I have answered a lot of such questions, so I won't say much and give you a solution directly.
The reason is simple: it has something to do with your operating system and driver!
If startup items, background services, Trojan back doors, and viruses all affect the speed of your machine!
Especially when you slowly open a web page, the CPU usage rate is very high! It's most likely a Trojan horse!
You can use safe mode to kill viruses, optimize the system, clean up garbage and registry!
However, most of them have many tails, and you can't clean them up!
I suggest you follow my long-term accumulated experience and handling methods:
First of all, the operating system must install the non-ghost version, and the pure version!
If you are using the original win7, I suggest one-click restore and skip this!
Second, the system driver is installed correctly.
When installing drivers, you must first install the motherboard chipset driver and restart it as required, and then install other drivers. Recommended installation order: motherboard chipset driver-> Graphics driver->; Sound card driver->; Modem driver (if any)-> Card reader driver-> LAN (network card) driver->; Wireless network card driver->; Shortcut/function key driver-> Power management software->; Camera driver->; Touch panel driver of touch panel->; Bluetooth Bluetooth driver, restart after installing motherboard driver and graphics card driver.
Third: windows system online upgrade, full patch!
Fourth, install necessary anti-virus programs and other applications.
Only one antivirus and fire prevention software can be installed. There will be conflicts if there are too many. The number of simultaneous startup and service programs will increase, which will increase the occupation of system resources. At the same time, there will be false positives!
Fifth: system optimization and disk defragmentation
Use system optimization software, such as windows Optimizer, to handle startup items, services, registry and junk files.
Sixth: one-click GHOST, backup system, easy one-click restore!
Seventh: Install your necessary programs!
In fact, there are many game software that can be installed without installation. Just make a green version yourself. Not here!
Eighth: Reuse the system optimization software once to deal with startup items, processes, services, registry and junk files.
Ninth: If you use 360 tools, please uninstall them all. We just use it as a system tool! Don't need him to pretend every time!
If you do this, your system will be safe!
@ I suggest that if you fill up 4G memory, the performance of the notebook will be significantly improved! @
Good luck!
