[go2guy]

now the mouse, monitor and keyboard won't respond???? I cleaned it out too and did not see where I disconnected it anywhere and the computer turns on when we hit the power switch. Does anyone know what's wrong with the computer? Recap: Installed/upgraded memory & air dusted inside now mouse, keyboard and monitor won't respond even though the computer can still power up??? Thanks

If the old memory was working put it back into the PC. If the computer boots with the old memory, then you might want to check if your motherboard is compatible with the new memory.
