My computer cpu usage also increases upto 100% very frequently due to which my networking becomes quite slow.

I downloaded the Hijack program and came up with this log file.
Please help me out....

Did you run this temp cleaner, but you didn't answer my question, no antivirus running? The hijackthis log looks clean

anti virus

I am using anti virus Nod32 and no other anti malware,

I re-installed the windows but then even the problem was not fixed,

I ran the tool you prescribed but still no solution.

May be overheating. Do you have a simple laptop cooler platform?

NO Laptop

Well I do not use laptop .It was the other guy having laptop.

I use pentium 4 pc with 768 MB ram , 2.40GHz processor , 20 GB hard drive and desktop system of dell (model: GX 260).

Now what?

Open task manager and see the process with 100% or big numbers
It won't be hard ;-)

dont know

I do not have a idea how to have a look at the percentage used by the each process.

Please guide me.

Type Ctrl+Shift+Esc. Click the "Process" tab

Done ;-)

task manager

Processes tab shows the details as:
Now which bar shows the usage , the CPU one or the Mem Usage ?

just look at this picture and u will understand

Usage

Well then the system idle process is using up all the memory. (i.e >80)

So now what is the solution for this.

No no no, System Idle Process is... well nothing.
Your cpu is 20% used. System idle Process says how much in % your CPU is not used. So if it is 99% it means only 1% is being used. See the others except the System Idle Process and tell me ;-)

Its the running program

Then I can not tell specifically that which program is using the memory because when system is at rest , the cpu usage is normal but whenever i run any program(eg. open google chrome or a website , play cs or watch live streaming) the usage of that program increases to 90 above and then constantly falls to around 60%.
If the program is closed then the cpu usage comes to normal.

Hence the running program takes up all the percentage usage.

I hope this helps.

Could you please post your system specs?

system specifications

I have already mentioned it above .

I use pentium 4 pc with 768 MB ram , 2.40GHz processor , 20 GB hard drive(out of which 9GB is empty) and desktop system of dell (model: GX 260).
I have Windows Xp (Sp3) installed.

I don't really know what's going wrong.
Well , 20GB is way too low but I guess that is not a problem.
The Computer seems to be very old, open the case and remove any dust you find. Also upgrade ram and cpu.....
I don't really know what's going wrong :-(

In the days of the old Pentium 4, and 20GB hard drive computers we never worried about CPU usage. The 100% CPU usage is really not a issue at all with this old hardware

These "old days" are over.
Now people make programs for better hardware, hence more speed, hence slower speed on old cpus :-(

Well I have been using this system for 3 years but have upgraded it along the period.
This is the first time I am facing this problem.

Well Thanks for your help.....

By the way what system specs would you recommend after this as I am planning to take a new PC.
