Hello, I was hoping someone could help me out. To start off, I used that phenomenal mega-thread pertaining to power issues that I found in other threads. Unfortunately it was unable to help me. Please forgive me for my wall of text but the past 48 hrs have been hell for me with this issue. Please help me!

Here is my build and my problem will follow:
Monitor - Acer XFA240 bmjdpr 24"
CPU Cooler - DEEPCOOL GAMMAXX GT BK, CPU Air Cooler
PSU - Corsair CX Series 650 Watt 80 Plus Bronze
RAM - Corsair Vengeance LPX 16GB (2x8GB)
MOBO - ASUS TUF B450-Plus Gaming Motherboard
CPU - AMD Ryzen 5 2600
GPU - Zotac GeForce 1060 6gb

Problem: One day my 144hz Monitor would was not receiving a signal, which was odd because I had used it the night before with no issues. But that’s when the issues started. Thereafter my PC would either 1. Boot the first time and stay on, 2. Boot the first time, but then shut down, but then boot the second time, 3. Boot the first time, turn off, boot the second time but only for a millisecond and then shut down completely, or 4. Not power up at all. These occurrences are extremely inconsistent and I cannot see a pattern. Then I referenced the “power issues” mega thread and started working. First, I unplugged and re-plugged every power cable, but it wouldn’t power up at all. Then I resocketted all of my hardware. GPU, RAM, made sure they were in tight, took them out and put them back in, rearranged the RAM in every configuration possible, would not boot. Replaced my PSU with an old one that I knew worked and would not boot. Took out my CPU and cleaned it, pins all fine, put the CPU back in, cooler on top, plugged everything in and it booted! Problem solved! I slept and it ran all night (and still runs) with no problem. I shut off the PC while I was away and came back and it would not boot. Ugh. For a while I was required to unplug the PC and plug it back in to reboot! I moved some wires around after shutting it off manually, tried to turn it on, it would boot but then immediately shut down. For a little bit it would only boot on a second attempt even though all I did was move wires. I removed my fan controller thinking that was the issue, and that didn’t help. I thought maybe it was my new monitor, I tried booting it with HDMI, still booted on second attempt, not first. Booted it without the GPU and it wouldn’t boot at all. Unplugged the MOBO power supply and plugged it back in, no boot. Unplugged the GPU PCI-e cord and plugged it back in with a new PCI-e cord and it booted the first time. Weird!!! And that’s where I’m at. It’s running and I’m afraid to turn it off because i can’t find the answer. Only thing I didn’t change is my MOBO, could that be it? I need help. Thank you

then after 2 start it goes up and boot the other test you might do is to check front panel power button if it is not getting stick in the case simply unplug it from board and gently touch the 2 pins to start system and if stay on give a look at case power switch some air can blow sometimes help .


Thank you for responding. I will do that when I get home. I have never heard of a PSU stress test, what results should I look for? and my PC works fine under load, its only turning it on, will stressing the PSU indicate what is happening upon boot?
 


Thank you, I will do the test tonight and post the results.
 


Here are the results. It recorded at idle for 1 minute and then ran for 5 minutes and idled for 5 minutes. Says no Errors.

Also, I just shut off my PC, I pressed the on button and it turned on but immediately shorted and shut off. I pressed the button again and it turned on and it’s fine. This is the new normal for my PC.
