[mic1996tam]

I tried to install a virutal network like vLan,USB WiFi or VPN, but the computer crashed after loading them.

Dervice:
Network Card: Atheros AR8151 PCI-E Gigabit Ethernet Controller (NDIS 6.20)
Graphics Card: AMD Radeon HD 6900M Series
CPU: Intel(R) Core(TM) i7-2820QM CPU @ 2.30GHz
Hard Disk: M17X_RAID0

Please help me!

That can be due to incompatibility with the motherboard or due to outdated drivers. What is your motherboard model and the operating system you are using. Find the right drivers and then only run the same. If it still crashes then provide the error number which is displayed on your screen. Is it a blue screen or the system just reboots directly without any indication.
