Brand new 16gb ram alienware laptop.. memory usage 100% .. ?!


I bought a new laptop its brand new.. i just finished installing most of my things..

At random time, i hear my laptop fans and when i check the process manager my physical memory reach close to 100% usage... however when I check the process manager, nothing there would account for all that usage...

I got 16gb ram, if i calculated the software open on the task manager it would only account for like 4gb of ram maximum.

I have same software open when it show 5gb ram usage, and when it decide to peak to 16gb...

Right now its showing only 5gb ram and I got everything open. ( Everything i use : World of Warcraft, Firefox, skype, etc)

I cant provide screenshot of it when it spike to 100% usage because It didnt do it since few mins now, as soon as it do it i will add screenshot of my process.

But my process dont show nothing over 700mb usage so there no reason for it to go to 100% usage.
