Hello , first the specs :
cpu : Amd fx 6300
gpu : Zotac gtx 750 ti
ram : 8 gb patriot , and another one ( dual channel )
mobo : Asus - M5A78L-M
Ok , so i have gotten a new cpu cooler ( maelstorm 240t gaming ) and installed it on christmas day , after 2-3 days it started crashing , like my game just frezzed and there was a loud buzzing noise coming from the headset , i tried fixing it , and i did think i got it , after that i tried overclocking my cpu ( first with software to see if i have good result and than i started it in bios ) i did it in bios for 4.1 ghz and it just frezzed , i restarted it and it was running normal but , still at 3.5 ghz , after this my pc would just start doing random crashes ( no noise ) and sometimes not even starting * only the pc starts , not the keyboard , monitor or the mouse * , i said f**k it and got out my bios battery and restarted my bios , chill for like 4-5 days than it started again doing that , i said it's provably something wrong with my cooler , i put back my stock one , and now it started doing it again , i don't know what to do anymore , any help please ?
!!!!!!!!!! Btw , i installed on christmas another pair of ram , yesterday i put it back in pc and it did some crashes and after that my pc was doing again that only pc starting. (sorry for bad english if so) BTW I HAVEN'T WORKED WITH THE VOLTAGES IN BIOS.
