100% Ram Usage with nothing running?

[KingPho]

So I added fresh new windows 10 downloaded all my drivers and all the things my pc needs, after 1-2hrs my pc will be at 99% ram usage just from watching videos and surfing the internet and installing a few games on steam. After 1-2hrs after installing my drivers and stuff i been lagging a lot like my pc is real slow i cant load anything so i closed all my apps and installs and its still sitting at 99% and lagging hard takes me longer than usual to open task manager maybe like 5secs, Before i could open most apps less than a second.

Sounds to me like Memory Leaks

However, if you are using Chrome, the answer may be far simpler.

CHROME IS A RAM HOG FOR NO REASON.

 

Serious, it takes up 6 or 7 GB of  my RAM when i have it running, so i use FIrefox instead
