How to fix 100% CPU Usage - Windows 7?

Specs:

Computer: Dell XPS 8300
OS: Windows 7 Professional 64x
CPU: Intel Core i7-2600 @ 3.4 GHz {NOT 2600k}
RAM: 32 GB
HDD: 1 TB
GPU: AMD Radeon HD 6450

Note: I do run a Minecraft Server on this computer. The server has 20GB of RAM deticated towards the server.

Basically I just need to know how to reduce the CPU usage because the server I run always errors such as, "Can't keep up! Did the system time change, or is the server overloaded?". I feel the reason I get those messages is simply due to the fact that my processor is really getting bogged down, which I can tell by the 100% CPU Usage. Please help!

  1. It would help to know what process is using your CPU time?

  2. Well I belive a big component of why the CPU usage is so unbearably high, could simply due to the fact that I am running a Minecraft Server off of 20GB of Ram. Do you think that would have anything to do with it? If not, I can tell every process that is going on that makes the CPU usage so large.

  3. Just sort by CPU usage; odds are one or two processes are responsable for the CPU usage.

  4. It quite probably is minecraft. It can happen when you make too large a change using worldedit. But I thought Bukkit was still single threaded. Then again you might be running a vanilla minecraft server, which I believe is multithreaded. I would still check your processes to see what's happening.

  5. Yes, I am running on bukkit. Obviously the big thing eating up the CPU Usage is the java in which ranges from 60-90. There is a another server that has no problems and they are running it on the same system. Does this help? By the way thank you all for your input.

  6. go into control panel

    click on java

    then up the top of the page click java

    then hit vew

    then you put in the number of cpu you want it to use then hit save

  7. I was having 100%CPU usage problem now and then.Though I close all programs before closing down, When I shut down the computer there used to be a message " waiting to close down the programs that is running"But now it is solved.Thank God,I believe that he only helped me to solve it .No other could help me nor am I an expert.I don't say that the problem faced by me is yours as well because this Problem can be due to other reasons as well .But you may try this .Any way this is a very safe method also.This applies only for laptop etc: and not for desktop. After shutting down the laptop remove the battery and charger plug .Then press start button just like for switching on the laptop and hold the button for 10-15 seconds. Computer will not start as there is no power but it can remove the problem (This is jut like removing the battery in mobiles when it hangs etc: ) After that again place the battery back and start it as usual.This helped me .Though I have 4GB Ram i was facing problem. Now it is fine.May God help you .

  9. Taking the battery out of my Dell laptop for a few seconds and replacing it fixed this problem!

    So strange since I had already powered down several times and tried other things like doing a system restore. Nothing worked until I tried this.

    Thanks for sharing!

  11. I un-installed the CyberLink YouCam software from my laptop and the problem went away. I don't have the problem on my desktop machines.

  13. Type in services.msc in start menu and turn off superfetch and Windows update and Windows search if there is such a thing.

    100% CPU USAGE issue — Always prefer the MINIMALIST APPROACH if it works

    Tried this simple something from mastershand and it apparently worked!

    1. shut down laptop computer
    2. unplugged #1 battery and AC adapter jack from computer
    3. pressed Start button
    (nothing, of course)
    4. reinserted adapter jack into computer
    (but not battery)
    5. pressed Start button
    (computer starts up)
    6. launched Task Manager
    (typed taskmgr.exe in Start Menu search field, click on result)
    7. observed dual-core CPU usage under Task Manager's Performance tab
    (lo and behold, 2%-4% – normal!)
    8. re-inserted #1 battery while Task Manager is running
    (suddenly left-side CPU spikes up between 90%-100%
    9. removed #1 battery a second time
    (left-side CPU usage instantly drops to normal)
    10. inserted #2 spare battery
    (CPU usage remains normal @ 2%-4%, a good sign for sure)

    ...but to test for a possible "reset anomaly"

    11. removed #1 spare battery a third time
    (CPU usage stays at normal)
    12. reinserted #1 battery for second time
    (CPU usage remains normal @ 2%-4%)

    ...now, just to take it a step further

    13. shut down computer for cold reboot
    14. unplugged AC adapter jack from computer and cord from wall
    15. plugged both ends AC adapter back in
    16. pressed start button
    (computer starts up and a minute later all still reads normal)

    Once, a disheveled bum in Radio Shack advised me to disassemble my malfunctioning electronic organizer, dust everything, and then reassemble it. Worked like a charm! My guess is that mastershand is no disheveled bum but has the smarts to toy with the ancient tech-maxim to first test the cables. Sometimes, it's just plain physical. — Keith Halonen
