The computer is operating with the chassis fans active, yet other components are not functioning.
My hardware setup includes an AMD AM4 Ryzen 5 5600 CPU (Socket-AM4, 6-core, 12-thread, 3.5/4.2Ghz, 65w, 35MB cache) paired with a Cooler Master Hyper 212 Halo CPU cooler. The motherboard is an ASUS TUF GAMING B550-PRO. I have Kingston FURY Beast DDR4 RAM (3200MHz, 16GB, 2x8GB, CL18) installed. For the graphics card, I use an MSI Radeon RX 6650 XT MECH 2X OC. The power supply is a Corsair RM650x 650W unit, and there are four 11-inch chassis fans.
This system was recently upgraded two months ago, with all components except the PSU and GPU being new. About a week ago, the computer stopped working after several hours of use; the chassis fans were still running, but the monitor light remained on. Both CPU and GPU fans failed to operate, and there was no RGB lighting from the Cooler Master cooler.
People suggested removing the RAM stick and testing it, which resolved the issue—once I replaced one 8GB stick, the system powered up with the RGB lights coming on. The problem reappeared recently during a game session in WoW, where the screen went blank despite chassis fans continuing to run. I had to disconnect the power supply by flipping the switch, as the case’s power button didn’t respond.
Trying to relocate the RAM sticks or changing slots didn’t help either. Anyone have suggestions on what to try next or what might be causing this issue?
You'll need to perform a CMOS reset. You can look up instructions online, and it should also be outlined in your motherboard's manual (available online). Re-seat your graphics card as well.
Did you ever solve it? I suspect it was the PSU. That was the only thing that stayed the same. I’m facing the same problem. Just because some power is passing through doesn’t mean there’s a defect. You can buy affordable PSU testers. I recently had my PC keep restarting when I tried to break the loop and shut it down hard. It never turned on properly again—it would spin the fans but nothing else worked. Then I tried my wife’s computer, which worked until about a day later when it started showing display problems. The screen would just go gray with vertical lines. We tested various HDMI/DVI cables and even different power outlets. I also swapped out GPUs without any change. I believe the TV or the power outlet might have had a grounding issue that partially damaged the PSU... I’ll let you know what happened.
