Stop 0x0000007E help

My computer just recently started to give me a blue screen sayin ****Stop : 0x0000007E (0xc0000005, 0xf9007264, 0xF96B4638, 0xF96B4334)?

I get errors like this

Service Control Manager

Error None

7001 N/A

DESKTOP

The IPSEC Services service depends on the IPSEC driver service which failed to start because of the following error:
A device attached to the system is not functioning.

Also The TCP/IP NetBIOS Helper service depends on the AFD service which failed to start because of the following error:
A device attached to the system is not functioning.

Errors like that are the most common ones.

LOTS of possibilities:
