I built this PC a little over a year ago, and it's been fine. I don't use it much, mostly stick to my laptop. But a couple weeks back, it wouldn't POST. After messing around with it – unplugging stuff, holding the power button – I found that if I hold the power button and flip the power supply switch on and off, it boots up. Then it runs fine for hours.
The next day, or shortly after, it wouldn't POST. I gave up and used my laptop. But then, after a 5-10 minute delay, it booted normally, having only pressed the power button. Later that day I updated BIOS and turned off computer didn't use it over weekend.
Monday morning, my computer failed to POST when I needed it for work. I tried waiting for it to boot, but after a frustrating 25 minutes, it remained unresponsive. Attempting my previous workaround—holding the power button while toggling the power supply switch—also failed. Further troubleshooting involved clearing the CMOS and testing RAM modules individually in slots A2 and B2, all to no avail.
Recently, a new issue arose: the computer would take an excessive amount of time to POST, and when it did, it would get stuck with a yellow LED on the motherboard. I resolved the yellow LED issue by downgrading the BIOS and enabling 'Memory Context Restore' in the BIOS settings. Initially, this appeared to fix the problem, as I was able to shut down and restart the computer without issue, and it even booted normally the following day. (YAY ISSUE IS FIXED) and I was wrong it didn't.
However, after leaving the computer untouched for 2-3 days, it once again failed to POST. I tried unplugging it from the wall and leaving it disconnected overnight, but this did not resolve the issue. The computer now only POSTs after either holding the power button while toggling the power supply switch or by pressing the power button and waiting for an extended period, which can range from minutes to hours. Another thing, If the computer is running I can immediately power it off and back on using the power button without issue. However, if it's left off for several hours or a day, it won't POST unless I use my unusual workaround
Here's the weird part: once I actually get this thing to boot, it's rock solid. I work from home two days a week, and I'll use it for hours with zero problems. No crashes, no heat issues, no reboots, no random shutdowns nothing. I'm actually using it right now, CPU's at 42°C, GPU's at 41°C, running great. It's just getting it to turn on that's a issue.
