hi everybody,

i'll go right to the point, when i start the game (GTA IV), the first screen apears but it stop there, it doesn't change, then the message of "searcha solution online and close the program" or just "close the program" (i have windows seven). I also have problems with other games, like low fps or slow gaming...

i have a:
HD5770
Phenom x4 945
Mother Gigabyte Ma785gpmt-ud2h
OCZ gold edition 2gb (x2)
Power suply Vitsuba san-70.s
Mi HDD is 6 years old (western digital, i don't remember the model name...)

i realy don't know which is the problem, and i'm realy desesperate...

Thanks for reading...
