He then installed everything necessary, but since then monitor shows only 24-bit colour depth (max available). My monitor is LG Studioworks 563N 15". I have Intel 810 motherboard, 40 GB Samsung HDD, Celeron 1.0GHz Processor, 256Mb SDRAM. I have 98 on c: & win XP with SP2 on d: Please tell me solution.
