Given 's report that the PC was muddy and components were pulled and rinsed, and noting earlier replies from and , the immediate priorities are safety, contamination control, and protecting any important data. Avoid powering the system until all visible grit and chemical residues are removed and the parts are fully clean and dry.

Practical cleanup workflow (for boards, cards and connectors):

  • Work on a non-conductive surface, wear gloves, and photograph + label connectors before further handling.
  • Remove loose dried grit first with a soft anti-static brush so silt isn’t smeared.
  • For mineral/oily residue left after rinsing, use high-purity isopropyl alcohol (90%+). Apply with a dropper or brush and gently work debris free; alcohol helps displace water and evaporates quickly.
  • Use low-pressure compressed air in short bursts to clear channels after alcohol treatment.
  • Final drying in a ventilated, warm spot with desiccant packs (silica gel) is safer than direct high heat or heat guns.

Parts to treat with extra caution:

  • Power supplies exposed to floodwater should be replaced rather than reused because they pose safety/fire risks after contamination.
  • Storage drives: if the data is critical, stop DIY attempts and use a professional recovery service. Repeated spin-ups risk making mechanical damage permanent.
  • Cheap items (optical drives, some fans) are often cheaper to replace than to fully restore.

Reassembly/testing:

  • Only after thorough cleaning and several days of drying, bench-test the motherboard outside the case with minimal components and a known-good PSU. Be ready to power off immediately if there’s burning smell, smoke, or abnormal behavior. Keep realistic cost-vs-repair expectations — after flood contamination, replacement is often the most reliable option.

Well fitstly let it dry (for at least a week in a warm place) then assess the damage. Its likely to be a total loss due to water damage (if it gets into the caps on the motherboard it swells them), but the HDD is probably salvagable.

the bigger problem is that the computer is covered with mud. and, when I opened it it has mud all over the inside part. Please tell me where to start. I mean, what parts could've probably been damaged or what parts can be used. We just cleaned it, after we've pulled every parts out. We rinsed it with water and try to wipe every mud as much as possible

Use of a hair dryer has been known to help, but I do not fancy your chances of salvaging much.
