Now im on a computer I'll post some detail regarding reinstalling Windows (even if you don't use it it is useful info to have)
Firstly make sure you have some recovery media with which to reinstall to the factory state if you have not done so already.
If your laptop came with Recovery and Driver&Utility discs then this is it. If not (which I expect given how new it is) then your HDD will contain a hidden recovery partition which will be visible in the Disk Managment utility. You can check by pressing WinKey + R, entering "diskmgmt.msc" in the run box, and hitting enter. Do NOT touch this partition. To access the recovery options on system startup for purposes such as recover to factory state, press F9 during boot.
Now I will outline a general approach for doing a reinstallation of Windows.
1. Backup all your files that you wish to keep on an external HDD.
2. Delete backed up files from computer.
3. Image entire HDD using Macrium Reflect (see below), saving image to external HDD. (This backup is just a
temporary backup in case anything fails, so dont use it to save files you want to keep)
4. Do a factory reinstall from the recovery partition (pressing F9 on boot to access recovery options).
5. Image the entire disk including recovery partition using Macrium Reflect. (You can keep this backup forever as a means of a factory reset in case your recovery partition is no longer accessible for whatever reason). Once this is done successfully you can delete your image created in step 3.
If you dont mind the bloatware you can stop here. However if you want to do a clean install of Windows 7 continue reading. Note that it is still good to have your Macrium image of the factory install as it will have all the necessary drivers.
Clean Install
1. When d
ownloading the ISO you need the correct version for which your computer is licensed (Ultimate, Professional SP1-U, Professional N SP1-U or Home Premium). Unfortunately the link provided doesnt give checksums, but the md5 checksums for the English Home Editions which i downloaded (and seem to work) are:
X17-24209.iso (64bit): 971843A457B6E0DB0AF61258CBE7256A
X17-58996.iso (32bit): 0AFA9359C62DC7B320205D3863C60385
These will let you ensure that the iso downloaded properly.
2. To burn the image to a DVD use
Astroburn Lite or your own favorite burning program. Note you cannot just copy the ISO onto the DVD as a file, you need to burn the image using a image burning program such as Astroburn Lite.
3. Record the details of your network adapters and video cards. These things typically do not work properly on a clean install due to Windows' poor driver support. To do this first open device manager (winkey + R > mmc devmgmt.msc > enter). Expand 'Display adapters'. Double click on the listed device and note details including device name (manufacturer + model). Expand 'network adapters' and note the same details for both devices (one is LAN, other is Wireless), also note Location (this will help identify the device in case it shows up as 'unknown' upon fresh install.
4. Download the appropriate drivers from the vendors websites.
5. Also run a
driver backup as since you are installing the same OS version they will compatible. Of course this is not 100% garunteed to work hence downloading wireless/graphics drivers which may be more difficult. Save the folder containing all the drivers on you external HDD.
6. Shutdown the computer and boot your clean Windows 7 DVD which you burnt in step 2. If DVD does not boot automatically press F12 during system startup to select DVD drive.
7. Follow prompts to install Windows.
8. Install the display and network card drivers. If you couldnt download them restore them from the driver backup you created. If either of the network drivers fail to install properly, try the following:
Go to device manager and find the network adapters. If not listed, they will be listed as an unknown device. Compare the location (which you recorded before wiping system) of each unknown device to identify which ones are the network adapters. Once you have identified the device go to the driver details of the device and choose to update driver. Manually search for your backed up driver, in the subfolder containing the backed up drivers for that device (the drivers for each device will be saved in individual folders).
Using Macrium Reflect Free Edition
I have used it to image my entire HDD, including recovery partitions and it works. Download and install, following prompts. Start the program and make sure you create the boot CD when prompted (you will need a blank CD-R for this). You can create the disk later if you cant create it now. Then (from under the 'Disk Image' tab) select the 'Create a Backup' tab. From here you check ALL partitions of MBR Disk 1 and click 'Image this disk...'. Follow the prompts and save the image to an external HDD.
To restore an image to the HDD, insert the boot CD which you created from Macrium Reflect, and press F12 on startup to show boot prompt. Select the CD/DVD drive to boot. This will load Macrium Reflect outside of your Windows OS. From here you can select the image from your external HDD and restore it to you internal HDD. After restoration, remove the CD and reboot. Your computer will be exactly the same from when you created your image.
Here is an alternative method to backing up your factory restore hidden partition. Although it says you need a flash drive greater than 16GB, im not sure that a 16GB flash drive will work. Maybe an external HDD might work if formatted FAT32? Anway,

For free antivirus
Microsoft Security Essentials is very light and one of the best. Note that some people might dis it due to certain (older) detection rates which were slightly poorer than others, but it is currently very much up to par in comparison to others like AVG Free and Avast!
[edit]
Ever used a Linux based OS like the very popular and easy to use Ubuntu? It has good driver support (better than clean Windows) and can run many Windows applications via WINE. If you're interested you can have a look. You can install boot a live CD to just try it without installing it too. Something for everyone to consider
edit2:
just thought I'd mention that a Macrium image of your system after a factory install is better than the in built recovery partition due to the speed. A factory install takes ages as it wipes partition, cops files and then goes through this configuration process which takes ages. My laptop takes 2-3hrs. However restoring a Macrium image of the fresh install takes less than 30 min. Hence my recommendation to create image of clean install in step 5.
