These BSODs occur few times a week. I've taken the laptop to the lab, and they said that a they didn't find problems in memory or HD.

If it detects errors, replace the faulty RAM. If the memtest tells no error, please download CPU-Z [4], look in the memory and SPD tab and verify that the current RAM Speed and the Timings match to the values that you see in the SPD tab. If your RAM run at CR (Command Rate) 1T, change the value into 2T in the BIOS.
