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.

Just wanted to update on this issue.
Pulling a plug out a little bit, just so the DPClat starts to show green bars isn't a permanent solution.
Because once you shut down or put your laptop to sleep mode, it somehow losses power cable, like its disconnects by itself.
So you come back the following day and battery is drained, so you need to actually repeat this overrun procedure every time you load your system.
-put the plug all the way in, so your DPClat starts showing green bars
-after like 2 minutes your laptop starts jerking and lagging, at the same time DPClat turns RED
-no the procedure: very gently start pulling the plug, turning left right helps a bit, tiny slightly little bit by bit , stop every second and constantly observe your DPClat, once its GREEN... GET BACK your filthy fingers from that power plug!!!
Well done, you can work now, the battery is charging, all good. But remember, once you shut down/sleep your computer, you need to repeat the above procedure.
