When I upgraded the power supply the computer booted up fine. Few hrs later, came back... shut down computer and reinstall new rams and now computer will not turn on. I took out reinstalled the old power supply and still will not turn on. I reinstalled old ram without new rams, still will not turn on. I checked for loss connector and still not working, no beeps, nothing... Motherboard and the power supply has steady green light (No blinking just still green) I own gt5014 and no fans turn on.
