10. Scan your hard disk drives or partitions for errors. This can be done opening My Computer, right clicking your hard disk drive selecting Properties, then selecting Tools tab (see Figure 10). Click on Check now box and the window shown on Figure 11 will pop up. Check Automatically fix file system errors and then hit Start. If you are scanning your boot drive (almost always your C: drive), the system will tell you that it cannot run Scandisk right now and that it will schedule it to be run next time you load Windows. Click on Yes and reboot (i.e. restart) your computer in order to make Windows to run Scandisk. Repeat this step for all hard disk drives and/or partitions your PC may have. This process can take a lot of time to be completed.
