Power flickering on and off, won't post.

[Blu3Jay]

Ryzen 3600

700w corsair non modular 

5600 msi gaming x and 

32gb 3600 corsair rgb (8x4)

Asus b450f strix 

 

This build is very new, less than 5 months old. None are used and I can almost be sure that all parts are functional. 

 

I noticed I was starting to getting some system instability so I decided to restart my pc, the only thing is that it didn't turn back on. When I tried to hit the case power button it just tried to start and then it flicks off, does this on repeat until you hit the power supply switch. 

 

Any intial thoughts or help would be fantastic, thank you.

Some interesting things of note, I got it to work again but I have no idea how. It decided to randomly post this one time I flicked the power switch on. Then I got some leds. They said it was ram, so I reseated my ram, and now it's working again???? Case closed or does anyone think it could have been something different. Also I didn't change or move my ram prior to pc failing

I'd double check all your front panel cable to make sure it's properly plugged in and not snagged on anything.
