UNEXPECTED_KERNEL_MODE_TRAP (7f)
This means a trap occurred in kernel mode, and it's a trap of a kind
that the kernel isn't allowed to have/catch (bound trap) or that
is always instant death (double fault). The first number in the
bugcheck params is the number of the trap (8 = double fault, etc)
Consult an Intel x86 family manual to learn more about what these
traps are. Here is a *portion* of those codes:
If kv shows a taskGate
use .tss on the part before the colon, then kv.
Else if kv shows a trapframe
use .trap on that value
Else
.trap on the appropriate frame will show where the trap was taken
(on x86, this will be the ebp that goes with the procedure KiTrap)
Endif
kb will then show the corrected stack.
Arguments:
Arg1: 0000000000000008, EXCEPTION_DOUBLE_FAULT
Arg2: 0000000080050033

--------- update the network driver.
First, download the network card driver from manufactuer's website.
Then reinstall the driver:
- Click the Start Button, type "devmgmt.msc" (without quotation marks) in the Start Menu Search box and press Enter.
- Double click to expand "Network adaptors".
- Right click your network card and click Uninstall.
- Check "Delete driver software for this device" check box, click OK.
- Restart the computer
- If windows does not auto configure the appropriate drivers at startup, install the downloaded one manually.
Now a suggestion, out of experience. Decision is your.
►
Use Microsoft Security Essentials.
Uninstall Norton and all Symentec products using
Norton Removal tool. (At least as a test, as there is no proper ground of network drivers failing).
Use
Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and
free MBAM as the on demand scanner.
Download and install those, and then run full system scans with both of them, one by one.
Let us know the results.
