Hi everyone,

I’m facing an issue with my PC where it’s stuck in a boot loop. When I power it on, the lights all turn on, but the system stops for a second on the green LED light before restarting the cycle. It keeps repeating this, but the computer never shuts down fully. I get no display, and the boot loop continues, though occasionally it does boot up normally, and everything works fine once it does.

This issue started two days ago. Here’s what I’ve tried so far:

  • Resetting the CMOS.
  • Reseating the RAM (took them out and placed them back in).
The problem persists, and I’m not sure what else to try. Any suggestions or troubleshooting steps would be greatly appreciated!
 
When you do get it to start, let’s get all of your system specs.
No personal data is published and everything shown is safe.

1) Download Speccy by Piriform.
In Speccy, click File > Publish Snapshot > Copy to Clipboard > Close.
Paste that link into your post. Is Speccy safe?

2) Download GetSystemInfo by Kaspersky.
In GSI, click Start. (takes about 10mins)
It makes a ZIP file on your desktop, drag that to their GSI Parser site.
Once analysed, paste the newly created URL into your post.

3) Download MiniToolBox by Farbar.
In MTB, tick List Installed Programs, click Go then close the program.
A file MTB.txt is created in the same folder, attach that to your post.

4) No software interrogates the Power Supply Unit so list the make/model and age.
 
But I don’t think I will be able to get it to start it happens rarely and it takes to long.
 
Thanks for your reply! Here’s the information you asked for:

  • Motherboard: ASUS TUF Gaming B650-PLUS Wi-Fi
  • Graphics Card: AMD RX 6750 XT
CPU ryzen 5 7500f
 
Did you clear the cmos by removing the battery or did you short the pins.
Remove the power cord and press the on button a couple to discharge residual power.
Power cord back in and turn on whilst holding the DEL key.
Can you access the bios?
If yes does your drive show in the boot menu.
Are you using an M2 as the main boot?.

Also may we have the make model and wattage of your power supply.
 
I removed the battery and waited 5 min and it worked but the next day same issue again.

But now I can’t even enter bios and when I could I was using if my M2 as the main boot

The first day this happened It was boot looping but when I restarted it booted and I could play games but the next day same boot looping and since then my pc hasn’t booted.

I don’t know exactly my PSU I got it from my uncle but I know it’s a Corsair either 600 watt or 650 he said it’s pretty old maybe 7 years or more

It is important when asking for help to give an accurate description which you have done but it likewise just as important that you use the correct terminology as it helps to determine the difference between a hardware and a software issue.

A boot looping issue would suggest a software issue but what you describe is a computer that is failing the power on self test which is hardware and not Windows related.

The most likely suspect and quite possibly an issue with the power good signal between the MB and the PSU, a seven year old PSU that you do not even know the name of has quite possibly irreparably damaged the GPU and possibly other hardware.

Your build needs a minimum of a 650W or above Gold efficiency rated PSU from one of the following, Corsair RM range, EVGA, Seasonic or Super Flower, seven year warranty minimum but preferably ten.
 
Thank you for the feedback. To clarify, when I mentioned the boot looping issue, I meant that the system continuously restarts during the power-on self-test, with the green light flashing for about a second before it loops again. The computer doesn't shut off entirely but keeps restarting, and it does pass the initial POST checks, as all components seem to be recognized at first glance.

And my psu is Corsair and I’m pretty sure it is 600 watt but it has worked past 5 months and from nowhere this happens.

If it was a Hardware Fail it wouldnt be able to come to the green Boot Light correct me if im wrong

There are numerous things that can cause POST to fail and among them is the power good signal between the MB and PSU, you need to swap in an appropriate PSU or get the PC tested by a tech who has the required spec and quality of PSU, have a read

Using a PSU that you know zero about is akin to playing Russian Roulette.

Already advised in my reply #10 so you must have missed it;

I would not purchase anything until the system had be tested using an appropriate PSU, borrow one if you can or have a local tech test the PC if you can`t, ask what they will charge first though.

Couple of questions for you;

Have you tried a new CMOS battery.

How many drives so you have and what are the details of both of them.

Do you have a keyboard hooked up and what are the brand and model name or number of the keyboard.

You are welcome btw :)
 
Yeah the PSU was the issue. I had one 500 watt psu that I had from a pre built pc now I plugged in everything it boots perfectly fine.
 
Thanks for letting us know but while we are pleased to hear that the previous PSU has been confirmed as the culprit I strongly suggest that you act on the guidance from my reply #10.

Least expensive that I could find here this the absolute minimum spec that you need and must have.

If you want to future proof slightly more expensive is the 750We version here
