[The problem] :
Regarding the overcloking, the system cannot manage the agp bus.
if the agp fastwrite , agp read and agp write are enabled in BIOS the system becomes unstable and in games is freezing (including counter-strike 1.6 ver).
if the agp fastwrite , agp read and agp write are disabled the system is stable but pour 3d performance (9 FPS in doom 3 [with medium settings at 640*480 , all special FX on , ] on geforce 6600 overcloked )
If the videocard is not overcloked still the same problem.
Scanned for viruses/spyware/etc and none found.
With the hyperion driver the problem becomes worse.[the system is freezing without entering any game]
The latest nvidia driver do not solve the problem.Has no effect.
