thanks you for your answer.
i forgot to tell that, a few weeks after i buy the PC (about final year 2003), when i did an update of a driver, the 2D scroll in windows gain an incredible performance.
also, 2 years ago, when i went to a technical service for a problem, for casuality they did change the IDE cable between the HDD and DVD-ROM, and, magic!!, the problems dissapears (the HDD cable must be bad..)!!! but,not at all...for games that donīt have a lot of polygons or detail textures, it run perfect, but when i run games more heavys the problem continues equal.
it happen with all the games...: Motogp3,Revolt (an old game),ratatouille,pirates of caribean demo and a lot of games than i try...
i think that the problem could be the Ram memory or the IRQ of the graphics card...
when i buy it, i put a geforce 4 ti 4200 128mb ddr (but while it arrive from the provider, they put a 3dprophet 4500 and it ran better than the Ti 4200 in allmost all the test that i try!!
)
now i have a 7600GS 256mb and the problems continues, i thing that could be a problem of Nvidia with my Ram memory?? i donīt understand yet why it show 99FPS (for example), and to the eyes, it seem like 10fps!!
