My computer was working fine in the morning, I was playing a few games with no issues. I later shut down the computer and tried to install two case fans. I turned on the computer and it ran for 5 seconds and suddenly turned off, it wouldnt power back anymore. I tried changing the cables, switching power supply, reinstalling and shorting the front connectors, but nothing works. Please, someone help me no one has responded on any other site and I really dont want to just buy new parts.
