lenovo t440p, win7 pro (it was home premium, i have no idea why it is pro after resetting to default settings), i5-4600, 8gb ram
common question but i'm stuck a bit. firstly laptop was as fast as speedy gonzales, but for now it became extremely slow.
- no, auto launch is okay (little amount of programs)
- no, disk defrag is on my schedule
- no, there is no viruses (afaik) yes, i'm using ccleaner
almost the only thing that changed - hdd is used only by 60% and now i've got 4 users, but they are working separately.
what should i do and what i'm doing wrong?
thanks for watching
