Several devices share the network, others use P2P to watch movies, etc., it will drag the router to death, restart the router will be some, the long-term solution is to change the router with speed limiting, and then set and allocate the network speed.

Microsoft's system retains 20% of the network bandwidth to the system, you can take this part and use it, open Start - Run, enter: , open Group Policy, select Local Computer Policy - Computer Configuration - Management Template - Network - QoS Datagram Scheduler, double-click Limit on the right side to reserve bandwidth, set to disabled.

Aging or improper use of hard drives is also one of the reasons. Professional software can be used to troubleshoot the problem, and if the damage is serious, the hard disk can only be repaired or replaced. 4。

There are compatibility issues with hardware and software. 5。The memory footprint is too large, ending unnecessary programs or the memory configuration is low.

5。There are logical or physical bad sectors in the hard drive.
