My computer is running very slow. It happened suddenly from one day to another.
I checked for a virus or similar with Malwarebytes, Spybot Search & Destroy and AVG. Nothing was found (checked another time a week later, same result).
The Task Manager showed that only 1,5 of 4 GB RAM are used. The CPU is at nearly 0%. That seems not to be a problem.
But when I open the Ressource Manager it shows that my hard disk has 100% time with maximal activity without writing much (most of the time: nothing). While being inactive (I am doing nothing except viewing the Ressource Manager) there are some tasks which bother me (mainly svchost local service network restricted). Sometimes they go away and the computer is working properly, sometimes not. Another important point is that the answering time of the tasks who are doing smth with my hard disk are often over 5000 (the record was 16.000).
Even if my computer is working nearly properly (you can work but need to wait for each website 2 minutes and for a program to start nearly 5 minutes) you often see the "no response" (don't know how it is called in english, sorry for that!) at the upper window of the program.
I downloaded Speedfan (https://en.wikipedia.org/wiki/SpeedFan) and did an online analysis. Here are the results:
The funny thing about these results is that I did (more than one time) chkdsk (I think with the values: /f /r ). He found something and repaired it. Could it be that I forgot one time the value /r and the repaired some important thing but didn't recover it so my computer is going crazy?
I don't know what i can do anymore; tried my best and hopefully someone can help me furthermore. Do I need a new hard disk like the online analysis of speed fan suggests?
Thanks in advance!
