BSOD randomly happens every day, mainly error 0x0000003b

Hello,
These BSODs are happening daily, and I can't find the cause of it myself. I have tried the following:

1. CHKSDK /r (no errors)
2. memtest86 (no errors)
3. tried all kind of stress tests (CPU, GPU)
4. resetting all components of PC
5. reinstalled AMD Driver(installed disc version got BSOD, updated got BSOD, installed clean version from website got BSOD anyway...)
6. Updated chipset, audio, ethernet drivers
7. Checked for viruses with malwarebytes

I have MSE anti-virus, so I don't think it's the cause.
The last thing what I can do is to format HDD and reinstall OS but it's the least thing I want!
It would be really great if someone could see these logs.
Edit: Forgot to mention I installed OS in 2014-08-12 and started getting BSODs at least once a day starting with 2014-08-15. Maybe it's something related with MS updates.

Code:

BugCheck 3B, {c0000005, fffff80002e8ace5, fffff88008458630, 0}

Probably caused by : ntkrnlmp.exe ( nt!KeAcquireSpinLockRaiseToDpc+55 )

Hi bsod321.

Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 consecutive passes.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

If there is no error, enable Driver Verifier to monitor the drivers.
Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

   Information

Why Driver Verifier:
It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.

   Warning

Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there is no points, make a System Restore Point manually before enabling DV.

   Tip

• If you fail to get on the Desktop because of DV, Boot into Advanced Boot Options > Safe mode. Disable DV there. Now boot normally again, and try following the instruction of enabling DV again.
• If you cannot boot in Safe mode too, do a System Restore to a point you made earlier.

Let us know the results, with the subsequent crash dumps, if any.
