Computer has been working fine for a year then recently it just turned off on me and turned back on for a second and off very quickly with fans and lights
on and then off later on I would keep it off a couple days I would turn it on and it would work then no usb or vga or dvi from graphics card or mobo worked so i bought a different mobo which was a ASRock H97 PRO4 ATX LGA1150 Motherboard and placed it in it made the usbs and vgas and dvis all work but the computer still wouldn't turn on so i also bought a new psu which is a CORSAIR CX-M series CX450 450W 80 PLUS BRONZE Haswell Ready ATX12V & EPS12V Modular Power Supply. The computer worked fine i even reinstalled windows and installed all softwares and what not couple days pass after i just bought the new psu and the computer turns off again and then 15-30 seconds turned back on. I have kept it off for the time being and then recently i turned it on after a couple days of being off and it was fine but eventually the same problem occurred. I just dont know what the problem could be any ideas? I appreciate it a lot thank you.
