Laptop CPU 100% Usage and at HIGH Temperature

July 6, 2010 at 08:26:11
Specs: Windows Vista Home Premium SP 2

Hey, my Vaio has been acted weird lately.
When I just turn it on, within minutes the
CPU's temperature is at 60+ degrees Celsius
and the CPU Usage is always at 100% all the
time. I ended processes I don't need and stuff,
and in the task manager, if you total the CPU
Usage of each process then it adds up to 40%
max, however it is displaying the CPU is
100%!! I ran scans with AVG and Windows
Defender and nothing was found...Idk this is

There is no connection between running programs and cpu heat. It would appear you have a hardware failure as in your cpu fan has failed. I would suggest taking it to a shop for repair or if under warranty contact Sony

Well, I scanned in safe mode..during this time the CPU
Usage drops to 30-40% and it's normal...when I startup in
normal mode, the temperature increases as well as the
usage. It's now between 80-100% at all times. I am running a
scan with Spybot now, it has been recommended by one of
my friends and it's finding traces of malware and trojan.
I have been told that it has to be a virus, but I will get back to
This PC has been bought in November, chances of
the CPU failing within a year is very odd...very, very odd.

not cpu failing but either a lack of airflow over the cpu [fan failure] or other heating issue [clogged/blocked vent]

When in Safe Mode the temperature and the CPU usage drops.
The temperature is around 40-50 degrees Celsius and the usage
is at 20-40%

When in Normal mode, the temperature is in the 60's and the
usage is up to 100%...near constantly.

Do you know which process is taking the most cpu usage ? Open Taskmanager and click processes tab. Also click show processes for all users. Now you can see what it is that is consuming most cpu cycles.

Here are the processes:
SpybotSD.exe*32 42
YahooWidgets.exe*32 13
Rainmeter.exe 05
Taskmgr.exe 02
Chrome.exe*32 08

There are other processes but the CPU shows 0% taken and
at the bottom the Usage is set at 100%.
This is just near constant. My previous search with Spybot
found 3 threats, 2 were removed. Spybot asked to run at
startup because one was IN MY MEMORY! It scanned for
about 6 hours and nothing was found...I fear the third virus is
still there...

Those processes total 70% cpu usage.

SpybotSD is taking 42%.

SpybotSD always finds things, tracking cookies, etc. They may not be harmful.

I suggest you to end SpybotSD. Is it SpybotSD or should it be SpybotS&D search & destroy ?

By the way, 60 deg C is not too high for notebooks because the environment is too tight for them.

My Dell Latitude D505 with WinXP is now at 48 deg C when I am just typing this post. Nothing serious.

" displaying the CPU is 100%"

Are you talking system idle processes?

You need to differenciate between a overheating issue and that of a malware infection. You are making them the same thing like malware is making your cpu run hot. Doesn't work that way.

You can run your car at idle or at 100mph, and if everything is working as designed, your temp will remain within normal params.

BTW malware is always found in memory. That is how it can operate. Doesn't do damage if it just remains a registry hack or a file on the disk.

Try malwarebytes to scan for malware. I have found it to be better than Spybot.

The CPU is always at 100%...just near constant and at this
time I'm looking at the taskmanager, the YahooWidgets is
using the highest 13% of the CPU, while 7 other processes
are using 6% and less. Yet, the CPU is 100%...The Math is
simply not right, and I will scan for Malware.

My point here is, there is no process using a significant
amount of CPU space, the maximum currently is like 12%
and not a lot of processes are active. It has to be some form
of malware or virus, right?

I have found a service "avgchsva.exe" using almost 50% of the
CPU, now I am thinking it is related to AVG. I have tried to end it
several times but it keeps popping back up.
Another process is System Idle Process and svchost.exe which
both use high proportions of the CPU and I know that they both
are important...How can I get avgchsva.exe out?! When I need
AVG then I will open it.

avgchsva.exe belongs to AVG antivirus program. I suggest you should use mse (Microsoft Security Essentials) to protect your system. In my opinion, mse protects you much better than AVG. Plus it uses less resources.

system idle processes runs at 98% most of the time. This is normal. It literally is a counter that says the cpu is doing nothing but idling.

Not a single thing you have posted concerning processes is abnormal.

After reviewing notebook/laptop average temps what you are seeing is normal.

But the computer is rather laggy...and I have hardly encountered
such high temperatures before. When I add up the CPU usage of
the running processes it's not even near what is displayed as
100% CPU usage. When I add up the usage of the running
processes it comes out to be like 52%.
Is there another process not being displayed I should know
about? Because as I said, the computer has become slow and
the physical memory occupied at the time is 41% and I have 80
GB free.

How much ram do you have?
When was the last time you ran disk cleanup and defragged the drive?

You need to understand what you are seeing in task manager. First you need to check the box for show all user processes.

You will notice mem usage, peak mem usage
Memory usage is dynamic which means it constantly changes. This is also why adding doesn't work. Mem usage is current. Max is when it was busiest.

The important column is CPU. If not running anything they should all be 0 with an occasional spike as a job is performed.
If all are zero you will find system idle processes at 98-100%

I have a 4GB RAM and I use CCleaner like twice a week and I
defragged the drive probably...months ago.

I chose the option to display the processes for all users and 82
processes are running, in which 70 processes are 00 under the
CPU column, and the others are showing small numbers.

CCleaner alone is not enough. I use Avast and Malwarebytes which I have had great success with.

You have plenty of ram so that is not an issue. I have like 65 total processes on my vista laptop [and its running Norton Endpoint - resource hog] so you are in the ballpark there.

Can you describe the "weird" behaviour?

It's just running much slower and on average the CPU heat is
between 44-57 degrees Celsius, now it's between 59-67 degrees
For the past 4 days, it's been acting like this and I really don't
consider it normal
