EaseUS Todo Backup Home is a software which you can use to backup your data and & your entire system.
In case of any issues, you could just use the software to restore a system snapshot to get your PC back and running in no time.
Here is a list of the key features of Todo Backup Home:
Win PE Bootable Disk
One click system backup and recovery
Clone hard drive/partition
Pre-OS recovery environment
Outlook backup and restore
Windows 7 Libraries backup/restore
System snapshot
Incremental backup
Differential backup
Schedule backup
Event-based backup
Backup files/partition in Windows Explorer
Some of these features are not available in the free version, so I would recommend that you get the Home edition while it is being given away for free.
Normally the software costs $29, but you can get it for free from GiveawayOfTheDay. This promo is valid for 24 hours only and they do not offer free technical support or program updates
