Looks like your networking drivers to me. One of the dump files blames rt64Win7.sys, while the others blame networking in general.
Please:
- download the latest version of the networking driver from the RealTek website: Realtek
- uninstall the networking drivers/program currently installed on your system
- install the freshly downloaded drivers and monitor for further BSOD's
Please upload the memory dump file dated 02/10/10 - this error code is different from the others - a STOP 0x127 (more info here: BSOD Index )
Most likely this is a driver issue - but it can also be malware or a defective networking card.
Also, please update this driver. Although it doesn't appear in all the memory dumps, it's old enough to cause issues on it's own: lirsgt.sys Sun Jan 29 06:13:28 2006 It's a component of the Tages Copy Protection software and you'll find a link to the update page under the drive name here: Driver Reference
