Windows 7: CPU 100 issue

Hi Everybody,

I am encountering a really annoying issue with Windows 7. Whenever I start using a lot of programs simultaneously then the CPU of my laptop will go to 100% and it won't fall back to it's regular value of around 4-10%. Even if I close all the programs and end a few processes, the CPU will stay 100% and my CPU (ofcourse) get's really warm.

When I reboot the system, the problem is still there. It only goes away after a while when the CPU is cooled down, then my system operates normal again but as soon as I start doing something (e.g. yesterday I installed the driver for my videocard,during the installation) the CPU goes to 100% again and the same problem happens.

This problem happend 3 days ago when I was still running windows vista. I had the exact same problem, but in win vista the CPU was 100% everytime I turned on my laptop. This never happend before, so I did a system restore in Vista but the problem was still there. After that I scanned my system with an anti-virus (avast) and anti-spyware (spybot) program and that did not solve my problem. I did some research on the i-net saw that a few people experienced the same problem, but all of them had different reasons that caused the problem and also different solutions. I chose for a clean install of win 7 (I was about to do that anyways). But it didn't help me.

So after performing a clean windows 7 install the problem is still there My CPU goes to 100% and I really don't know how to solve this annoying problem. So is there anybody out there who can help me solve this issue?!? I have a HP Pavillion DV6700 laptop and you can find the specifications: HP Pavilion dv6700 (Core 2 Duo T8300 processor 2.4GHz; 2GB RAM) Specs - Notebooks - CNET Asia here.



thanks in advance,

Hi and welcome

If you had the problem in vista and win 7 it is n ot the operating system. It has to be hardware. could be Heat related, memory related, etc.

You dont have a lot of ram to begin with so I am sure that isnt helping but dont think it is the primary problem

Thanks for your reply Ken J,

I forgot to mention that my laptop has one extra gb of RAM, which brings the total amount of RAM to 3GB. When the problem happend and I looked into my windows task manager. The memory is around 888mb (not quite sure what that means, but I assume it uses 888mb of the 3GB?!?).

Since you say that it is probably hardware related, I have to mention that my CPU fan was making a lot noise when I was not even running heavy programs (just surfing the web, checking my mail). So my housemate said that it was probably because the CPU fan was covered with dust. He cleaned it by holding a vacuum cleaner against the laptop (CPU spot). Everything was uncoupled, no power supply connected and the battery was out. After that it did not make that much noise anymore, my problem started 2 days after my housemate used the vacuumcleaner. Could that be the problem?

thanks in advance,
