Good evening everybody.
too happy tonight because i've solved a long time trouble with SLOWDOWN.
i'll try to explain but be patient for my horrible english speaking.
since i've bought my notebook i've had trouble with OS, first with Vista (ultimate 64) and after with Seven (some alphas, betas, release candidate and rtm), always the same:
after working for some minutes/hours the desktop and the windows refresh become slower until no possible use, the only solution -> reboot
after the reboot the system performed smooth and fast until the inevitable slowdown.
i've tried EVERYTHING, register clean, virus clean, worm clean, defrag, but everytime the problem popped out again.
read many posts here and i truly hope that what i've discovered now could be of any help to you.
installed with the drivers
of my notebook, there is a tool for enable 3 buttons for open the browser, email and another chooseable tool, this program starts with the OS and launches another .exe that displays a writing on the desktop saying what button you've just pressed.
its name , in my case, was OSDshow.exe
this little b**tard probably had something like a very bad garbage collection, so using these non standard keys, in any way, it was filling video memory with trash.
when using the task manager i've tried to close some of non windows process active, just when i've closed it the desktop refresh sudden started to perform as the system had just booted up.
if you have an overtime system slowdown, try to disable one process at a time, and try to do windows opening/closing, you should rapidly find the guilty one.
truly hope to have been of any help
