BSODs are driving me crazy

Hi,

I have a Lenovo z610 laptop, have been getting random and infrequent BSODs for a while now, which although annoying, I could just about deal with.

Recently however I have been getting them a lot more, some days it wont do it, others, like today, I will get them every 20 mins or so... I am running CAD software, but it reboots itself even if I have no programs running.

The error signature when I get back into windows is now constantly:
BCCode : 1000007f BCP1 : 0000000D BCP2 : 00000000 BCP3 : 00000000
BCP4 : 00000000 OSVer : 5_1_2600 SP : 2_0 Product : 256_1

I really dont know what I am doing, but I have put the minidumps into the debugger and get this (or something similar) out.

UNEXPECTED_KERNEL_MODE_TRAP_M (1000007f)
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: 0000000d, EXCEPTION_GP_FAULT

I have tried deleting and reinstalling the ati driver, as well as rolling it back... but the BSODs are still happening. I have got Lenovo System Update installed on the laptop, so I do have all of the latest/recommended drivers for this laptop

I would really appreciate it if someone could give me a hand as I have got no idea what to do!!!!

Thanks

Norton AntiVirus (all versions, but you have 2008) has usually been the biggest issue in these types of faults.

Members may ask you to try different drivers, and confirm all security updates are done, also run full Antivirus and Spyware scans.

But in my opinion it's Norton (again!)

Thanks kimsland...

Would you suggest I just get rid of Norton and put something else like AVG or Avast or something??? Or just try and turn off some of the features of Norton???
