BSOD - Every 30 min

I have uploaded the dump files.

The stop error seems to happen 30 min or so after start up. It does not happen with any specific program, and it started happening a week ago. Please help.

I have ran disk check. No errors
I have checked ram. No errors
I have updated Bios
I have updated video card driver
I have updated wireless adapter driver.

I need help immediately.
