Posted January 18, 2022 Ok so this is my friends computer. It doesn't have any issues other than it sometimes just doesn't turn on. It's getting worse. Sometimes it doesn't turn on for hours (Motherboard rgb works tho even when nothing else turns on). He thought it was a PSU issue. He brought it to my place I tested it on my system and his. And at my place it worked well. On his system and mine. Like no issues at all. When he brought his computer over I saw his GPU was plugged in the 2nd slot of his motherboard, which I thought was the cause of the problems. I changed it to the 1st slot. But 3 days later. His computer sometimes doesn't turn on. Computer doesn't turn off when being used even under full load. System specs are R5 2600 B450 tuf gaming plus (no bios updates done since it was working perfectly fine before) Oloy 16gb 3000 cl16 1650 super Silicon Power SSD Corsair VS450 (bought in 2017, it's the version where "vs" is written in orange, not in white) Note: this power supply belonged to me. I used it for 3 years until January in 2020 (i3 6098p and rx 460, had no issues). When he bought it from me his graphics card (also my rx460) had a ferret that fried which rendered the graphics card useless. But after that no issues. The computer was running without any issues. For 2 years We also just did a fresh install of Windows like 3 weeks ago. Wiped everything, even all the programs. I dunno what the issue is. The motherboard looks like it's working well, everything works as it should in the bios. Can it still be the power supply?

Posted January 18, 2022 If the PSU was so bad it won't turn on then it would do the same in your machine. Let's rule that out for now but very likely a hardware issue. Have you tried a min config when this happens? Turn system off and remove power cable, make sure to try other power outlets on the off chance that is bad. Then remove one component at a time with power cord out until the system POSTs. If you only have one 16 GB stick of RAM then I would bring your RAM over to try too. Don't forget to try the fans last! I have had fans cause power faults I kid you not Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

I have had fans cause power faults I kid you not I think I found the issue, it may be the battery on the CMOS. Cuz my friend said that time is often wrong when the computer turns on. He doesn't have a multimeter so I'm gonna ask him to just buy a new battery cuz they are relatively inexpensive. If it doesn't work then I'll have to try other things, like the fans CPU r5 5600x Motherboard Arous b550 pro ac v1 RAM Tcreate 32gb ddr4 3600 cl18 GPU 1660 super Storage SN570 1tb PSU Corsair CX750 Audio Lots of chi-fi iems Operating System Windows 11 (lastest) Link to comment Share on other sites More sharing options...

If so TIL Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

I tried a barebones boot, even then it would not boot CPU r5 5600x Motherboard Arous b550 pro ac v1 RAM Tcreate 32gb ddr4 3600 cl18 GPU 1660 super Storage SN570 1tb PSU Corsair CX750 Audio Lots of chi-fi iems Operating System Windows 11 (lastest) Link to comment Share on other sites More sharing options...

My guess at this point is bad MB as the fries GPU could have affected it some. The only other thing left would be CPU. Have them try a different MB or RMA it Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
