Extra Tip: How to Export Your Data When PC Keeps Freezing

If the seven instant ways are useless for your computer, you can search for a professional computer service. Before sending it to a repair shop, you can migrate your files, applications, and settings to another computer for reuse. Try EaseUS Todo PCTrans and apply the "Data Rescue" feature.

Step 1. Take out the disk from the old PC.

• Disconnect the power supply. Please take out the battery if it is a laptop.
• Open the case to see the hard disk in the old PC.
• Disassemble the shell by using a screwdriver to find the hard disk.
• Disconnect the hard disk and cable, then take out the hard disk.

Step 2. Connect the hard disk to the new PC.

Multiple connection methods:

• USB hard disk drive Enclosure:  Use this special device to connect the old disk and the Enclosure, and then connect to the new PC by USB.
• USB hard disk drive Adapter: It is a device like a "Cable". One end is connected to the hard disk, and the other end is connected to the USB port on the new PC.
• Desktop Computer: If the new PC is a desktop PC, the old disk can be connected as the second disk.

Step 3. Recover/Migrate the applications, files, accounts from the old disk.

1. On the new PC, open EaseUS Todo PCTrans and select "This is New PC" in the Data Transfer tab.

2. Choose "Transfer via disk" and click on "Next" > "Scan."

(If the old PC system disk's registry is corrupted, it will fail to detect your disk. There is no way to rescue your applications anymore. You are suggested to copy your file data as soon as possible to avoid further loss.)

3. Select the target disk you want to recover data from and click "Continue."

4. Your programs, files, and accounts will be listed after the analysis. Select the data you want to transfer and then click "Recover."

5. Wait patiently till it's done. When the transfer is finished, a reboot is required to refresh all transferred information.
