I changed slots.. It starts low on memory and after some time it reaches 85% ...
A memory leak is possible. There were a couple Windows services, like superfetch, and at times, windows defender, that ate as much ram as was available, but never released any of it.
I hope this isn't a case of malware. Also, chrome is not good when it comes to memory management. It just sits there and eats and eats. If you're consuming a lot of flash-based content, I wouldn't be surprised if you ran out of RAM within a couple hours.
