I left my PC powered off for a week, and now it's not booting up. I replaced the CMOS battery beforehand since I suspected it might die soon, but that didn't fix the issue. Interestingly, my speakers are still getting power since their RGB lights are on. I've checked for any visible damage, but aside from some dust, everything seems fine. Here's what I've already tried: replacing the CMOS battery, holding the power button to drain any residual power, and leaving the case open to let out any humidity. I'm not very experienced with this kind of thing, so I'd appreciate any help with troubleshooting steps I can take.

You should check your components one by one. If you have any spare parts, swap them in to test. Start by unplugging everything except the basics: just power and the monitor. If you have integrated graphics, that might help, too. Try removing the GPU and see if it boots then. If it does, add components back one by one to pinpoint the issue.
Have you noticed if the fans spin or any lights when you try to power it on? That can help diagnose the issue. If nothing happens at all, it might be a bigger problem.
Unfortunately, no—nothing seems to happen at all.
I don’t have any spare parts, but I did unplug all the external devices like keyboard and mouse, and it still didn’t work.
