Toshiba A200-M00, Vista Home Premium, up to date. Laptop came with 1Gb RAM. Bought 2 x 2Gb matching SODIMM and installed iaw manual, on booting system failed POST and locked in the Toshiba 'welcome' screen; no access to BIOS. Removed one stick, system booted, BIOS recognises correctly, checked second stick, same result. I expect 3 - 3.5 Gb to be recognised by 32 bit OS but am confounded by the POST failure given that both modules are OK and the system works. Am I missing something or is it a serious problem? I'm still within warranty - just!
