Random BSODs (0x1E mostly, driver related?)

Hello!

I have not been here for a quite time. Now computer problems have started to occur randomly. I have:

ran memtest 86+ for 15 passes last night
prime95 for three hours
sfc /scannow
chkdsk
driver verifier with all non microsoft drivers for few hours now..

..And all clear. My bet is some driver or I have loose cables or something like that in my pc. These bsod's have happened very randomly, usually when browsing internet. It even crashed and didn't come up until cleared cmos.. And few times had freeze in post/bios.. Very random behavior.

Specs

8gb RAM 1333 kingston
Phenom 965BE Stock
6970
Win 7-64
1TB Samsung

Five BSOD's from 2015 attached. Thank you if someone could give me any help!

BTW, havent you noticed the attention on the top of the page before posting?

The crash dumps are pointing to anything and everything. In that case the first notion is goes to the hardware, which is somehow supported here ....

Code:

Probably caused by : hardware ( ____fffff88000dd1000+8126 )

Can you uninstall Catalyst 14.12 Omega and install an older version of teh display driver for a testing purpose?
