You lost me at about 2:20 in. My computer has severe lag issues when I boot up, and play ANY game that uses DirectX for about 10 minutes. Rebooting fixes this, but having to wait for my computer to start up twice each day is very irritating. All what I know that causes this is "SystemInterupts" a process that I have no clue what it does, but I have a strong feeling the problem is with DirectX (Versions 9 through 11, doesn't matter which one). Where can I go to get the latest version of DirectX?

@SianaGearz found the problem now, i opened task manager, clicked show processes for all users and found a system process who took 50% of my cpu usage, i ended it and now it works fine :)

@TheZnukez Don't see exactly what the problem is. You presumably have a dual core CPU and have software which runs primarily single-threaded, thus it's limited to 50% of your total CPU's capacity, which is quite common of software which isn't optimized. Whether that's too much (i.e. you feel this software should not be consuming much CPU at all) or too little (i.e. you feel that it should be able to consume more than one CPU core), is something that needs to be examined on a case-by-case basis.

hey, my prob is... when i look into processes, all of my programs says 00 cpu usage, except when im running any big programs, and my cpu usage is still about 50%. ive done a defrag, disc clean and searched for virus but nothing helps, you got any tip about that?

How did you launch your command prompt like that, and can it be any command prompt?

Hey there... thanks a lot for this tip. I as many others have had that 100% trouble.. it seems to be linked to firefox but someone was mentioning IDT audio codec, which seemed to help. either way, if this happens again, now I will know how to approach it. Great stuff there mate! :)
