windows repairs professional software is there to heal damages these viruses have already caused. So I decided to download and also run reimages windows repairs professional software from the internet as well to see if I can fix this problem myself. Reimage could not fix the problem as well.

Now, I have to go back to the task manager and select system column from view menu. Now click on the “commit size” to see the size of the memory of all active system connection. I have to end their process as you merge it with the image name column which they have manipulated as well, they can still manipulate even the sizes, but you need to use your psychic to detect their movement and action, sometimes you may click the wrong program and end it thinking they are part of the hackers but sometime computer will warn you when you want to do that. Now one thing here is that as you are ending them you need to be observant with the MS-DOS COMMAND which is NETSTAT -A and NETSTAT –S, to make sure that your assignment is completed. If they still exist, continue to end the suspected process until you wipe them off. And while working with your computer keep on checking them through this means because sometime some will disguise and hide, when you are off, the will surface to operate again on your system and this is how I restored my system to control hacker from exhausting my Airtime.

MY EXPERIENCE ON HOW I RESTORED MY DESKTOP COMPUTER DELL MODEL: OPTIPLEX GX620 BRAND

It was on the 24th of August 2016 that I boot my Desktop Computer Optiplex GX 620 Brand of Dell Model. After loading the Operating System when cool booting, on arriving where I will insert the administrative password, it will restart itself. So it could not successfully boot to Desktop windows and these remains continues process showing that the startup operating system software was corrupt. So I have to insert window7 DVD to correct the problem. But the computer could not see the DVD disc on the DVD WR which I later replaced the drive with another one.

Now after setting the Bios to boot Windows 7 from DVD Disc, I was trying to switch from booting normal to booting from DVD when I press F12 and selected DVD as option, immediately I hit the ENTER KEY from the input device which is the KEYBOARD, the whole thing on the screen went blank except a white underscore blinking cursor, the power on the Key board and mouse went off as well. I did everything possible to see that the USB Keyboard and the Mouse received light or being dictated by my system, but it could not work out. I took it to repairer who could not solve the problem as well.

After two days, I came back to the same computer with the help of a repairer we brought out the RAM from its sitting and clean it and replaced it back to its sitting. Then we use electric blower and remove some dusty part of the system units to include mother board. To my greatest surprise I powered the system; everything came back to life including the mouse and the keyboard. I have to continue with the repair myself from this point because the repairer is not well experience in software programming. Now I insert another Windows 7 DVD disc to run installation and correct the startup problem. But the Repair operation System in windows 7 DVD inserted was not compatible with the existing Operating System in my DELL SYSTEM. So I have to go to nearby Computer Accessory dealer and purchased WINDOWS 7 DVD DSIC which has 32 and 64 bit systems and I inserted it now right inside my room to run the installation repair.

When I began with the repair, it was not an easy one like normal installation process. I have applied professionalism to correct that startup corrupt operating system which ordinary startup repair could not correct. Now the process of correcting this problem advanced as followed:

I have to Undergone Dual Boot:
During the first booting, after inserting the WINDOWS 7 DVD and switching successfully from Booting normal to Booting from DVD Drive by pressing F12 and using the arrow key to arrive to the main menu as well as selecting it with Enter Key. I arrived in an environment where there are options to set Language, I have to set the language options and click next on the menu as well. Remember I am booting from the DVD WINDOWS 7 Disc. The next action I precede after the next option appeared was to click on SYSTEM REPAIR from three opting presented in that environments. Now the SYSTEM REPAIR option now searched for valid operating System and reports that “Windows found problem with your computer start up option? Do you want to apply repair and restart your computer? Then I clicked repair and restart and reboot again to window 7 repair environment.

Now this time I have to click next at the Keyboard selection prompt and when the SYSTEM RECOVERY OPTION screen appeared. I have to select from the options “Use recovery tools that can help fix problem starting windows. So, I first selected system Restore, after completing the process and restarted, on the second boot to the same options I have to select “COMMAND PROMPT”.

Now trying to fix this startup error with specific MS DOS command became relevant and the main problem solution to this error repair installation. So, on the COMMAND PROMPT environment which is MS-DOS I have to type the following command to fix the error:
X:\Source>CD..                                 (THIS MEANS CHANGE DIRECTORY)
X:\>                                                     (PREVIOUS COMMAND WILL BRING YOU HERE)

Then type the next command:
X:\>bootrec.exe /Fixmbr
The operation completed successfully

The computer will display the above message as confirmation after issuing the second command and the message is “The operation completed successfully”

The third Command goes like this:
X:\>bootrec.exe /Fixboot
The operation completed successfully

The computer will still display the above message as confirmation after issuing the third command and the message is “The operation completed successfully”

The final command issued was:
X:\>bootrec.exe /RebuildBCD
Scanning all disks for windows installations please wait since this may take a while…

The above message “Scanning all disks for windows installations please wait since this may take a while…” is displayed by your system after issuing the last command. Then after sometimes the computer will still respond with the under listed statement:

Successful scanned windows installations.
Total Identified windows installation: 0
The operation completed successfully
X:\>

Then I have to close the command prompt environment and click the first option from the options displayed from the INSERTED CD which is startup Repair option

The first repair process may take sometimes like 2 hours depending on the capacity of your Hard disk, mine took 2 hours 30 minutes to complete the first round. So I have to wait until the process was completed; at which  I saw the messages telling me that:
(1)             Startup repair cannot repair the window automatically. And we need to note that these messages are as are result of the radical changes made by removing other drive. I ignored the send or not send option that appeared as I proceed to close the message from “X” BUTTON in the upper right corner of the Send/Don’t Send window.
(2)             Then view advanced options for system recovery and support option and from the main menu once again click “STARTUP REPAIR” the second time. This time the process may take few seconds to complete and when prompted :

“START UP REPAIR COULD NOT DETECT A PROBLEM”

Click finish and run the final “startup repair” again from the option. After this last one click finish and remove the system repair DVD and Restart. Your system will boot to windows completely without error.
