Bought a few Fit3Pro's a while back, I now need to upgrade the RAMM to 4GB. (double it up)
I bought some Crucial 4GB DDR3-PC3 10600 SODIMM 1.35V 204Pin (part number CT51264BF1339) x 2
PC no longer boots up, I have 2 sets on RAM and two PC's and it happens on both units.
The PC front light illuminates when powered but that's it.
I thought RAMM upgrade was the easy part

Any thoughts would be great.
Thank in advance.
