Question HELP figuring out what is wrong with my PC

[julleess]

Hello, Five years ago I built my first PC, with the following components:
-Ryzen 5 2600
-MSI ARMOR RX580 8G OC
-16GB RAM 2400Mhz
-PSU Corsair CX650
-1TB HDD
-MoBo ASRock B450M Steel Legend

My PC never had any troubles until a week ago, my PC would start but say it has no Signal Found, and then getting into a restart loop.
Everything like the fans, the gpu fans, the CPU cooler starts.

I don't know what's wrong, tried restarting through the restart button on the case, tried disassemble and reassemble,
changing cables, and nothing still. I have a video of it because I feel I don't explain quite well.

How old is said PSU? It's on the low end of quality, to begin with, so it's a likely candidate.

My PSU is 5 years old, but as I mentioned in the post everything on my PC starts, but the signal doesn't show at all.

A failing PSU can cause a restart loop. Being meh quality to begin with, and now out of warranty, it is why I say it is likely.

That said, I just had my work PC do a reboot loop. We determined it was motherboard or CPU, after trying everything else. Without having spare parts to test out, it's something that can be difficult to diagnose. We had an identical working PC, that we were able to use to test things. If you have access to another PSU or GPU, it would be a good place to start.

Oh I see, Unfortunately I do not have access to another GPU or PSU.
Any Idea of something else I could try?

You could try using only 1 stick of ram at a time. After that, if that does not work, you could try disconnecting your drives, to see if it can at least get into bios.

When in doubt with zero options. Take the whole thing apart and put it back together.

Could just be a loose cable somewhere.

I've also had a bad SATA power cable cause a boot loop. As soon as the USB controllers turned on it would restart, so you would see the Windows load start and immediately fail. Could use the BIOS and everything. That one took a while to track down.

If the PSU is suspect STOP.

IF the PSU is failing, the GPU may not be getting enough power to start up and is the direct cause of the signal loss. By repeatedly attempting to restart you could be under-volting the entire system which WILL DAMAGE OTHER COMPONENTS EVENTUALLY, if not already. Find a good, quality PSU and resume testing. Unfortunately this is one occasion where "Replace with known good" is the recommended diagnostic starting point. Only proceed with what you are doing now if you are willing to accept the risk of further loss.

Furthermore, a PSU replacement will rule out the most critical component which is fortunately, also the cheaper of the two likely candidates (GPU being the other). And based on the age, probably something that should be replaced anyways. PC's require maintenance, PSU replacement is part of that, once a certain age is reached.

 

[julleess]

What PSU would you recommend?

 

[julleess]

As I mentioned I did take the whole thing apart and it it back together, still kept having the same issue of not displaying signal and then the whole loop boot

did you try other monitor cables on the gpu? like hdmi, displayport, or dvi...

 

[julleess]

Yes I did.

Power supply is probably the first place to start as those do age and as they get older can’t always output the amount of power they once did. The CX series was their mid range/ semi budget line as well. So that’s probably where to start.
