Computer very slow from time to time

HP Recommended
ProBook 470G
Microsoft Windows 10 (64-bit)

Hello Community,


all applications of my LapTop suddenly go very slow from time to time. This can happen twice a day or only once during a longer period. Once this is occuring,  only a new start will help until next time... Any idea how this can be solved?


Thanks in advance and best regards.

Generally, when a laptop becomes really slow to the point of being unusable, that is an indication of drive failure.  But since drives don't repair themselves, this problem starts out intermittently and gets more regular, and worse, over time.  It does not suddenly vanish and performance goes back to normal.  So, based on your comments, I would rule out drive failure.


Alternatively, Windows Update pushes out patches to PCs every week and when that happens, it takes over the PC, slowing it to a crawl, driving up the processor to 100%, driving up the disk utilization to 100%, and generally making the laptop useless and unresponsive.  But this only happens once a week at most, and if this is happening several times a day, then this is likely NOT the issue.


I would suggest you run diagnostics to see if it can find anything.  To do that, reboot the PC, pressing the Esc key repeatedly.  When the HP Startup Menu appear, press the key to run diagnostics -- usually F2 -- and see what it finds.
