Hi, I am having a sony vaio VGN-FW51MF which had windows 7 home. I made a clean install of windows 7 professional but I am facing BSOD problems. I try to update the yk62x64.sys file (Miniport Driver for Marvell Yukon Ethernet Controller., Marvell) from the Marvell website, the bsod stopped but the computer freezes in random times, so I roll back to the old driver. Can you help me with debbuging ? I attach the dump files and cpu-z screens! Thanks!
