I have a Dell Inspiron 3800. I purchased the system off-lease and opted to have an extra 128mb of RAM installed. When I received the computer it said I only had 128mb. I contacted the company and they sent me more RAM. When I went to install, I found that they had installed RAM (I probably should have checked that first, I just assumed they would have done it correctly). After searching google to find why the memory wasnt showing up, I updated the BIOS to see if that would allow the system to recognize the new memory. It did for the first reboot (everything but diagdx said 256mb). When I rebooted again it said there is new memory, press f1 to continue or f2 for setup. I pressed f1 but it kept coming up every time I rebooted so I figured there was something I had to change in the setup. I went to the setup screen in f2 BIOS and listed at the top was time and date settings with the ram and what not below. I could change time and date but could not access any values for RAM. After I exited this screen and went on, the memory was no longer recognized and it went back to 128mb. How do I get my system to accept the new memory again? I'm sure I did something majorly wrong. Thank you so much for your help!
