installing 1.5gb ram
hi guys, when i bought my pc it had 512mb of ram, a few weeks ago i brought another 512 so now i have a gig. today i went and brought another 512 but when i slotted it in, my operating system wouldnt start,the pc starts but it says there was an error and asks me either to start in safe mode,last known good configuration or normally, no matter which i choose i just get a blank black screen. my motherboard is an msi amethyst-m and msi website says it supports 4gb,i have 3 sticks of ram, they are all 512mb pc3200 184pin. what do i need to do to get it to work with 1.5gb instead of 1gb?
