Okay. I have had my setup for a long time now and recently after shutting it down for the night... It would never boot again.

I have reseated everything...the PSU is brand new... So is the ram. And I bought a new motherboard (same exact one) and still nothing. LED light stays on...no longer post beep codes.
I've also have had the RAM seated in the area (blue slot) as instructed by the manual. I utilized the MEMOK button and have cleared CMOS too many times.

I wonder...can the CPU be the cause of the issue if it went bad?

I have
Motherboard: ASUS M5A99x EVO R2.0
CPU: AMD FX 8350
RAM: 8 GB (new) DDR3
PSU: 650w Thermaltake

Well, here's what I'd suggest. Get a cheap FX CPU, and for God's sake stay away from the 9xxx series models, that's a whole other story, and try it. Fortunately, while AM3+ motherboards are getting pretty scarce, the CPUs are easily obtained. Even new.

You can get a used 8350 for anywhere from 20 to 50 bucks on Ebay and they are still available new for not too much more than that. Thing is though, to me, it's probably not worth the investment when you can get into a lower end Ryzen configuration that slaughters the 8 core FX cpus for around 300 bucks. But that's 300 bucks that might not be possible to somebody just trying to get their current system working so I understand either way.

Good luck to you in any case.

Absolutely. The memory controller is in the CPU, so no CPU, no memory function.

Pull the CPU and make sure you didn't bend any pins.

Did you have this problem before you replaced the power supply? What MODEL of Thermaltake PSU did you buy? Smart series? TR2? Both are not very good. If you have your old PSU you might want to try that after checking the CPU pins, however, since you say this problem started prior to replacing the motherboard, PSU and memory it doesn't fit.

Try stripping it down, no drives attached, disconnect the connections from the power button on the front of the case and jump the two pins to attempt starting up. Try only a single stick of RAM. And just for grins, if you have another graphics card, you might try swapping that out as well. GPU card can affect other circuits on the PCI bus sometimes. Make sure the CPU fan is coming on, sometimes a failed fan will cause false error codes.

It could just be a dead CPU, but that is a very rare situation unless something else failed and killed it or it was abused somehow. CPUs normally don't just die without being damaged physically by a drop, bent pins, overclocking thermal fatigue, lack of cooling, direct motherboard short, something.

To be clear... I'm speaking of the D_RAM LED indicator staying on.
The PSU is the SMART 650w. I only have one RAM stick. So yeah. However, I doubt this is the issue because I recalled having an issue where the CPU had an issue initializing period and took 2 RAM sticks with it. But, I got it to boot. issues was, I had 12 GB installed...windows stated that only 5.87 GB was usable. Plus the CPU gets extremely hot, extremely fast, but I read AMD FX CPUs are notorious for that.

Now that I think about it, this Device had been urinated on by cats at a friend's house. I took alcohol to the board and all the components and it worked fine, like two years, until recently baring the CPU issue (a few months ago). I'm assuming something got messed up due to corrosion, though I thought I cleaned it. But, that was the old motherboard. This new one is doing the Dram Led too.

So, THIS current issue began about two years after you replaced the cat piss motherboard?

It was running fine on the new motherboard for 2 years, and then just out of the blue, with no hardware changes, no moving hardware around, cleaning the inside of the case or anything at all, just quit working overnight while it was shut off?

All hardware that is currently installed is the same hardware that was installed when the problem began, or is this stick of memory, PSU and motherboard new SINCE the problem began, but did not correct the issue?

No it started on the old board and carried over to the new one. There were no real dramatic changes to hardware. The failures with RAM and CPU started on the old Mobo after two years. I replaced the power supply 4 months ago..so yeah. It has to be the CPU.
