video card, modem, memory stick, hard disk i tried changing all of those components, i also bought new ribbon wires for the connection of my hard disks and cd/dvd driives, after that i formatted my computer but still my computer freezes, one of my friends told me that i should update the bios of my mother board, is that ok too? also i tried removing both of my cd/dvd rom drives, but that didn't solve the problem..
