Uggghhhh...memory Issue!

I have a VGNSZ645P3 Vaio which I got as xmas gift. I decided to Max out the RAM and purchased Crucial 4GB kit. Sony recommends Crucial as only authorized after market RAM. I have previously upgraded memory on desktops and laptops and am fully aware about the ESD. I changed the memory 45 degree angle, snap it down....I try turning the computer back on and it will not turn on. Power light is on, the battery light is on but the other 3 lights will not light up and screen does not turn on. I put the original back on and it still will not turn on. I took it to sony store and the guy tries same thing I do and it does not work. He says the motherboard is probably toasted...I said how could it be I followed every direction possible and he said sometimes that the Memory has ESD on it. So they put the original factory RAM back in and shipped it out to San Diego. I thought that warranty was void if you mess with original RAM? Im hoping they'll fix whatever that is wrong with it and not come back with "you messed with RAM warranty is void".....

Has this memory issue happened to anyone?

 

ESD can be tricky. Did you ground yourself before touching the RAM, and again against the computer's ground before inserting it?

 

I touched what I thought was a "metal" rail that the memory clicks into
