The computer fails to start after it worked before.
Hello, Your built machine from about four to five months ago suddenly stopped functioning. Last night you used it, then put it to sleep overnight, and this morning it refused to start up. Here are the details: CPU – AMD Ryzen 5 3600 3.6 GHz 6-core; GPU – Asus GeForce RTX 3070 Ti 8 GB TUF GAMING OC; Power supply – Corsair RM (2019) 750 W, 80+ Gold certified; Storage – Samsung 970 Evo Plus 2 TB M.2-2280 NVMe + Samsung SSD 860 EVO 2TB; RAM – G.Skill Ripjaws V 32 GB (2 x 16 GB), DDR4-3200 CL16. I tried everything: turning it off and on, booting without peripherals, reseating components, cleaning CMOS by removing the battery for ten minutes, and double-checking all connections. Despite these efforts, the machine still wouldn’t power on. No one visited, and everything seemed fine yesterday. Any suggestions or assistance would be greatly appreciated. I’m really struggling right now.
IC Chips may sometimes become unresponsive. Remove all batteries, HDs, RAM, and USB devices, then let it sit undisturbed for 24 hours. Did the issue begin after an update? You might need to reinstall the operating system. Some poorly constructed OSes degrade over time with regular use. Try starting the device without any connected peripherals. Check all USB devices on another computer, and test the RAM and storage in a different setup. Place the HD in a bag, freeze it briefly, then run tests. Use a plastic or wooden tool to tap the motherboard while the unit is running, especially near potential glitch spots. Apply a thin layer of freeze spray to the transistor parts, looking for any signs of burn. Inspect for open diodes and check for any scorch marks on the board. Verify the power supply output voltages. In short, the problem could stem from a deeper cause—consider giving your computer some space and time before considering a replacement. You might also explore alternatives like Linux Mint for gaming.
My latest assembly has been behaving oddly lately. I checked the case, pressed the GPU, RAM, and cable connectors to confirm they were correctly placed, and that’s all. So far, nothing worse. I believe the expansion and contraction from higher temperatures during operation and then cooling for a while is leading to instability.
Thanks for the suggestion. I've also attempted to start without using the GPU, but it didn't help. It seems like my CPU might be failing, though I'm not sure. My processor is still new, so I'm not certain yet.
You're hoping to locate a working CPU for testing, though you suspect it may be nonfunctional.
You've tried connecting your little brother's CPU and it's not booting yet. The debug light suggests the issue might be with the motherboard itself. If the board were dead, would the fans, GPU, and lights still power up? It sounds like a frustrating situation—maybe it's best to take it to a repair shop.
Motherboard or power supply unit first, confirm the CPU 4+4 connection is correct. A possible issue lies in the motherboard’s data path to the processor—this could explain the symptoms if the board isn’t fully functional. The printed circuit board contains capacitors, resistors, chips, and traces; any malfunction there might disrupt power delivery to the CPU socket, causing a partial shutdown that triggers a warning light. While most components work, some may fail without full voltage or data flow. Alternatively, the PSU itself could be faulty. To verify, disconnect all components and inspect the PSU’s ATX connector (see instructions) for proper voltage output. Ensure you use a reliable voltage tester and connect the ground wire correctly, as grounds are separate from the board’s. This guidance was updated on June 8, 2022 by An0maly_76.
