Here's my rig:
CPU: AMD FX-8350 Vishera
Mobo: M5A97 R2.0
RAM: some GSkill DDR3 2x4GB sticks
Video Card: AMD Radoen r9 200 series 2GB vram
OS: MS windows 10 pro 64 bit
HD: booting off of my Seagate, forget specs but its a 1TB drive and has shown no signs of dying anytime recent (checked event logs and did a few diagnostics)

So my issue is my computer sometimes fails to post. I power on my PC and fans and mobo will be on (mobo light is green) but my USB and video wont get power. Then I will have to turn it off and on numerous times until it gets to the Asus mobo splash screen. I don't believe it's CPU as I reseated it and reapplied thermal paste. Could potentially be the battery but im posting from said computer right now so it would be very funky for it to only shit out on startup, like I could play a videogame for hours and be OK. My bet is its on the mobo maybe a broken path or something. I'm about to try a bios update but wanted to see if any of yall had some useful input. Also don't believe its a loose cable thing either, I took apart the entire computer but problem still persists. Post if you need more information.
