POSTing problem, I might have found the solution but need to affirm it.

Alright, I've been here before. The last time I tried posting about my POSTing problems on these forums, I received a lot of information about my problem, but in the end I could not fix it. I have come back with some new information I might be able to use to help finally fix it.

So I am going to give a list of things I've tried and the things I've done before the computer refused to POST.

About 2 months ago, I finally got a monitor so I can use my 2 year old PC I built. The monitor worked well without any problems, but I had to switch out the RAM slots and only use 4GB of RAM. The computer POSTed fine after that.

Well, 2 days later I accidentally pressed the sleep button on my keyboard. The computer shut off and when I tried to turn it back on, it didn't POST.

The LEDs would refuse to turn on and the power button would be unresponsive after hitting it.

Also, the LEDs used to flash whenever the PSU was plugged in, but after replacing the PSU this stopped.

The GPU fan wouldn't move when not POSTing, either. This is the main reason I replaced the PSU.

These are the steps I took to try and fix this:

Switch RAM sticks and switch RAM slots.
Changing the HDD LED/LED and power button prongs (The LEDs were in a wrong configuration and usually the case LEDs would turn on to indicate a post)
Taking out the Case inputs (Audio, USB, etc.)
Pulling out the SATA cords.
Changing the CLR CMOS jumper multiple times and exchanging batteries.
Taking out the GPU and trying to use motherboard input
Fully deconstructing and reconstructing the entire PC
Checking CPU and Mobo for static damage/burns
Checking CPU for any lint, dust, metal pieces, etc.
Using a "makeshift" test bench.
Using different HDDs
and using two different PSUs.

After trying all of these steps, I was truly confused on how this problem could spontaneously happen.

Then, after thinking awhile, I thought back on how my RAM affected the POSTing situation. I believe both RAM sticks have failed and it might be what's stopping me from getting the computer finally POST. The computer going to sleep and never waking up must have simply been coincidental.

Also, the GPU might've failed, but that's such a huge piece of hardware (and a huge piece of my wallet, too) that I think that requires much more deliberation.

Also, the Mobo might've failed, causing both RAM slots and the PCI slot to fail, or it might just be the RAM.

Could I get a little help here on what might be causing the computer not to POST?

Also computer specs:
ECS Kam1-I
2x Crucial 4GB RAM
Athlon 5300 2.05Ghz
R7 250X 4GB
Seagate 250GB HDD
WD 500GB HDD (I found this from an old emachines computer and I was running out of space)
Black Rosewill case (I forgot the model number)



 
Solution
I don't know. From the information you posted, I would lean towards no. If you had access to the event viewer in windows, that might give me some ideas. But at this point it is more of saving what is left.



Normally on a otherwise working PC clearing the CMOS resets the BIOS to the default setting. That returns the system to a normal boot up. But that isn't the case here.

The minimum components needed to boot are a motherboard, CPU, RAM, PSU, and a monitor (plus a graphics card is integrated graphics isn't supported). The video linked below shows a per-assembly test of the components for a new build.

But that is essentially the same thing as breadboarding a motherboard. That is what I suggest. It removes as many other variables to narrow down the problem.

I do believe that the memory is a problem. Did you check to see that the processor and memory were compatible with your motherboard?

This is the website for your motherboard.

Here is the list of supported Memory.

Here is the list of supported CPU.

Yes, I have checked that the RAM is compatible. It is 1600 as specified and it has been working for 2 years since. I'll go ahead and breadboard once again. I also meant 5350 instead of 5300.

Thank you anyways.

Alright. I have checked the processor and I noticed the thermal paste is beyond dated. When I was breadboarding I noticed the computer wouldn't POST at all even with it barebones with one stick of RAM in DIMM2. I think it might be possible that the processor has burned out over those two nights. I don't know the symptoms of a burned out processor, but the heat signatures from CPU Z were a little higher than normal before the computer stopped posting. I'm starting to think it's less of a memory problem and more of a CPU problem. IF it is a CPU problem, the CPU is cheaper than a new stick of 4GB RAM.
 


Given that the motherboard is only about $30. I would start there. I would also get a case speaker.

Alrighty, is there still a way I can fix the computer without replacing parts? Maybe I screwed up the CMOS in a way that I can repair it again? I've tried clearing the CMOS using the battery and the jumper method, both to no avail. Is there still a way to fix the motherboard BIOS/CMOS without buying another one?
