So basically I just got a new toshiba laptop with 4gb of ram. I had a 2gb ram from my old laptop which i added to the empty slot. However, the laptop did not boot or even turn on ..just a light on the powerbutton .. I think the two sticks were incompatible somehow due to different clock speed, voltage could be anything . maybe i touched the ram with static idk. Also, when i removed the 2gb ram, the laptop turned on fine with the ram it came with (4gb). now i am worried should i return the laptop? have i caused any damage to the motherboard ? or anything would up over time now? or just a memory failure?
