OS: Windows 7
Motherboard: H61M-DS2
GPU: EVGA Nvidia GeForce GTX 660
CPU: Intel i3-2105
RAM: (2x4) Kingston HyperX DDR3 1600MHz
PSU: Corsair CX600

^ That build has been working flawlessly for about a year or more. I have to use my laptop now because I tried to fit an Intel i5-4460 into the Motherboard which, I had no knowledge of at the time, was an LGA1150 socket trying to fit into an LGA1155 socket. When I booted the system up the CPU fan was quite loud for a short time and then the system went into the problem I am having now; The system keeps trying to boot but fails, so it tries again and again. Fans are running, LEDs are on but not a single Post Beep anywhere. (This happened with the Intel i5 and is still happening even though I switched back to my Intel i3)

What is troubling me most is that I did some Breadboarding and still could not get the system to boot. All I had in the Motherboard was the PSU and the switches to turn on the computer that were from the tower case.
I have tried adding my Intel i3, cleaning, checking for fried circuits, adding 1 and 2 sticks of RAM, and resetting the CMOS (Idk, I think I did? I don't have a Jumper so I used a screwdriver and the screwdriver did not work to boot the PC up without having to connect the power cords from the tower case)

I'd go for it being some kind of short you caused when using the wrong cpu given the circumstances when the error began, as the socket number refers to the number of pins then the contacts would have lined up incorrectly when installing although I could not say for sure if this would cause permanent damage.

did your computer reach bios post?
if yes, then try to reset your motherboard cmos..

and try to build your system out of your computer case..
if your computer running flawlessly outside your case, then this is because of motherboard shortage.

if it's not, then try to replace your psu.
you can borrow from your friend etc..
usually it's because of faulty power supply.
shorted capacitor or bulged caps in secondary side of psu can cause this symptom..


cx series usually fail after 2-3 years due to low quality capacitor, but it can happen even after a year of usage

I looked inside the PSU. Everything looked fine. No blown or bulged capacitors but I did find something on the main large PSU cord: One of the metal insulations for a pin is missing. The pins that usually look like [::] where :: is the metal inside. This single pin looks like [ ] inside. Could this cause the problem?

Update: Oops, never mind. Saw that no wire exists for that pin. I did do a paperclip test on my PSU and the thing ran fine. (Seemed a little weak but I don't remember how loud it was to begin with)

I am starting to think it's the CMOS and that I didn't reset it correctly. If my PSU was running with the paperclip and I tried my system with just the PSU + CPU hooked in, even with only the PSU hooked in, is it safe to assume that the issue here is the Motherboard?

well, afaik, wrong processor will not damage your motherboard. it's just simply refuse to boot.
at least i did something like yours in the past..:D
But idk, there's always bad luck out there..

okay..
Try to build your system outside your computer case..
and make sure this time you really-really reset your motherboard CMOS..

if you are unsure if cmos has reset, it will do no harm to remove the battery for half an hour and then replace, this will guarantee it is reset.

Also aren't there different number of pins between 1150 and 1155? Is it not possible using the wrong cpu would cause a short across some of the pins and possibly kill the board?

Battery was taken out for well over an hour. I have tried several other methods of resetting the CMOS and several ways of doing those methods so I am pretty sure I reset the CMOS, however, no results. Still the same problem.

Is this a Motherboard issue? I am really leaning toward this because all these problems happened after I force-fitted the CPU which has a different socket. As I have tested earlier, my PSU was running with the Paperclip test. (This is all being done by breadboarding. I have never put in the GPU since there's no reason to; the problem persists without it. Even without the CPU.)

Ok. This problem isn't a very big setback since I was going to buy a new Motherboard anyway. Once I get the Motherboard in and have tested it (and if it works) I will say the problem was a fried motherboard component. Solution: Buy a new motherboard.
