General Low Performance (without gaming)

I removed kaspersky, installed microsoft security essentials

but nothing changed, still there is a periodic glitch or slow performance for seconds when I open any program or even the explorer
also videos in low quality are slow (in video playback but the audio is ok so they are out of sync.)
and the flash videos are very slow

Well, is there anyone who managed to solve this problem or even spot the cause of it

My friend installed the same windows on his HP Pavillion notebook and he has no problems even with Aero themes

every thing is smooth and fast although his notebook is weaker than mine

I agree, you must have either a bad driver installed, or a background process that's using a hefty amount of resources.

If you can reboot the machine, wait three or 4 minutes then make a screen grab of the full process list in Task Manager.

Some of the nVidea graphics add-ons can be a cpu hog but not to this extent.

Might want to download the DPC latency checker, very simple tool, does not alter your system in anyway, doesn't even write to the registry.

DPC Latency Checker

thanks for the reply and the program
It says that there are some device drivers behaves badly

I will try its solution and I'll get back to you

first of all this dpc is a wonderful program I managed to solve half the problem i think

the pictures here is before and after I closed this Intel(R) ICH8 Family PCI Express Root Port 2 - 2841

it dropped the latency and the videos playback is normal again but not all the latency is gone

still there is a stupid process that occur rarely but it pumps the red column very high

and also it closes wireless and wired internet connections so I can't close it forever

what should I do about it?
and how can I find the other one? I tried all the devices and there are couple in the System Devices that require restarting the computer so I didn't do them yet

By all means, restart the computer, in fact, most of the time it's recommended to do that after every change... tedious, yes! But it will help isolate the problem.

My other suggestion and what helped my Desktop, make sure you're running the latest BIOS.

Also, even though the DPC docs mention "Drivers" as the main culprit, it can also be background processes that chew up resources and/or cause conflicts.
If you can, post the list of background processes running, peer to peer networks often cause problems as well as too many "junk" extras running in the background.

I use this machine for recording multitrack audio sometime between 8-12 tracks at once so I've tweaked quite a bit to reduce DPC latency.

What can I do about the drivers that is causing the problems ?
for example the Intel(R) ICH8 Family PCI Express Root Port 2 - 2841
the computer tells me that its up-to-date, so what can I do?
