it is hard to follow completely the actual problem. There are no known generic problems that i know of that can cause what you are seeing
So, assuming the BIOS is up to date, i would install Windows 7 from scratch. You can order Recovery media from HP Support, or you can start with a Windows 7 Professional and enter the license key. I would then install and run HP Softpaq Download Manager (www.hp.com/go/sdm) and install any updates it shows as needed - AS LONG AS they are hardware drivers - NO ProtectTools or anything else at this time. I would also install the Essential Microsoft Windows updates softpaq (Hotfixes from MS). Once you have a clean Operating System, install your apps and verify use
Also, for Windows 7, make sure you enable Legacy mode in the BIOS, unless you plan to install Windows 8 where you shoud enable UEFI mode
Let us know how it goes

i see that most of HP representative doubt in my BIOS
so i will tell you what i doubt in about it
i installed Linux UBUNTU studio 12.10 , can this be a reason for this changement ?
and also i formatted my HD m cleaned my RAM ports and checked the fan > everything is well
i use a good WIN 7 x32bit version with clean DVD
reinstalled it more than once trying to understand the reason for this problem
i downloaded all the drivers of WIN 7 professiona; x 32 from HP official site
created the HP tools partition
i got a rate of 5.6/7.9 in windows 7
any new ideas ?

The issue with latency issues causing huge freezing delays and jerky sound on HP probook laptops is caused by a power supply.
It has an extra wire inside which transmits some data from and into the laptop, and after some time it starts causing problems.
The solution is simple: just pull the power plug from the laptop .. just a little bit, like ~3mm, so that sensing wire gets disconnected but you should still have a charging power.
You can also just pull the plug out, but then you're running only on a battery.
