Why RAM is not supporting by my Dell optiplex pc?
I have Dell optiplex 990 with 4 GB of RAM. I bought more 4 GB to increase the RAM capacity. I bought same DDR3 RAM but after plugging in system won't start. With my old RAM its working but not working with new RAM. Just moving the fan and stops.
Shopkeeper has rechecked the new one RAM and that is working fine on other PC. What should i do?
