Hello, as stated in the title, the fans of my pc start when I turn on the PSU and when I hit PWR they rev up for half a second and stop over and over again. I might add that when I last turned off my pc it was frozen. I hard reset it and went to bed. I come today, 2 days later and it won’t start. I saw a very similar thread on here but nothing works. I tried using a different PSU for CPU and Motherboard connectors without success. Please help. I need it asap for a school project.
