Hello all! I have bought some new RAM for my Lenovo Computer. It supports up to 2GB of RAM, so i have bought 2GB. It origionally had 1GB. When i exchange the 2 512mb modules for the 2 1GB modules the computer will boot as normal but then crash/ freeze on the desktop! The make of the RAM is crucial, and the RAM before was crucial. (it was also recommended by crucial). I have gone into the BIOS looking for any Memory/RAM settings aswell as voltage settings but can't find anything! Does anyone have any idea why this could be happening? Any help would be greatly appreciated Josh.
