Hardware or software issue?

[2wiremodem]

Hi people,

I just bought a new mobo + cpu recently.

MSI Z97M-G43 + i5 4690K

I have already updated everything, drivers and all.

But i keep facing this error AppHangB1 while playing dota 2. It happens very often.

Is it my motherboard is faulty or it is just windows problem?

Need to pay to use the Refcurepro program. I have tried googling for all kinds of fix already.

I'm using my IGPU and the problem is not there anymore.. probably GPU problem..
