How to remove a computer infection…manually

Congratulations!  You’re still with us.virus removal smiley

Let’s spend the next chunk of time getting into a bit of detail.  You need to know a few things….

1)  GO AND DOWNLOAD HIRENS BOOT CD.  Where?  From here in our Downloads section, it’s free and it’s great.

Got it? Great, here’s a video on how to burn it to a CD.

Why burn it to a CD and what is it?

Your windows Operating System runs from your hard drive.  You turn your computer on and it checks the boot sequence and boots into the first Operating System it finds.

Well here’s the thing…you computer will boot to the Hirens CD first if you tell it to.  Usually this will happen automatically but you may need to alter your BIOS or simply press F12 or F9 just after you turn computer on, this will bring up your boot menu (watch your monitor when you turn the computer on, it will tell you which key to press – look for ‘boot device’ or ‘boot menu’ or something similar).

Once the Hirens CD has settled down to it’s menu screen.  You will get the option to boot into Windows XP.  Do this.

So, step 1.  Burn the CD.  Here’s video, it’s not ours as we haven’t made one yet but it’s the same thing.

Done?  Let’s go.  Remember boot to Windows XP.

Ok this means that your computer needs to be SATA compatibility mode

In what you say?

Remember SATA from our computer fundamentals section?  SATA replaced the old IDE ribbon cables that connected to your hard drive but XP is optimized for the older style IDE cable so you need to tell your computer to run in compatibility mode.

1) Go to your BIOS.  For a more in depth explanation you should read our computer fundamentals guide but basically you need to tap the F2 key on your laptop or computer keyboard as soon as you have pressed your power button to turn it on.  Do this and go into Set Up.

2) Have a nose around in your BIOS.  Usually found in the advanced section you will find something related to SATA Mode.  Select ‘compatibility’, save and exit.  Reboot to Hirens.  Choose XP.

My laptop will not boot up

Ok so your laptop will not power up, let’s troubleshoot this issue.


You should read through our guide at This guide details the boot process for both a PC and a laptop.

Try and determine from this guide at which point your laptop fails.

The questions to ask are these:

Does my laptop POST?

If your laptop does not get through the Power On Self Test then you have a hardware problem.

Power On Self Test (POST) Troubleshooting

The POST screen will give you an indicator of the type of problem that it is facing.

Use our laptop disassemble guide and remove all components that you can i.e





You may have other external devices such as a usb keyboard and mouse plugged in or external drive.  Make sure you take these out too.


Try powering on again.  Any luck? If yes then try re-introducing the components one at a time again.  It’s perfectly possible that a bad connection was preventing one of these parts working properly and “re-seating” it has now made a good connection.

What if you still can not get past the post?

The chances are you have a motherboard issue.  Replace the motherboard or retrieve your data from the hard drive and buy a different laptop.

My laptop starts to load Windows but blue screens

Again, this could be down to faulty hardware.  You have a choice here, either:

1) Boot into Safe Mode and go to Hardware devices and disable each device, reboot and check.  If it boots then re-enable each device until it blue screens again.  You then have your culprit.

2) Carry out the steps as per the POST troubleshooting (i.e removing components) and try rebooting.  Again, re-introduce them one at a time until you find the culprit.

Why does my computer blue screen at startup?

There are a number of reasons but the most likely one is down to a driver issue.  Drivers are the software that allow Windows to talk to the devices on your computer.  Your Windows Operating System and also your drivers update from their respective manufacturers and it’s possible that these updates may conflict.  The result is that computer will produce the Blue Screen Of Death (BSOD).

Another reason could be faulty hardware and the way to determind this is as above, by removing components, rebooting and re-checking.
