You posted in the correct place.
You have several different errors but the one to concentrate on at the moment is the 0x50 because this can be caused by buggy antivirus software.
In this particular dump the Symantec/Norton driver BHDrvx86.sys was cited as the cause of your crashes. In fact it prevented another Symantec driver, symevent.sys, from being able to load.
We have dealt with
many people here who have had issues with Symantec. Either update your software or uninstall and try different security offerings. Because Symantec/Norton is notorious for leaving drivers behind even after you uninstall, the company had to make a removal tool to make sure all remnants were removed.
If you do decide to uninstall make sure you use the removal tool for your particular version.
The other two errors of interest are both 0XEA: THREAD_STUCK_IN_DEVICE_DRIVER
A device driver problem has caused the system to pause indefinitely (hang). Typically, this is caused by a display driver waiting for the video hardware to enter an idle state. This might indicate a hardware problem with the video adapter, or a faulty video driver.
Both dumps specifically cited the Nividia display driver nv4_disp.dll as the cause of your crashes.
* I would first deal with Symantec and take it from there.
