High CPU usage (100%)

[jhonwds]

Hello guys,

Its been like 1 week that my PC is acting unusually. I have a HP Probook 4520s 2.53 ghz 5 months old. There are times my PC hits high CPU usage 80-100, non-stop. I did many things to try fix that like:

1st. Used like 3 programs to check for viruses adware etc, and nothing.

2nd. Defragmented my Local Disk.

3rd. Used CCleaner.

4th. Did Disk Cleanup.

None of this actually worked.

I have recently noticed that when i plug-in the charger my PC starts to act slow. I tried 2 different chargers (My cousin had the same PC) and this still happens.

Please help me if theres any way to fix this (even with format of everything) rather than sending it to service.

Thanks in advance,

Marios Pastos

Determining what's utilizing the CPUEach process that is running in Windows and the CPU usage it is using can be determined by opening the Windows Task Manager and clicking on the processes tab Once this tab is open click the CPU button above the list of programs twice to organize the programs CPU usage from highest to lowest. 

Permanently keeping the TSR disabledIf you've End Tasked the program following the steps above to temporarily remove the program from starting up but it returns each time you start the computer you'll need to disable that program from starting each time Windows loads. 

Computer Trojan, Virus, Worm, Spyware or other malicious programComputer Trojan's, Viruses, Worm's, Spyware, and other malicious programs designed to destroy or modify data on your computer or other computers attached to your computer or designed to attack other computers can utilize your system resources. Make sure your virus scanner/Antivirus is up-to-date.

So, I have a sort of strange problem (I think). I have a fairly new HP ProBook 4520s laptop (its almost a year old) and with Windows 7 32bit Ultimate, a few weeks ago it started doing what is said in the title. When the battery is running low and I plug it into the wall, it becomes very slow and shows very high CPU usage (fluctuating, but somewhere about 80-100%). It does this even if I close all programs which were open and just leave it alone. I've tried to use the Task Manager to see if there is anything in particular causing it, but nothing in particular shows a high CPU usage.

Note: I don't make any cheange to my computer.

I would really appreciate any help!

I had the exact problem with you mar-rih and I found out that it was the battery's problem because when it was low on battery it didn't give the processor the electricity it needed so it was becoming really slow. Remove the battery and test your computer again, might help.

hello jhonds,

i'm having the same problem the reason could be the air blocked, due to a lot of PC dust ( dirt that build up over the time ) you can take it to specialist to clean it for you, or you can do it your self with help online,

go to START>CONTROL PANEL>under the system and security click on FIND AND FIX PROBLEMS> under the last one SYSTEM AND SECURITY run all of them, Fix problem with windows update, and Run Maintance, and the other two, if that didn't fix your problem then take off your battery and let for few seconds/minutes and put it back in, if that didn't work too, then double click on battery on the bottom right>HP power Manager and change it to High Performance, that should do it, also download Advanced System care and open the toolsbox,  Under Optimize section open Startup Manager and Disable the Optional stuff that takes high CPU usage, DO NOT DISABLE ANY NESSESARY THING, and i recommand you to look up stuff that you want to disable and see what they do before disabling them if you have no idea what they does, Hope this helped
