when I boot up my computer today, my computer would not boot up… it booted, but there was no display output or usb power. when I put a little research into it, I figured out that my computer was booting into POST and then stopping for some reason and then booting into it all over again. I thought my power supply was faulty at first, however checking it with the multimeter proves that it is working properly.
when I turn on my computer, the CPU fan will start very quickly, and then over the next few seconds it will start for a few seconds and then stop for a few seconds, signifying I guess it was going into POST, however post detected something wrong and then halted and kept restarting over and over again. looking at the error LEDs on my motherboard shows that my VRAM, CPU, and VGA are all having errors (blinking very quickly every couple seconds) which seems highly unlikely because I’ve use this PC in the past 24 hours, and it worked perfectly. not to mention it seems like the ram error light has always been on, while the pc was working properly.
everything in my PC is plugged into a surge protector, and I’m pretty sure I didn’t sleep through a thunderstorm last night, so i honestly don’t know what is up with it. is the motherboard right? have accidentally seated all of these components improperly? is the motherboard faulty? it’s brand new, built just a few weeks ago, and i’ve never experienced anything like this.
hopefully someone can help me.
here’s my specs:
Asus Prime Z370-A motherboard
MSI NVIDIA GTX 970 graphics card
Intel i5 8600K CPU
16gb (2x8gb) Corsair Vengence LPX DDR4 RAM

thanks in advance.

Something is obviously not working right, the problem is what. Start by simplifying. Unplug the power supply and remove everything from the motherboard except 1 RAM stick, CPU, and CPU cooler. Plug it back in and see if it will POST. If so, great! Unplug, add 1 thing, replug and test. Rinse and repeat. At some point it will stop posting (unless it was something that was poorly seated) and what you just added is probably the problem.

If it won't POST with just CPU, CPU cooler, and 1 RAM stick, try a different RAM stick. Still a problem, then it is probably the PSU, MB, or CPU (in that order).

Do you have a case speaker? If not, I would get one. It will help you diagnose the problem.

Try reseating the RAM. Remove the RAM sticks one at a time, clean the contacts, then firmly install the stick (make sure that the lever on the slot goes all of the way up), then repeat for the remaining RAM. Then reboot.

If that doesn't fix the issue, then try one stick of RAM at a time(as above).

Here are a couple of checklists on this topic.

so when i followed anotherdrew’s answer, unplugging everything except for the bare minimum, i discovered both of my ram worked, however when i went to check if my CPU was seated properly, i found some bent pins. plugging in the case speaker did nothing. picture attached.
by the way, my case is a Corsair Carbide Spec-06, and i plugged in the HD Audio connector. Maybe I plugged in the wrong one?

is you have an option to get it on warranty or to somewhere where they will fix this pins, better do so.
Also, the case speaker IS wrongly put. It should be on SPK or SPEAKER pins - in most cases it's right next to pins for power, reset, hdd leds etc. Other option is that this two pins (but spacing for 4) are sitting in one big chunk of pins - also described.
Anyway - case speaker must be put in ground (black pin) and +5V (red pin).

I've personally tried tailor's pin, but I've got few single ones spreaded throughout the socket.
I've also heard about buying smallest or second smallest (in diameter) needle in drugstore, then cutting it to be flat. They've used it as the way to insert the pin inside the flat end of the needle, and then gently put it back into it's proper position. This require more precision in movements but I think it pays off when it comes to time, cause you need less moves to proper position pin.
However, my recent experience with intel's socket 1150 failed (it did not fixed the problem, but I'm not sure if that was it) to succeed, so use it as last grasp. And definitelly NOT try to fix it, when you at least have option to send it back to manufacturer/store to replace it.

MERGED QUESTION
Question from negzersqu : "I'm out of options..."







Sorry, lol, i shouldn’t have used words like “died” when i described the symptoms of my PC. It turns on, but the problems are as listed above. It boots into post, doesnt go past it. The power supply has been tested before and works as it should.
Also, i have unplugged the card and tested with onboard graphics and it still doesn’t work.

Hey, if you are getting into post and NOT past it, you should be able to see, what is wrong. Protip is disabling fullscreen logo to be able to see, what's wrong. Besides, maybe the disks aren't working propertly or aren't connected propertly?
