ntldr or notskrnl missing when installing another memmory

[eatmars]

i just bought another memory because i have only one memory and its only 256

now my problem everytime i install the second memory the boot is always corrupted "NTLDR" is corrupted or missing but when i remove the new memory from the motherboard it works again

i already tested the new memory card by its own and its working perfectly with both slots but when i try to install them both theres the error again!

i know it something to do with cache or boot but i need more help from some experts before i make an experiment and destroy my computer completely

what mobo do you have and what memory do you have? Mixing and matching memory can cause problems.

its also happening to my sdram slot when i use two sdram their not working but when i unistall one memory it works.

the two memory works when i disabled the L1 cache and L2 cache but my computer became slow in loading when i disabled the cache
