Hey, I have this wierd problem that makes me throw the laptop through the window.
I have no idea why but the computer gets really really slow after about an hour and the cpu stays
on about 70%-100% usage.
what could I do to see why it's like that ? (by the way I formatted the computer like 2 times and it didn't help)

As an aside~ is it just me that thinks, "why is it that the laptop fan is not made easily accessible so that you can clean the thing"? I mean, it would NOT be that difficult to do. My gosh- there are some laptops where it's impossible to even reach that area without a near-complete disassembly (& about 100 tiny screws of various sizes to lose)- or worse- the ones where you must lift the heatsink from the CPU to get to it!
End of rant~ ;)

Just burn a Knoppix CD (live linux) & boot to/run it. There's a cpu monitor built-in. See if the usage climbs when the hard drive/Windows is out of the equation? Gotta eliminate some variables... :)

I would make sure the heatsink is snuggly against the CPU, as well as the vents clear of any dust or things that can clog it. What environment is this used in usually? (Bedroom, office, etc) Soft surfaces can clog the vents.

first thing, get core temp and run it while the slowdown is happening http://www.alcpu.com/CoreTemp/
then also install codestuff starter and disable any item you don't want automatically starting. http://www.snapfiles.com/get/starter.html
most applications don't need any of their startup entries to function normally. They simply add them self to the startup to give the appearance of a faster app startup since it is already running (even when it is not needed or wanted)
PS you cannot tell how dusty a heatsink is from the look of the outside vent. Compared to a desktop CPU heatsink, a laptop heatsink uses thinner fins that are closer together to increasing the cooling surface area. The down side is that it clogs significantly faster than a desktop heatsink.
Another thing is that certain laptops such as the thinner/ more stylish ones will use a cooling solution where at full load the CPU will only stay 5-10C under the overheating temperature. (For example a macbook pro will throttle if you run mental ray on it if you have not cleaned the heatsink in a few months)
(PS while the macbook pro has heatsinks that are too small (not designed with bust buildup in mind) their overall cooling design is currently the best on the market as the vents are all located on the side instead of the bottom so placing it on a lap wont cause the air intake vent to be blocked and cause high temperatures to reduce the system life span)

Hey, before I do anything I wanted to format the computer to make sure it isn't a software program. so after I did the format here are the results:

just to be clear here on the peice of a Modern lap top which is basically obsolete replaced by ultrabooks, notebooks ..
there is the power lead , charger power supply, battery, keyboard & trackpad , monitor , case, HDD, Motherboard which everything else video card, sound card CD/dvd drive burner, fans , are on board all one part, some laptops have a compartment where you can plug in additional ram others do not . that is it if one thing goes wrong other then the HDD you pretty much toss it out get new because it can be repaired but the bill will run you $500 with the motherboard and bench charges ..
talking to a few people in the industry selling computer and lap tops for years not long ago told me basically there was one company left that was assembling lap tops no matter what name was on them and last summer they ceased making and assembling laptops all that has been sold since is warehoused stock from over supplying a slowed sales once the supply is gone its gone they will be no more , desk top you can still order directly or build your self for now but they not assembling them any longer either anything out there bought today was produced between 2006 and mid 2011 ..

Here's the long and short of it:
What ever it is there is an event or a process associated to it. If you can't view all of the processes you find a way to view all of the processes. You look for errors and warnings in the events. You could even look in the device manager for hardware issues. If you want to fix it you have to dig in and find it.

some people are getting confused between CPU usage and CPU tempurature. from the screenshots you have uploaded your talking about CPU usage.
in the task manager open the 'Performance tab' then open 'resource monitor' (at the bottom of the tab)
Click on the arrow pointing down on the CPU section, this will show all programs that are running and how much CPU usage they are using.
now click on either 'CPU' or 'Average' to bring the culprit(s) to the top, google the process and find out what it is and if anyone else has had the same issue with the process.
If your having thermal issues, download speedfan to see the temuratures, your CPU might be throttling down to cool so is making processes take longer and more CPU usage.
