First, the problem you mentioned is probably that there is something wrong with the machine's boot file, which causes the machine not to boot into the operating system normally. I suggest that you can save important files and reinstall the operating system in the following ways to see if you can solve the problems you encounter:
① Insert the installation CD into the CD-ROM drive, and then restart the computer.
② When the "HP/COMPAQ" sign appears on the screen, click the "F9" key continuously.
③ Select "Built-in CD/DVD ROM Drive" and press Enter to confirm. ?
④ For the installation process of Win 7, please refer to the official Microsoft document:? ?
Second, if your machine can't boot and install the operating system normally, it may be related to the system or hardware-you can enter the bios to test the hard disk: keep clicking F 10 to enter the BIOS- storage -DPS self-check, and select your hard disk to enter the waiting test. It is recommended to connect an external power supply and keep the power supply during the inspection. ?
1. If the hard disk passes the test (generally good, passed or successful), you can back up the data and reinstall the system; ?
2. If you can't access the bios, or the hard disk detection fails (usually it will prompt fail or error), you can contact the Gold Service Center for on-site hardware maintenance. ? You can check the nearest HP Gold Service Center through the following website: www.hp.com.cn/asc? Consult an HP partner: Select: Maintenance Service? Please select the product and product type to be repaired, then select the province, fill in the city, and click Query.
