BSOD - IRQL Not less or equal

Hi there,

I am getting this BSOD quite often (several times a day).

My system specs are
- Windows 7 x64 ?
- Is the original installed OS on the system
- an OEM orversion (Installed in a Toshiba Satellite R630)

- What is the age of system (hardware)? 1.5 - 2 years
- What is the age of OS installation (have you re-installed the OS?) I re-installed the OS a couple of days ago.

Any help would be very much appreciated... I have reviewed the dirvers and seem to be up-to-date... I thought the problem was due to Thunderbird, then to Openoffice, my external keyboard (HP 2.4GHz Wireless Multi-media Keyboard and Mouse driver) but could not find the solution.

Thanks in advance

Virtually all blamed on tcpip..sys and the usual true cause is either a malware app or firewall. I would remove McAffee and replace with Microsoft Security essentials
