Today, when I powered up my computer, i have noticed that it has been on 'Welcome' for 10-15 seconds, which is more than usual 'up to 1'.
But I ignored it. However, while I was playing game, it froze for a moment several times.
Ignored it again. But, when I started Firefox, and waited and waited and waited... and waited, I have came to a conclusion that my computer runs slower than usual.
I've ran task manager and saw that my RAM memory is 3,98/4 GB full. Also my hard drive is 100% busy all the time. Indicator is constantly on...
Then I checked running processes to find out that they combined wouldn't spend more than 2 GB of memory.
I've already had this problem on my laptop before, but there was some kind of WMP updater or something taking this, but nothing here.
Anyway, I've restarted it and all, and scanned my system and did everything I could think of, but something's wrong.
What is taking my RAM? How to bring it back to normal?
P.S. I have Windows 7 and 8 developer preview installed, but I had it before the problem occured. Win8 is not having difficulties...
