Laptop high memory usage problem?

[Dominic]

27% average memory usage is not high. In fact it's really good. You have nothing to worry about at the moment.

Edit: Web browsers are more complicated than you suppose. ^_^

Computers today have various power saving measures that dial back performance when not a lot is going on. In portable computers it helps save battery life when not connected to an outlet, for example. Starting a new program will naturally spike the CPU. It seems worse if the PC is running at one of these lower power states but I assure you that it's normal behavior.

Google Chrome spawns multiple processes. It separates various things, such as plugins like Flash, into their own processes instead of running them in the "main" process. That way if Flash were to suddenly crash it won't take out your entire browser session. This is not uncommon for a web browser. Firefox does something similar.

Finally svchost.exe stands for Service Host. Windows services went from using exe files to dll files. Thing is, dlls can't be loaded directly so they need a host which is where svchost.exe comes it. It's often used to group related Windows services together so you might have several of these running at any give time which is nothing to be concerned about.

There doesn't seem to be anything abnormal about your PC at this time.
