    Casual Laptop performance issus

    Hi

    For some time I have issues causing sudden slow down, shivering sound, caper picture etc
    This can happen when playing music from HD or online, when playing a movie or playing a game like windows hearts in which the cards simply goes slow.

    I have noticed that in many cases, if not in all cases, at the same time it seems that the CPU usage jumps dramatically, sometimes up to 70%-80%.

    Sometimes when it happens, I can see a program that consumes at least 20 - 30% CPU, but each time it is different program.

    Also in most cases if I open Window's task manager, to check the running process and their CPU & RAM usage, I don't really see that the CPU is really working hard,
    as sometimes the most heavy process takes maybe 20% CPU (chrome, uTorrent, VS, etc) and all the other do not really sums up to 80%.


    I scanned the machine for viruses and other stuff - nothing found.
    Cleaned tmp files, registry, internet files etc. nothing changed.

    Eventually I restore an old image made few mounts ago when the laptop worked beautifully. Didn't help.
    Due to this fact I came to conclusion that this is a hardware issue.

    I considered tools to test the machine hardware performance.
    I tried PC Wizard - but I do not really know to "understand" the results, or even what test is relevant.

    Need some suggestion to better diagnose the problem.

    The Lenovo T410 laptop has a dual core Intel I5 cpu and 8G ram, and installed with Win 7 x64 bit

    Have you ever cleaned the dust and junk out of the air passages?
    Probably overheating and the cpu is slowing down to protect itself.

    Canned air blown through the air passages DOES help.

    Hi Train,

    Does this mean I should open the laptop case?
    Also, is that is the case, I would assume to see some indications for CPU high temperature. Isn't it?
    I am using PC Wizard - and I can see thereat least three temperature clauses (CPU, Core #1, Core #2)

    What should be the normal values here?

    TX

    No need right now to open the case. I take my laptop outside and with the tube attached to the canned air , I blow out the passages and try not to breath the dust and junk that comes out.

    Post the temps , you can copy/paste from PC Wizard into your next post.

    I will try to catch the temp when is happens, see if the temp is higher
    For now - this is what I have. Couldn't find where to copy this information - so I PrtScr it, and load the file

    Another question is why using Canned air?
    will hair dryer be suitable for that?

    56C is fine, I get curious at 60C and get real curious at 65C.

    We need the extension and the air is dry too.
