There seems to be a problem with my computer.
There seems to be a problem with my computer.
This situation could be quite challenging, so thank you to everyone who understands. The problem began about two to three months ago while I was using my PC regularly. It suddenly shut down, and even after restarting, nothing happened—though the RGB lights remained active. The next day it wouldn’t power on at all, so I suspected a failed power supply unit. I replaced the PSU with a new identical model and it worked. A day later, after regular use, it stopped again. I changed the power cables and connectors, but it still didn’t function. I brought it to a repair shop, who said everything was fine. That confused me further, so I returned it home, which now operated perfectly. Recently, when I turned on the PSU as usual and tried to boot, the PC failed once more. I examined the cables at the back, changed them, re-plugged the motherboard, swapped out one RAM stick, and even removed the GPU. After each attempt, it would either work or not. Today it happened again—trying all connections and still nothing. I reinserted everything, powered off the machine completely, and it finally started working smoothly. I’m really puzzled about what could be wrong and would appreciate any insights or suggestions. Please let me know if you have any thoughts.
Your PSU is from a specific brand and type. Windows will enter recovery mode if the system crashes repeatedly during boot.
Uncertain but looks like the problem might be with the CPU or motherboard. The 13th and 14th generation models often faced issues like overvoltage, oxidation, etc. If it wasn’t fixed promptly, performance could decline. Also, if the old PSU was defective—sometimes warranties cover replacements due to inconclusive testing—it could be an outlet fault. I’m more inclined toward the CPU or motherboard concerns.
The most affordable and practical option would be to ask a friend who can provide a compatible part. Otherwise, I’m considering purchasing from the used market to get the cheapest or extremely affordable CPU that fits your motherboard, ensuring it doesn’t have this problem before testing it.
Yes, consider upgrading the motherboard and CPU if you're facing any problems.
It varies depending on your goals. If you plan to upgrade, consider removing the parts you don’t need. Temporarily use your PC without the 4090 to see if the issue persists—this suggests the component is fine. Similarly, test storage options in different slots to find a working one. If you decide to upgrade, replacing the faulty RAM is usually the best choice. Before making changes, try various configurations to identify the problematic part.
I'm sure you're doing well, just like I thought. If you can't try it yourself, I'd recommend taking the PC to a repair shop. But based on what you shared: the place you found doesn't look very trustworthy. If you have other choices, check local reviews or ask for shops that actually perform thorough tests and even inspect parts individually.
