I think I Might Have Russian Trojan Fysbis on my computer

[stop0x0000000a]

I live in Russia and despite being not a fun of Yandex I really doubt  they infects their users with any kind of trojans.

if they would do that they simply lost the market.

I would suspect overheating, motherboard capacitors, power supply or something similar, i.e. start with memory test for instance.
It is always possible to reinstall the OS if the hardware is ok.
