Cpu 100%?

  1. My computer will work fine, and then randomly it will be at 100% CPU usage when doing ANYTHING. Watching Youtube Videos, playing games, even when I am not doing anything on it, I will check on it, and it will be 100% once again. I am not sure how to show you the specs of my computer, I don't have the program link, I can do that if someone will provide me a link. My computer is well qualified for any of the tasks that I am trying to do. I have payed 3 Repair Shops to fix, and they have no idea what is wrong with it, I cleaned it out Yesterday, and no dice. If someone may help I would be very thankful.

    When this happens again check Task Manager and see what process is consuming the CPU cycles.

    I did, nothing at all. It does it even when theres no processes other then system ones

    As JMMD has suggested run Task Manager, you can do that by pressing Ctrl+Alt+Del and selecting Task Manager, then go to Process tab, and carefully examine all running processes and resources they are taking.

    With regard to system specs, please download CPUZ, install it and run it, then go to About tab, and save the out put file as text and attach it with your next post.

    Sorry, am actually software noobie... But i had K-Lite Full Codec Pack and then installed Total Video Converter, and then the very same thing started happening to me... I just took off the K-Lite and retained the Total Video Converter, and then i proceeded to reinstall the K-Lite again. This actually worked.

    So what i am suggesting is that it appears that the problem would be instigated by software, and not at all hardware. I believe the rest who posted are also along the same diagnostic lines. I suggest just follow thru on Archean's instructions. But in the event that perhaps you would rather not do it yourself (as i noticed you brought it to three shops first), then i would instead suggest bring it to a software specialist- it appears those shops are hardware specialists, hence the "no-fix" results...

    Alright here is my specs, I also forgot to mention that I thought it may be software or a virus, so I Wiped my computer fully and changes O.S back to windows 7 (This has been happening for over 1 year, and its at the point where I cant take it anymore) Anyways, here is a file. I don't know how to attach it, so I will only provide a link.

    Was the system running anything else when you created this CPUZ file?

    I am asking because if it wasn't, then the near idle temperatures of 50C/53C range for CPU are too high. Same goes for your graphic card at 65C.

    Ensure that the casing have good airflow (i.e. intake and outflow), and there is no dust etc. on any of the components including CPU/Graphic Card fans.

    Lastly, have you tried to check with Task Manager that what may be causing these slowdowns ... perhaps by eating up too much CPU cycles.

    Do you know what is the make/model of PSU (i.e. Power Supply Unit)?

    Voltage level on 12V rail is well outside the usual +/- 5% range, and also the temperatures inside the casing is hovering around 50C which again is bit on the higher side.

    Well I am not too amazing with computers, but nothing else was running when I was doing this test, I had the outer cover off (one side had no side), I just cleaned out the dust, so it may be a little better. I will run again if you want me to.

    One more thing with Task Manager. Select the Process Tab and verify that Show Processes for All Users (or something similar) is selected so you can see all processes. Sort the list by CPU use and you'll see what's taking over the CPU.

    System Idle Process is at 99%?

    That's normal when nothing is going on and the system is idle. If you launch a game, for example, you'll see the game's executable in there at some high percentage of CPU use.
