I could really use some help or advice. I built my own PC two years ago, and it's been running smoothly for the most part. However, the AIO cooler LEDs never worked from the start. So, after two years, I decided to give my PC a deep clean since it had accumulated a lot of dust, and I also wanted to try fixing the cooler LEDs.
I ended up partially rebuilding my PC, taking everything out except the fans and cooler. I spent a few hours cleaning each part with an air compressor and then fully rebuilt the PC, feeling 95% confident there wouldn't be any issues.
Unfortunately, when I tried to turn my PC back on, it didn't boot. I decided to leave it for the night and try again the next day (today).
Here's the issue: when I turn my PC on, everything seems to start working—fans, etc.—as usual. But after the usual 30 seconds it takes to boot, nothing happens. The PC stays on, but there's no signal to my monitor. My motherboard displays the error code 97, which the manual says means "Console Output devices connect." I have no idea what this means, so any help would be greatly appreciated!
