Could you help explain to me, why my processor run on 40% or higher even on Boost stage after i used my laptop in for an hour
i always notice on my ready boost gadget that it is always on boost stage.

my proccesor specs

Intel core i5-480 M 2.66 GHz
ready boost cache up to 2.93 Ghz

i also hear that my fan is consistently running on speed as if i was playing a game

can you guys explain to me?
why my proccesor is needing such speed even i was just surfing the net,..

thanks

This is usually the sign of something running in the background. Run Malwarebytes (from malwarebytes.org) to make sure you don't have any nasties running on your rig.

Good luck!

Open Task Manager (ctrl+shift+esc)
Select 'Processes' tab
Select 'Show processes from all users'
Click on the CPU heading to list highest cpu usage at the top
Note the culprit with highest CPU usage

Once you've done that look up the whatever.exe online to see if it's trouble

you might have some programes running at startup
got to start type in the search box "msconfig" and enter
then click on the startup tab and untick all the programs that you dont need but leave the ones like "microsoft something" or "intel something" and the apply and reboot, it should be better now.
if it still doesn't work, then backup all your files and do a factory reset or reinstall windows

The problem most likely lies in the fact that you probably have a virus, usually the common symptoms of a virus are increased CPU usage when simply sitting at the desktop. CRTL+Shift+ESC, and check your processes listed by memory/cpu usage, if there is an unknown high usage process running that is most likely a Virus. If this is not the case your CPU could simply be getting old and used up, there also my lie a problem within your cooling due to the inefficiency of laptop cooling. Your CPU fan might be shot which will cause overheating, which will then cause a lot of problems. This is very common in main-stream laptops (majority of Laptops), anyone whom has asked me what the problem with their laptop is overheated due to the death of their CPU fan. I believe its a common fix and a local Computer services Store could help you out. Also I suggest in investing in a cooling pad because they very much increase the lifetime of you Laptop. I hope this has helped you in some manner!

the i5-480m is NOT outdated at all and is a decent mobile cpu although it is a model that tends to be a bit hot.
his cpu fan is not dead as the op already said they were just running at a high rpm, though it might be just his air vent/fan is clogged up with dust, he should see and clean it then it will run cooler which results in a drop in noise level

Congratulations, it's a virus.

svchost.exe is a common place on how virus tend to disguise themselves.

Run some light antivirus app for first treatment, something like ANSAV, Norman Malware Remover or something like that that does not require installing. After that, you can decide yourself whether or not a full antivirus software is needed.

Get this:

Burn to CD. Then boot from the CD and complete a full scan of your system. This tool is free, reputable, and highly effective. Remove all the crud it finds.

ei guys, i tried all your suggestions but i didnt find any virus on my system... anyone of you know about the UPnP service? thiing fix does work. i disabled it thus this thing causes the svchost.exe to make my CPU run wild at 99%...

this is what i did..

1. when my CPU is at high. i open up task mnager and on processes tab i click on show processes from all users

2. then i see there that svchost is at the top. then i right click on it and go to services.

3. then on the windows that appeared i find out some highlighted services. one of them is the upnp host service.. tried to stop and start them 1 by 1

4, then when i stop the upnp host service, my CPU usage suddenly drop.. then i disabled this process to keep this from starting from boot up..

5. before i did that i research the web for some risk that would cause system break down.. just a precaution...

this migh help for some.. for others kindly give some comments for this action.. thanks..

i used to have this exact problem with oem computers, but i have never had this problem with computers that i personally done a fresh oem-crap-free install of windows, but this problem can be solved by doing a factory reinstall, but if you have important stuff on the computer then you will need to backup your files

Sounds like a bad driver possibly, try updating all of your PnP devices drivers.

its cool to post your solution and the steps you took, not many do.

it looks like the uPnP service is for looking for shared devices on a network; printers, scanners and such. if your not on a network then it is unnecessary to run it. maybe thats why it was going all flonky, looking for something that wasn't there . . .
