The computer stopped working suddenly; it had been fine the previous night.
Hello everyone, I'm going to describe my problem first: Last night I was watching a movie on my PC and everything was running as usual, turned off the computer and went to bed. The next day I push the power button and my monitor doesn't display anything, tried checking the HDMI connection and all seemed fine, tried a different cable and nothing changed. So I opened up my pc and noticed that all components seemed to work fine except for the CPU fans, they weren't spinning but were like trying to. I unplugged and replugged the fans on the motherboard, nothing happened; tried clearing the CMOS for good measure, nothing happened; tried booting the system with one stick of RAM; nothing happened. Tried booting with just HDMI cable and power cable; nothing happened. PSU fan seems to still spin when I push the power button so I'm at a loss here. Maybe my CPU just gave up? I have had this computer for a long time and I've been out of the tech loop for some time so I dont know what else can I do, help please. System specs: -CPU: AMD FX 8350 (no overclock) -GPU: MSI Nvidia GTX 1070 -RAM: 24GB 1600mhz i think DDR3 (2x8GB) (2x4GB) -PSU: Rosewill 550W bronze -Motherboard: Gigabyte 970A-UD3P -Storage: 2TB Adata SSD -CPU Cooler: Noctua NHD15 -OS: Windows 10 Home 64bit
It seems like a PSU or board issue. Inspect the board for damaged, swollen, or burnt capacitors. Look around the PSU for any signs of a burnt odor and examine it with a flashlight to spot any suspicious capacitors or parts. Edited March 3, 2023 by An0maly_76 Updated, more details
Inspect the fan blades and their condition. Look for any signs of damage or misalignment.
Last week my device almost stopped working. The night before I watched a movie called NOPE and everything seemed okay. The next day I turned it on and nothing happened. Zero results. Then I checked everything inside, confirmed all connections were correct, and still no start. While experimenting with the wiring, I removed some labeled wires and used a small screwdriver to try booting. It worked! After turning it off, I untangled and cleaned the cables, reassembling them. It turned out the issue was corroded pins. Fixed it all. You might face the same thing—just ensure everything is clean and give it another try with a screwdriver. Good luck!
Purchase a 3$ PCI debug card promoted as a PC analyzer. It provides postcodes that are highly helpful for troubleshooting and overclocking. For postcodes, note that 00 indicates failure—likely a CPU VRM issue. I suspect the 55 and 23 values correspond to RAM errors A9/A0/Ab, suggesting it's functioning correctly.
