Hello,
I have Window 7 Home premium 64 bit
has 4 GB 285 total GBs.
Uh,,I dont know why, but my cpu usage is running at 100 percent, and this laptop is really new, only few month old. i didnt download anything on my laptop either o_O except some pc games and i already uninstalled them.
i even checked task manager and see whats running, but nothing is running except the IMVU(its a chat) but it says imvu is about 20 percent to 30 percent. but my cpu usage is at 100 percent. please help >_< what do i do to fix this. this is pretty annoying >_<

Tick the box which says "show processes from all users" when in task manager that will tell you whats running high, then get some anti syware apps and run several scans and run some anti virus scans also.

on the task manager it says NONE. but cpu usage is at 100 percent o_O
for example, i open pet society on facebook, cpu usage becomes 100 percent.
i open messenger. cpu usage becomes 100 percent. the thing is thats only thing im opening. to fowang.

Task manager does not report everything running. Try downloading Process Explorer http://technet.microsoft.com/en-us/sysinternals/bb896653, it's free from microsoft and will show all the normal stuff plus DPC (Defered Procedure Call) which is a possible culprit in this case.

If you do have your DPC using loads of CPU then it's normally a bad drive or resource conflict.

CPU RUNNING 100 PERCENT UNTIL TASK MANAGER OPENED SOLVED ----- All of a sudden my computer once started would run at 100 percent CPU and the only way to bring it down was to open task manager//// This worked for me, after running numerous scans in safe-mode to no avail, I did this....There was indeed a virus on my PC and I found it by going to Control Panel - System and Security - Fix performance issues. When I ran this scan I noticed two files in my startup folder that were not visible in Task manager. One was Yorkgroup which I am assuming is the YRK virus and the other was the CRSCC/csrss virus..... I disabled both and my system runs normal again with CPU back at 1 percent..... This link may help as well http://www.tomshardware.co.uk/forum/7700-63-csrss-description-image-path

As stated before, in task manager, show all processes and sort by CPU. This happened to me before and it was because of a virtual machine instance. Once I closed that instance the CPU usage dropped back down to normal.

I disagree, an average computer user would not setup a virtual machine on their PC, if they do then I would consider them an intermediate user, who is not using the PC for everyday normal use like surfing and emails ect. Anyone that setup a virtual machine, this would be the obvious culprit. So If you have not setup a virtual machine then this cannot be the reason and the more likely reason would be a virus like I had on my machine. I am running a Mac with Windows on bootcamp but this does not run virtually it runs natively. If anyone reading this post does not know what a virtual machine is, then dont worry you dont have one running!!!!!
