System stopped working two weeks ago - I'd hit the power button and it would try to start for 1/2 second then turn off for 3 seconds then try to start again and repeat until I pulled the plug. Got a new power supply and computer worked fine for 3 days then started doing same thing. I got another new power supply and nothing - same problem.

I changed the CMOS battery, cleaned the RAM contacts and reseated the sticks. No improvement.

Motherboard is a Maximus VII Hero running Win 10.
