[SOLVED] Desktop Keeps Powering on and off

[jekuma21]

Okay, I'm currently upgrading/rebuilding my tower. Putting everything in a new case, upgrading the RAM and CPU, and adding a video card.

These are what I got:
GTX 1050
2 2400mZ Hyper X 8GB ram
Intel i5 7500K Processor
Seagate 3TB Hybrid Drive

Having experienced previous issues before (and learning from them), I only used what was absolutely necessary to boot the computer (the ram, cpu, and hard drive). However, within 5 seconds, the machine shut down and quickly powered on again (it didn't even reach the bios screen). It did this repeatedly until I shut it off myself manually. I looked up why this could be happening and I heard it was power supply related. However the power supply I'm using was working perfectly before I put everything in the new tower (this could still very much be the issue though). I have also heard it could be RAM or CPU related, however after an hour of switching between the old parts and the new parts, nothing changed. Also the motherboard seems to fine, as it does turn on when I press the power button.

So yeah, I'm running out of ideas. Its either the PSU or the motherboard.

What motherboard using? Make sure that the RAM is properly inserted in the slot.

 

[jekuma21]

My motherboard is the B250M-DS3H

 

[alexoiu]

If starting the board without RAMs installed, still same restarts? Can you connect an internal speaker to the board and check for beeps?

 

[jekuma21]

It still restarts, even though it did take longer for it to restart (about a few seconds longer)

 

[alexoiu]

Try inserting now single RAM module and test. Make sure that you are fully inserting it in the slot. Some require more force. However, take care to not break something.

Now when I did it RAM-less, the motherboard powers off in about a second. Same with a single RAM module.

Try taking a picture of the board, uploading it on imgur and posting the link here.

Always test with CPU cooler installed.
CPU high temperatures can cause those restarts.

 

[jekuma21]

I just did, its not booting to the bios screen.

 

[alexoiu]

Then not sure what could be wrong. A local pc store might help.

Is there a chance that it could simply be PSU related?

 

[alexoiu]

Hard to say, without testing with known working parts.

Just now, I checked to see if there could be any bent pins on the socket but I instead came across small white things (maybe dust?) on the pins of the socket. https://imgur.com/a/tlNDCkh

Could these things be the issue, and if so how could I remove them?

 

[alexoiu]

They could be. Try using a magnifying glass, some isopropyl alcohol and cotton swabs, or something even thinner.

Not to disagree with alexoiu but I'd not use cotton swabs. If one grabs the pin it could bend it. Super easy to do. I'd say use compressed air at a distance. I also concur with the diagnosis. I had a bent pin destroy my overclocking ability. You look to have several covered.

Okay, turns out it was a problem with the motherboard. I just got a replacement and when I booted it up, it doesn't power cycle. However it did power off once (with no rebooting) since I forgot to connect a fan. But other than that its fine.

However, now my monitor isn't recognizing the signal; even after changing RAM and CPU. Could I be missing something?
