I have an FX 8350 paired with an ASUS Sabertooth 990FX with a BIOS version 2104. I press the power when trying to boot my PC for the first time and all the fans spin up including the heatsink fan. I have reseated the CPU and checked for bent pins and I could not find any. I'm out of ideas. I had used the 8350 for about a week at stock before my old motherboard messed up and now 4 months later I am still swapping out parts trying to solve this thing... I am tired of dealing with it. Please help. Thanks!
Red CPU light??

If all looks good, see if you can swap out the psu, any that you know works, just unseat your gpus if its a small one. Only reason I suggest this, you have an RM 750, and they can have probs, crappy capacitors. I'd also breadboard your mobo, hook up absolute minimums, then 1 component at a time.

Motherboards very rarely 'just mess up', there is always an underlying reason. Considering your psu is an RM 750, I'd be inclined to start there as the culprit. They are built with the industries worst capacitors. One small capacitor failure can possibly lead to the psu frying everything hooked to it... Which is everything.
Get a different psu, borrow one from a friend, swipe one from an old pc in the attic. Breadboard the mobo. 1 stick of RAM, CPU cooler, system speaker , on button. And that's it. See if it posts. If it does, then the problem lies in one of the components you didn't hook up. If it doesn't post, use the other stick of RAM instead. If it still won't post, you have either a bad psu or bad mobo. If you use an alternate psu then you have a bad mobo. It everything hooks up fine, the original psu is bad.
