The PC isn't starting after more than ten hours without power, and it seems difficult to activate it multiple times.
The PC isn't starting after more than ten hours without power, and it seems difficult to activate it multiple times.
Hello, I'm experiencing a problem with our two computers at home.
The first one is an AMD Ryzen 5 2600 with 32GB of Crucial Ballistix RAM (16x2), paired with an Asus Tuf Gaming b450 Elite II Mobo and a GeForce RTX 3060 Ti with 8GB of RAM, powered by a Gigabyte 80+ Gold 750W PSU and a Forza power regulator rated at 2200V.
The second is an AMD Ryzen 5 1600 with 32GB of Delta T-Force RAM (16x2), connected to an ASUS ROG Strix B450-F Gaming II Mobo, a GeForce RTX 3060 with 12GB of RAM, and a Cooler Master 80+ Gold 850W PSU, also using a Forza power regulator rated at 2200V.
The issue began several months ago after a power disruption in our neighborhood that caused all lights to flicker for about two hours while we were away. When the PC came back online after over ten hours, it wouldn't turn on again. I connected it to another PSU, but the problem persisted. Eventually, I replaced the motherboard and CPU with that one, and after checking everything, discovered that the old CPU, a Ryzen 5 3600, was the culprit. It would fail to power on when in use, but worked once it was replaced.
Recently, about two weeks ago, my PC (the first one mentioned) started having similar issues. After a while off, it would turn on but fail to boot. The MOBO Lights showed a VGA fault, though sometimes it worked without the RAM or other components. Eventually, after several attempts, it booted and the lights cycled through CPU, RAM, VGA, and boot sequences. Still, I can't determine the exact cause since both PCs are connected to different power sources and have separate regulators.
Interestingly, my PC (the second one) began showing the same problem roughly two weeks ago. Its GPU has RGB lighting, making it easier to notice than the other's. When mine doesn't turn on, the PC won't boot either. After some adjustments, it works better. I've tried turning off the power supply switches behind the CPU and waiting 10 seconds before turning it back on, but it still doesn't work.
I'm puzzled because we have replaced the motherboards and CPUs, yet the issue remains unresolved.
Our PCs are connected to different outlets and have different power supplies. Our building doesn't experience power shortages, nor do we have any issues with electricity.
Note: The two GPUs were previously used for cryptocurrency mining by my brother-in-law, but he donated them after quitting. They've been in use for less than a year, and neither GPU shows any visible damage. Performance is normal, and they're functioning well.
Any suggestions? Thank you in advance for your help.
Have you experimented with testing a single RAM stick at a time for each motherboard? This helps identify if the issue lies with a specific RAM stick or if the RAM is faulty overall. Also, do you have access to another GPU that you can use in each PC for comparison?
Hello and thanks. I currently don't have a spare GPU available, although I believe I might be able to locate one later. Concerning RAM modules, I've tested all of them—first without any, then with one, then with the other, using dual-channel 2, then reverting back. It seems the success rate increases when I disable the power supply behind the case, wait about 30 seconds, and then restart the PC. This method works around 7 out of 10 times. However, it could suggest that either one of the parts was damaged or that the power supply itself is failing, which doesn't really make much sense to me.
I also want to note that when the problem began with PC #2 (my girlfriend's), she had a brand new GPU—AMD RADEON SAPPHIRE RX 580 PULSE 8GB. The issue involved the PC not turning on, and I’d like to add that during those times, the system would sometimes power on by itself after 1 to 3 hours from the last attempt. For instance, if you try to turn it on now, it won’t, but it will suddenly start within 1 to 3 hours. That was an old problem before we replaced the CPU and motherboard. Now her PC is much different—she swapped out the CPU, GPU, and motherboard over time, and the only persistent issue is booting. Do you think the power supply might be related? I don’t feel it does, but who knows... having both PCs have problems is kind of strange.
It might be the PSU's, especially your girlfriends, due to the power issue her computer faced. I wanted to ask if you could consider another GPU since yours were used for mining. I suggest avoiding them until you buy new PSUs.
