PSU: EVGA 500W
I currently don't have a video card yet.

When I turn the PC on, it turns off in a minute or so, then it does like an on/off loop non-stop. Even when RAM is off.

Try disconnecting the hard drive (and any other drives), keyboard, and mouse. See if it comes on and stays on. Obviously, you won't be able to do anything. But it may tell us if it is a faulty peripheral device, or it's something internal to the board. I presume you didn't make any changes recently to any wiring or any settings in BIOS.
If the issue is still present, unplug the monitor cable next and try again. If still no joy, I'd have to agree with your conclusion about the board.

This is probably going to be confusing maybe, but when I tried the first time to power the PC without the hard drive, it turned off/on a few times, and then stays on for a while. But now, it is doing the same problem than earlier when I powered it again. But what I am concerned about is that the red LED on the motherboard is on the DRAM. That happened when I first powered it on without the hard drive. Does this mean something?
EDIT: Okay, when I plugged the hard drive in, the problem even became worse than ever. First I didn't even had the chance to turn it off, once I did it turns back on somehow. Second, it kept turning off/on even faster. I managed to turn it off, but the red LED light on the mobo is still there on the DRAM once it was turned on.

Found out that the RAM wasn't seated correctly, so I corrected it and the issue is still the same, but the red LED on the motherboard doesn't appear for RAM anymore. So I decided to test it once again without the hard drive connected, but the issue persists.
EDIT: I have an other question in mind. So if I have a motherboard that has 4 RAM slots but I only have one stick of RAM, what RAM slot should I choose?

4 RAM slots? The MSI H110M PRO-VD only has 2, and a single stick slot isn't specified in the manual. So it apparently doesn't matter.
Now, if this is a rhetorical question about a board with 4 slots, you need to first check the manual. Some require a certain slot be populated first. Others don't.
But back to your original problem; did you disconnect everything like I suggested above?

Kind of hard to be 100% certain from this far away. But if you (1) disconnected everything from the board as mentioned above, and (2) are sure the PSU is good... then yes. I would have to conclude the board is bad.
You might try leaving out the RAM and see what happens.

What do you mean by disconnecting everything from the motherboard? What do I need to disconnect specifically? Also, I replaced my PSU so it wouldn't likely be the PSU. I tested the PC w/o RAM on and still does the same issue.

By disconnect everything, I mean no drives, keyboard, mouse, gfx card, (monitor to iGPU). I'd leave a stick of RAM in since you said removing the memory didn't change anything. Unplug all the FP header wires and (using a screwdriver tip) start the system by momentarily shorting the two pins that the power button would connect to.
If no joy, you'll probably have to remove the board and ship it in. When you do that, check that nothing slid under the board that may have been shorting out the back of the board. You might even want to lay the board out on some insulated surface and test it again out of the case.
Hopefully the board is still under warranty.

Well when I tested the motherboard outside of the case, it still does the same issue. Case cables are disconnected, even the FP connectors. The only that is connected to the motherboard is the power supply. What is interesting however is when I took off the CPU power connector and turned it on, it stays on. So when I put the connector back and turned it one, the issue still persists. I even tested this with and without the hard drive and it is still the same. I seriously now suspect it is the motherboard, but I am not sure what you think.

Yeah, with no CPU power, there is no way to tell if that was normal operation w/o the CPU power or a clue. Is the board still under warranty? If so, you can send it in... and wait. Or buy a new board while you wait and end up with two. One you can resell.

one thing rule out a dead short in the case. pull the mb and put the ram stick in slot a0. see if it reboots. if it does outside the case try a test power supply. on your mb make sure the 24 pin and 8 pin eps power cables are plugged in.

It has no warranty with the motherboard, so I have to buy a new one. But which best motherboard should I get for my Intel Pentium G4560? Also, do damaged motherboards fry a CPU or RAM?

While it is indeed possible for a damaged board to kill components that are plugged into it, the chances are not high. I can't remember if you already mentioned this, but which PSU do you have? (don't feel like scrolling thru the whole post looking ;-)

I have a 500W EVGA power supply which is brand new. I am planning to buy a B250M PRO-VD motherboard because I heard that it is the good motherboard for the 7th gen processors

Okay, I will buy the motherboard next week. I will update you if I receive it. Thanks for your help!
