We are sorry to hear that you are having issues with the boot up of your Lenovo IdeaPad 330-17 laptop. This may be due to a software compatibility issue. Be sure all of the software you have installed on the device is compatible with Windows 10. There is no need to install Microsoft Office software.  The software is already part of the operating system, you just need to activate the software with a purchased product key.  If you have installed a copy of Microsoft Office, this is conflicting with the existing copy on the system and this will slow your system down.  If you have installed a 3rd party anti-virus program, be sure that Windows Defender is turned off and that the trial version of McAfee Anti-Virus software is uninstalled.  There can only be one anti-virus program on the system.  You may need to restore your system to original factory default settings if any of the programing errors have occurred.  Because you are unable to boot up your device, you will need to use OneKey Recovery. This system is equipped with OneKey Recovery System.  There is a very small pin hole on the left side of the device, right near the Micro-SD card slot on the device. You will need a pin to push this reset button. Plug the device in. Let the battery charge for about 15 minutes. Push the reset button. The system should boot to a choice screen where you can choose "Restore To Factory Default". Select this. It will delete everything from the hard drive except the original factory install of the operating system. You will need to reinstall all programs and files after the reset. If you don't have copies of the files, try to make one before you restore by selecting "Boot to desktop" and trying to back up your files. If the problem persists, we recommend you call Lenovo Tech Support at: 877-453-6686.

This model is not user upgradable. All work on this device must be performed by a certified technician, so as to not void the warranty. Your certified technician can replace the existing solid state hard drive for a larger one. Regarding music product and DJ work, this will depend on the software you will need to use, its compatibility and requirements. We recommend you check with the specific software publisher web sites for the programs you will be using, for their compatibility with the Windows 10 Home 64-bit operating system and the minimum/recommended hardware requirements to run their program, then compare these requirements/compatibility with this system's configuration.
