trying to overclock cpu using bclk

[samstalker]

using bclk to overclock i3 2120 ,i overclocked to cpu from 3.3ghz to 3.46ghz i did a stress test for 10 min temps where good and everything was fine but when i started an online game i noticed that after 30sec everything was frozen and i'm moving alone (it used to happen when lagging but the ping was stable and the was no fps drop)then after a while i stopped and couldn't move i can barley turn using the mouse tried to connect to different connections restarted the game nothing worked,so could overclocking have affected the i/o port?
