You've experienced a situation where your PC powers on but fails to boot, despite the fan running. The back panel shows a faint white residue. You're cautious about handling it, wanting to examine it first.

If it's just a surface stain (no scratches), wiping it away should work. You can also use isopropyl alcohol for better results. Could you share your PC specifications?

Is there any visible oxidation? You're also noticing the CPU and RAM indicator lights on the board.

Ensure it's clean, then check if posting works again and proceed with troubleshooting.
