couple a times a week something suddenly is eating up all my availible memory.
some weeks ago i could se at the resource monitor that is was the svchost.exe, that has these services in use as seen in screenshoot, but now the resource monitor don't show svchost as a big mem hugger anymore. any help? my computer barely moves when this happens, only remedy is a reboot.
it is usually at 99% use.

opera always use alot of resources, but that only 5-15% so it is not that, the picture is to illustrate what programs that is running and svchost don't show up anymore as a mem hugger, and i don't know if it still that service that still use alot of mem or anything else

svchost.exe is also a system file that is used by the Windwse to run properly ...

always restart after a few hours of use. that refreshes the memory usage back to normal,keep a check on how high it goes to see if there's something unusual
