I recently installed a new AMD Athlon XP 3200+ 2.2ghz processor, a-bit nf7-s2g mobo, 768 mb of DDR400 PC3200 RAM, and my computer is constantly locking up and i constantly get a blue screen which vary, but all tell me to disable memory shadowing/caching in memory options in BIOS which i cannot find, if anyone has a way to help please reply! or IM me on AIM @ NobodyLikesMe352.
