Thanks for your help,Splatoid! I'll check RAM and I'll tell you how it went. The thing with my neighbor is that he told me that he hasn't had the blue screen again, so now he doesn't care as long as the PC won't crash...He's such an ignorant! Now,if it's a bad RAM stick...Why doesn't it happen every single time he boots the PC? Thank you,once again for your help!!!!
