Error stop 0x00000101 and BSOD appears all the time

My computer started to show me BSOD time to time. I can work the whole day without any problem and three times in a row show me BSOD and error code stop 0x00000101. Please advice what could be the problem, I have reinstalled windows already 2 times, first time from Windows 8 to Windows 7, but it did not help. The worst part is that you never know when it can happen.
