Vista Crashes (Blue Screens) with an error message mentioning yk60x86.sys.
We’ve got a bunch of Sony Vaio VGN-SZ5MN laptops at work and a lot of them are blue screening (BSOD) as soon as you plug in the Ethernet cable. If that’s not enough of a clue (hehe), the problem is the Marvell Yukon Ethernet Controller driver.
To fix the problem, download the updated driver from the Marvell Driver page.
Or try this direct link to the Driver Installer for Windows 2000/XP/Vista
