1, the blue screen problem you mentioned is the problem of hard disk drive file iastor.sys, and the hardware problem is relatively small.

2. This problem suggests that you can try to save important files and then reinstall the operating system using the original Microsoft system installation CD to solve the problem.

Note: If you need to restore the pre-installed system of the machine, you can directly contact the local gold medal service center for restoration. For the contact information of the Gold Medal Service Center, you can choose your province and city and the product type you use through the following websites:

This model of yours belongs to home notebook computer. Individual users can contact HP Gold Service Center to restore the system for free within one year after purchase. It is recommended that you bring the invoice and warranty card. If it is more than one year, you may have to pay the repair fee. Need to contact the maintenance center for consultation and confirmation.
