first of all im sorry for my english. English is not my native language.
I have a problem with my PC. One day i was playing a game when PC shut down. Since then i can't turn my PC on. I thought it may be a PSU or MB so i bought new PSU first (no change) and then new MB but still no change. I tried different RAM and GPU, but nothing changed. So IMHO i think it "must" be the CPU. Few days before it crashed, PC was unable to boot up because of CPU overheating.
