A lot of the crash reports are OOM (out of memory) reports where not enough contiguous free memory is available. Something is using up a lot of space in the Windows page file. With size of the Page File being 34 GB there is definitely something wrong there. There is still plenty of free physical memory with a System Memory Use Percentage of around 50%.

What does the Windows Task Manager show about the memory usage ?

Says I'm using 3.8/8.0 GB (49%) .

This is with only Firefox running, an open Media player and Task Manager.

This is not about physical memory, but about virtual memory stored in the OS page file that runs out of space. Your page file already seems to be quite large and still can't hold more data.

Thanks for the tips. It's not a Firefox problem as it is a pagefile.sys problem is what you're saying? So, if I've got 8GB of ram and currently paging file size for all drives is 20480 MB what should/can I increase it to to get best performance? If you wouldn't mind, and thank you.

Wow, was it configured by OS or by an user? Pagefile can't be bigger than your RAM, optimal should be 2-4 gigs.
