Solved Is my motherboard dead or is it something else?

Specs: Windows Vista 64, Intel Core 2 Duo E8500

I recently upgraded an old PC and it was working great. This morning I was using it and then it went into sleep mode. I've never had a problem, but then it wouldn't come out of sleep mode when prompted (by pressing a key or moving the mouse). I then shut off the power, then turned the computer back on. Instead of POST, I get nothing except fans running. No beeping or display. It was odd.

So, I googled the problem and tried a number of things. I reseated the internal connections and reseated the RAM. Still the same result: just fans spinning and no beeping. I then tested each stick of RAM in each slot and still nothing. I even tested my old RAM, which was working at the time of the upgrade. I then tried booting with only the CPU/PSU/Mobo connected. No beeping or anything (even with all the RAM removed). I then connected my old PSU with the same configuration (just CPU/PSU/Mobo and no RAM) and that didn't help either. I then reconnected all the hardware to my old PSU and still, the computer would only "turn on" with fans, but no beeping or POST or display. I should mention that LED lights on the motherboard would still light up when turning the PSU back on.

So, I'm inclined to believe that my motherboard has finally met its maker. Of course, it could be that both of my PSU's have a bad rail?? What are the chances of that? Here are my system specs:

Intel Core 2 Duo E8500
500GB Crucial SSD
ASUS GeForce GTX 750 Ti
8 GB Crucial Ballistix DDR 800 RAM (4x2GB configuration)
EVGA 650W P2 Supernova
Windows 10

If the motherboard is dead, so be it, but I am just trying to make sure I didn't miss anything. Appreciate any advice or ideas and many thanks for your time in responding!

Change of the CMOS battery?

Removed the GTX750?

Remains the CPU or MB....

Yeah I took out the video card and tested it. Didn't think about changing the CMOS battery at all. Would that prevent POST?

Wow, a P5Q-E. I had the DDR3 version of that motherboard (P5Q3) as my first rig I built myself.
That is one old motherboard, 2008-ish, I wouldnt be surprised if its dead.
I've gotten life into even older motherboards, (Socket A, SiS 735 chipset, forgot the motherboard name), with Athlon XP 1600+ and 2000+ processors... But the only reason I've manage to breath life into that rig was because I had plenty of spare parts to toy around with.
Basically, test all parts if you havent already done so (going by your post you have). If it still wont go into post, the motherboard is probably dead.

Cue bagpipes, salutes and cannon fire in the background.

All, thanks for the responses, especially Johnw. The guides you provided were very thorough and since I had already went through the trouble of taking it apart and testing it, I thought why not just see if it could be some of these other things. I checked for blown capacitors and did another visual inspection. Nothing seemed out of sorts. I then decided to reset the CMOS jumper (taking out the battery was next). I followed the instructions in the motherboard's manual, reset it, turned the power back on, and got a bunch of beeps! I reinstalled the RAM, hardware, reconfigured the BIOS (which took only a couple of minutes) and was up and running in no time. Lesson learned here is to try simple things first before taking everything apart. I could've saved myself a lot of time. Funny thing is that when the computer booted back into Windows, all of my programs were still running like they were when the computer went to sleep. This problem is solved and this old board isn't done yet!

Thanks again for your responses.
