Computer freezing, BSOD, no particular reason

Hi!

I'm getting this problem. I turn computer on and it either immedately freezes, and I have to restart it with the power nutton or it's giving me BSOD and restarts. After multiple restarts it usually starts working and it works for few days without turning off, no problem. I had a graphic card that was refurbished, and i thought this is the issue so I recently replaced it with geforce 560. Well I still have this problem. I'm starting to think this is issue with either my mother board or maybe hard drive? Or maybe even CPU? How can I check? What should I do?

Im using ASUS with the phenom x2 3.3 ghz (6cores) 12 gb ram, geforce 560

Oh I should add that it happens particularly often if I have two monitors connected. Sometimes even the bios message doesnt show up when i start computer it just turns on and stays dark. Currently I disconnected second screen, since I trned on computer without second screen it froze once and I got BSOD twice.

I think everything should be fine with connectors but I'll check again. I managed to get the contents of the dump file. Maybe somebody will know what to do with that?

IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: fffff880c3088281, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000000, bitfield :
bit 0 : value 0 = read operation, 1 = write operation
bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: fffff80002e9e4e6, address which referenced memory

Thing is I'm getting this for a while now. No more then two days ago i replaced the graphic card and I was forced to reinstall the windows, so I have a new clean installation of Windows 7 with barely anything on the hard drive. And still the same issue

Boot up in safe mode and see if your problem remains.

Ok so it seems my RAM was faulty or at least two different brands were incompatible. after removing 2x2gb of Ram that came with system originally and leaving only 2x4gb I purchased separetely everything seems to be fine. I'm using system for few days now and not even single BSOD.

Thanks for the help everybody!
