I bought a dell laptop about 3 months ago with 2GB of Ram. Since it was cheaper to buy memory from kingston than Dell I bought 2 more GB of RAM from them and installed it shortly after. Before I installed the ram everything seemed to work fine on the laptop. After I put the new memory in about 2 weeks later the integrated fingerprint reader (biometric scanner) went out on the motherboard and I had to send the system in for a replacement under warranty. Won't go into that story, let's just say a month later the laptop is finally fixed and working again.
By the way, only the area of the motherboard that uses the fingerprint reader went out, everything else worked just fine (I could still boot the computer and use everything but the fingerprint reader).
Now I'm debating if I should put the new memory I bought back in the laptop or could that have been the cause of the motherboard going bad for the fingerprint reader if the memory was bad? I'm doubtful that is the case, but just wanted to get some other input.
