There are several possible causes of high physical memory usage, while the most common are two: one is to install a bad program, memory is occupied too much, the second is the computer itself is not enough memory.
And there are usually 3 ways to fix it:
1. Download some free memory software on the Internet
2. Set larger virtual memory
3. Buy another piece of memory
If memory usage is high, and you are using the WIN7 system, you can open Windows Task Manager click → resource Monitor → memory to see what is the most memory-using software. Please refer to the chart below ...
Install a bad program, now a lot of software does not do optimization so that the memory can not be automatically released after consumption, so the memory has been used to cause waste, and finally all the memory is used up, if you installed the WINDOWS7 system, let alone, 2GB memory is certainly not enough. It is recommended that you upgrade your memory to 4GB or higher after upgrading to a 64-bit system.
It is recommended to first antivirus, and then use some garbage software cleanup program to help you clean up the system garbage, and finally do some boot-boot optimization on it. There is a direct relationship between the number of processes and the physical memory consumed.
If you do not want to upgrade the memory, you can try to turn off some unnecessary boot processes to reduce memory usage. You can easily debug with tools such as 360: Killing Trojans, cleaning plug-ins, cleaning garbage, power-on acceleration, divided into one key optimization, startup items, services, these items can be optimized after the automatic operation of the process of the purpose, for some do not need to randomly start the program, you can choose to turn off its automatic startup settings.
