How to fix a Hacked computer ( Part 2 )

This is the second part on how u can fix your hacked computer. In order to do that, you will need to reload your system by following these steps: 

Step 1

Insert your Windows DVD in your computer's DVD drive or plug in a USB drive containing the Windows installation files.

Step 2

Reboot your computer and enter the BIOS by pressing a specific key.

Step 3

Change your machine's boot priority so that it attempts to boot from the DVD or USB drive first.

Step 4

Save your changes and exit the BIOS. Your computer then reboots and loads the installation files from the removable media.

Tip

Refer to your computer or motherboard's documentation on how to enter the BIOS, and edit the boot priority on your machine.
Step 5

Select Install, type in your license key if the wizard prompts you to enter it and accept the terms of service.

Step 6

On the next screen, click on Custom and select the first partition.

Step 7

Click on Format to erase that partition's contents. Repeat this process for every partition on your hard drive.

Step 8

Once you have formatted all partitions on your hard drive, click on the partition where you want to install Windows and select Next.

Step 9

Follow the on-screen instructions to finish installing Windows.

Warning

Formatting your partitions permanently deletes your files. Consider saving the files you want to keep on a USB drive or external hard drive before formatting your hard drive. However, do not save files that may potentially contain executable code -- such as EXE, RAR or even DOC or XLS files -- as they might have been infected.
Dealing With a Network Intrusion

Hackers who successfully penetrate a network or computer usually do so by exploiting open ports on a router or machine. To prevent hackers from remotely accessing your entire network, consider purchasing a router and enabling its built-in firewall. Alternatively, to secure a single computer, enable the Windows Firewall.

Tip

If hackers were able to remotely access your computer despite your enabling Windows Firewall, it may be due to a misconfigured rule that allows insecure connections to pass through the firewall. You can reset your Windows Firewall rules by selecting Windows Firewall from the Control Panel and clicking on Restore Defaults.

Important Computer Repair Safety Tips

How To Stay Safe While Working On Your Computer In addition to being an afternoon of great fun (seriously!), computer repair can save you loads of time and money. No amount of fun, money or time is enough, though, to compromise your safety. Keep these important tips in mind as you work inside your computer: Remember to Flip the Switch Always, always, always remember to turn the power off before servicing anything. This should always be your first step. Do not even open the computer case unless the power is turned off. Many computers have a number of lights inside that serve certain functions so check to see that no lights are on. If any are still on then the power is probably not completely off. Many power supply units have a switch on the back, killing power to the device and ultimately the rest of your PC. If your PC has one, be sure to turn it to the off position. If you're working on a laptop, notebook, or tablet, be sure to remove the battery, as well as dis...

Medical experts remind us that "prevention is the best medicine" so as your personal computer support expert, I'm going to strongly advise that you apply the same logic to your computer!

Keep Important Files Backed Up The most important thing you can do as a computer owner is to consistently and reliably back up the data stored on your hard drive. Hardware used to be the most valuable part of a computer but those bits and bytes are no...

Explanation of a Computer Case

Image
The computer case serves mainly as a way to physically mount and contain all of the actual components inside of a computer, like the motherboard, hard drive, optical drive, floppy disk drive, etc. They typically come bundled with a power supply. The housing of a laptop, netbook, or tablet is also considered a case but since they aren't purchased separately or very replaceable, the computer case tends to refer to the one that's part of a traditional desktop PC. Some popular computer case manufacturers include Xoxide, NZXT, and Antec. Note: The computer case is also known as a tower, box, system unit, base unit, enclosure, housing, chassis, and cabinet. Important Computer Case Facts Motherboards, computer cases, and power supplies all come in different sizes called form factors. All three must be compatible to work properly together. Many computer cases, especially ones made of metal, contain very sharp edges. Be very careful when working with an open case to avoid ser...
