If your PC has crashed and you can no longer access your data, you still have options to recover it. First, try booting your system in Safe Mode or using a bootable USB drive to access the data. If that doesn't work, you can remove the hard drive and connect it to another working computer as an external drive. Using data recovery software like the BLR Crash PC Data Recovery Tool, you can scan the drive and recover lost files. In severe cases, where the drive is physically damaged, you may need to consult a professional data recovery service. Always remember to back up your data regularly to prevent loss in the future.
