I have been messing with this for a while and I need to enlist some help. I bought this laptop off of craigslist and it came with a 1 slot 4gb of RAM. I wanted to add an additional 4gb of RAM. I looked into manuals and looked at everything I could before I made my purchase. I purchased exactly what they tell you to, but when I install the new RAM, and power on the laptop, I am given a blank screen, no BIOS, no beeps, Nothing. Even the GPU fan stops spinning, but everything else seems to be on. I tried updating BIOS, but Dell only offers the ancient ones on their site and I don't know where else to get my BIOS from. Please help me! I have tried just about everything and I don't know what to do. I have also gone into BIOS and looked for memory configuration, but it seems to be pretty locked down. Any suggestions please!
