My old gaming PC, I built it myself, but it didn't last more than 6 months. . . however, all I had to do was replace parts... and then I regularly maintained it about 2-3 times per month.... again, the thing broke cause it started to sound like a jet engine.. fans blowing at an insane pace. Then the Motherboard fried. I had a friend diagnose what really happened, he stated that it was something to do with the power supply. I guess there was not enough voltage? (Something like that) anyway, I had to donate it all to him cause he said he would repair it... that project has been in the works since 2011... haha
