Be careful how you interpret this information. In general, any program that has "work" to do will use the CPU when it is available. Showing 100% CPU usage over en extended period of time MAY indicate a problem or it may just reflect the case where there are background programs beiung run that have no effect on the system. The "scheduling" iof the CPU is usually done in chunks called quanta. Since CPU time is usually scheduled on what is called a pre-emptive mode, lower priority jobs (like virus scanning of the disc) will be pre-empted by an interactive user command (word processing for example).

Without examining your system and understanding what programs are running, it is hard to provide guidance on how to "fix": the system. Use the task manager to see what percentage of time is being used and for what. The utilization is shown as a percentage of the whole. Report the info here and we should be able to at least explain what is happening.

My dell is too slow even if i am playing computer games. why?


Your Dell laptop has low RAM/high CPU usage, a lot of games tend to use high CPU, so your laptop could be a little old for newer games, so you should upgrade it, or you have a lot of files on your laptop and maybe you opened to much high CPU usage programs.

Slow internet, gaming, everything.


Try Chrome browser, but Windows based systems tend to slow down with time. Specially with older and slower systems like mine. Try disabling startup processes. In Windows Start > Run (search in Win 7) type msconfig. Go to Startup and disable anything that you don't require to start. They will kick off only when you run the programs instead of utilizing resources like memory and CPU for the get go.

My Toshiba satellite pro M10 very slow.


check your system performance thru task manager. check for CPU usage. usually COU usage is 1% to 10%. if your CPU usage would peak from 10% to 100% there is a huge possibility that there is program running on your computer that eats up your memory. Or it could be spyware/malware

Procesor usage upto 55% wen having opend single window


could point to both hardware and software issues..
but first check software issues. can be due to virus/spyware running.. check taskmanger and lists the processes by cpu % ... this will give you the process which is gobbling up the cpu cycles. make note of the file and track it down in hard disk. you will then have to research what it is for.

if you have a antivirus installled it may be possible that it is virus scanning the disc.

hope this helps

Dell Dimension 8250 PC running Windows XP SP2 has CPU always at 100%


I guess it could be a virus, avast is not the best antivirus in my opinion, try to get a norton antivirus or NOD32 update it and run the scan, it ocuurs when a replicating virus copies files to all your HDD and is always busy...making system busy...and one more thing there could easily be a copy of the virus in your pen drive as well...
