I looked at your six most recent dumps, all from today. These dumps indicate hardware problems. Two of the dumps are showing stop error code 101, two show error D1, and two show error code 1E.
STOP 0x0000001E: KMODE_EXCEPTION_NOT_HANDLED
Usual causes: Device driver, hardware, System service, compatibility, Remote control programs, memory, BIOS
STOP 0x000000D1: DRIVER_IRQL_NOT_LESS_OR_EQUAL
Usual causes: Device driver
STOP 0x00000101: CLOCK_WATCHDOG_TIMEOUT
Usual causes: Device driver, BIOS bug, hardware defect
Let's start with addressing the 101 error code. Please read the following threads and post back with any questions you have. http://www.sevenforums.com/crash-loc...oubleshtg.html
Follow usasma's advice in that first thread.
I found the following obsolete drivers on your system.
nvm62x64.sys Fri Oct 17 17:01:06 2008 (48F8FD12)
nvstor.sys Wed May 20 02:45:37 2009 (4A13A711)
Both of these are Nvidia chipset drivers. nvm62x64.sys is an Ethernet (network adapter) driver and nvstor.sys is a NVidia storage driver. I would also make sure you have the latest video drivers.
We need your system specs to help you with finding these drivers.
