I'm forced to change memory slots.

[anvesh mydg]

To clean the PC I removed my all the connections (and two of my monitors connected) and whenever i put back all the connections and start the PC the monitors won't turn on but they do as soon as i switch the memory slot this is the second time this has happened and I have two slots which won't work (Monitors are not getting the display). I would like to know the problem because i have a lot of work related stuff on my computer.

These are my following specs:
AMD Fx-8350 eight core processor
Nvidia GTX 960
MSI 970A-G45
8Gigs Corsair Vengeance

What model of DRAM and what slots work - count from CPU, so slot 1 is closet and goes out
