agan" mau tanya nih, kq driver v sm vga card ane ga sesuai ya?

Spek pc ane :

mobo : ecs
chipset : geforce6100pm-m2/nforce 430

vga card : axle radeon HD 4650 512 mb

Ram : maestro 1gb pc 6400

5hr yg lalu tiba" driver vga ane unable, trus ane coba install lg pake driver pack solution 13. nah display adapter ane yg tdnya kebaca ati radeon HD 4650 eh berubah jd geforce 6150SE nforce 430 . dan memorynya jd cuma 256 mb
