Issue with PC failure after two years of inactivity, even when not in use.
Issue with PC failure after two years of inactivity, even when not in use.
I've been traveling recently over the past three years, and my dad mentioned he used the PC about two years ago to retrieve files. It worked properly until it shut down. When I came back home a few days ago, the motherboard's LED was lit but the case power button didn't respond, with no indication of power reaching any other parts. Also, I'm unsure what the POWER1 button does—could it be an alternative to the case power button? It didn't activate the PC either. I might have used it five years ago, but my IT or overclocking experience is fading. After unplugging all connections, cleaning the vents and filters with a microfibre cloth, and making sure everything was secure, the system still functioned as it did two years back. Since power appears to be going directly to the motherboard, I'm thinking a CMOS reset or a full rebuild might be necessary. Any suggestions? Thanks.
Without a full replacement could you still swap out the GPU and RAM, it's pretty simple. Reconnect all the power connections too. As mentioned before, install a new motherboard battery. Adjust everything to its default settings and run a test. If it works this way, enable XMP and verify the BIOS time and date. It might be helpful to try without the GTX 1080 Ti and use the built-in GPU first.
I disassembled and rebuilt it, replaced the CMOS battery, yet performance stayed the same. Also experimented with a single RAM stick, one SSD, without a GPU (using the built-in), and still no improvement without connecting a keyboard, mouse, or monitors, using a bareboard boot, tested PSU, everything seems okay there. Still notice the blue LED in the middle of the motherboard as before—it stays steady, not flashing—but the system won’t power on, which is really frustrating.

Thanks for the ideas. My dad brought it to a colleague in IT who noticed an issue with the power regulation on the motherboard. It turned out the PSU was fine, but the mistake led to a wrong diagnosis. After sharing the news, friends came together and built me a new PC, only adding my PSU and GPU. I’m planning to give the remaining parts of the Phanteks tower to my little cousin, who’s planning to build his first PC.
