Hi there,

I am using Compaq Presario C700, Win 7.

I have been facing a problem of high CPU usage by System Interrupts. At times is 100 % even when i check in Resources Monitor in Task Manager. It LEADS to overheating and unexpected shut down.

At times when i try to start the laptop, it does not start, just a blue screen comes nothing else.

I have updated all the drivers, still have the same problem.

please help me getting this solved if possible.

With regards,
RAVI   What is CPU temperature at TIME of unexpected shutdown?Usually, it goes the other way around.
Overheating may cause high CPU usage.I did not notice the temp at the time of unexpected shutdown but at time its too hot that i need no heater at all.

I understand overheating causes high CPU usage but CPU usage in this CASE is high even after 5 mints after starting the system.

thanks Download System Information for Windows (SIW free version)
No installation required.

After it scans your computer, navigate to Hardware>Sensors and post all info from there.

thanks for the reply, please find the required information........

king regards,
Ravi

Max temp for your CPU is listed at 100C, but you can't be getting so CLOSE with idle computer.

How old is it?
Still under warranty?no its not under warranty....... age is nearly 2 years old.

can we fix it or its just gone its very loud and speed is bit slow tooOverheating does it.
Get a can of compressed air (do NOT use anything else) and clean well all vents.
Re-run SIW and see how it goes.its too late to go to the market to get a can of compressed air.. will certainly buy in morning and let you know .... thanks and good night This is not your make & model of notebook, but this is probably what's wrong.
