Via iHyperion ins. Problem
Man u use a very old package.I have kt333 not kt400 but i use Via Hyperion 5.09A ,it works good for me,this package has included a newer ide driver(better performance) with origins in that ide accelerator(old and unusable),also has the last Agp driver ,a newer one than the one in 4.42 package.U can try 4.51 ,4.55 or 4.56 also(they dont have for ide the updated driver). Instability issues on kt400 are solved with AGP speed set to 4x and fast write turned off.Try also another ATI driver.Unzip one of the packages and update drivers manually or make a clean install for testing.For me Via Hyperion 5.09 is stable and works better than Via 4 in 1 4.43,try it.I use 5.09 downloaded from my vendor MSI ,see if on Soltek website they got it, or just try the one from Via Arena,all packages seem to scale good for all chipsets.Good luck!
