It occurs that when I use Internet (Google Chrome or Mozilla) on Ubuntu and I have activity normally as to check Facebook or see a YouTube video, my cumputer uses too memory RAM until 100% principaly, or sometimes it use 100% of CPU, although before it didn't occur as now it happen. Its characterics are 4 GB of RAM, its proccesor is a Intel® Celeron(R) CPU 1017U @ 1.60GHz × 2. I didn't install software of PPA, since too much time, so it wouldn't can be the problem, or for that reason I think that it doesn't.
The reason of why, with Google Chrome or Mozilla, it begins this problem a time until today, I wouldn't be able to explain it, and I don't know solve it, except to reformat it, but I have various academics programs, as Xilinx ISE with PATH, and others which are expensive to install, and I would like to know better the problem, and solve it of practical way or, would there be a way that the problem was another? If I am on page without constant exchange of dates as this page, my computer don't arrive until 100% of RAM or CPU, but it can use more memory than I used to check.
