I have a HP Pavilion dv6 laptop that is running on Windows 7 and is a little over 2 years old. Often it, for no good reason, starts to run at 100% CPU and makes doing anything impossible. I was wondering if anyone had any ideas why it was doing this or what I could do to fix it.

Do you mean once Windows desktop is loaded? Any start-up programs automatically opens and have you checked what process runs high on task manager?

It only happens once I've been on my computer for a while. When it happens I open up the task manager to see what is taking up all the CPU and when I go to processes the thing at the top using the most CPU is the task manager.

Well I wouldn't worry about that anyway. If its for once or task manager is the culprit. Do you notice any performance lags or slowness?

No lags or slowness. As far as I can tell it runs fine until this happens. I could be just surfing the net and then it will start to lag heaps and I look at my CPU meter and it's at 100.

Multi-tasking is bound by what hardware specs you have. So, if there are multiple programs, browser/windows are running, the CPU will jump to high usually as the software requires to run. Another cause would be infections or cache files stored. Have you tried clearing junk files and scanning your laptop with free Superantispyware and Malwarebytes together with your antivirus? What protection softwares are installed for your pc? Sometimes thermal events could be a big factor.

I haven't tried to use Superantispyware and Malwarebytes yet but I shall try that now. I use AGV antivirus.

I used Superantispyware and Malwarebytes yesterday and the problem is still there. I have already used Ccleaner as someone else suggested to me to try it.

My computer is never slow or lags until the CPU goes crazy. When that happens though, it just lags really badly making doing anything basically impossible. I hope this answers your question properly.

What programs are running usually? Both offline and online activities? Have you considered checking on hardware temps. since this is a laptop?

Usually Chrome, VLC, uTorrent, Flux and Rainmeter are the things that are running when the problem occurs. How do I check the hardware temps? When I have run Defraggler it says that the temp is good. Is this the same thing?
