Something doesn't seem right from just this.
Most pins and connectors on computer parts are made with corrosion resistant material. Either the thing is made with said material, or it's plated. Now mechanical wear can rub off plating and create issues, but you'd have to be doing a lot of insertion cycles.
In addition, I lived in a humid subtropical island with the ocean literally a 5 minute walk away. I rarely used the AC so I had plenty of ocean air coming in. The computers I've used were fine for years, with the only thing showing corrosion were the case, and even then, only a thin surface layer.

high humidity especially near a ocean area can cause that. What type of case are you using ?

The anti rust finish on less expensive cases might leave a lot to be desired.
I remember Cadmium passivation tanks at work for plating steel metalwork. Nasty stuff. I think it's been banned now.
A Lian Li Aluminium case wouldn't rust, but still might corrode.

hello! hope you are well,
As you said in your thread SSD and HDD connecting points are getting corrosion or rust so if you want to address corrosion on your PC's components you just need to Reduce humidity, fix leaks, improve ventilation., Use silica gel packs, Apply protective coating, Clean regularly, Seek professional help if needed.
If you're prepared to strip all the components out of the case, you could paint on anti-rust compound as used by vehicle repair shops.
You leave the compound on for an hour to do it's job, then wash it off. If the rust is bad, use a wire brush or sandpaper before applying the compound.
Allow the case to dry thoroughly after washing, then spray with clear varnish or a paint colour of your choice

Ventilation not reducing humidity, I don't know why. I use silica get pack. The problem is it's rusting only on connecting point, I can not put silica directly on connecting point of ram or ssd, I put them in case but not helping. I already went to professional but they said to reduce humidity. But again the case or my another dual core pc ram or ssd not corroding. So I don't know what is this all about this pc?

probly not actual gold.
gold doesnt actually rust most likely copper connectors.
there isnt really much you can do to prevent it apart from regulate temperature.
only way to prevent it completely ( not recomended is replace all components and make a old school mineral oil pc. rust needs oxygen if its submerged in mineral oil it cant rust. that is a massive pain though.
however if your intrigued i could link ya to some old videos.
Help! That's the worst case of corrosion I've seen for a long time.
When you used the term "rust" I thought your problem was with steel chassis parts. To be strictly accurate, the term rust only applies to iron and steel objects and is Iron Oxide.
Gold does not rust and unlike Iron, it does not combine readily with Oxygen in the atmosphere.
The gold plating on DIMM contacts and CPU pins is a very thin layer a few microns thick. Gold is a very good conductor of electricity and is used on electronic components to reduce the contact resistance.
What I think is happening in your PC is the metal underneath the gold plating is corroding badly in the humid atmosphere. The metal under the gold layer on a DIMM is Copper. The metal pins of the CPU are likely to be steel.
Copper corrosion is called Verdigris and has a bright green colour. Check your DIMMs to see if the corrosion is light green.
Steel corrosion is called rust (which you already know) and has that familiar brown colour.
The corrosion on your DIMMs and CPU may already be too far gone to clean off in the hope the components will still work perfectly.
Since you're unlikely to seal off your computer room completely and keep a large dehumidifier running 24 hours per day, the only other thing I can suggest is to install a small heater inside the computer case.
This may sound totally mad, but raising the temperature inside the computer roughly 5 degrees above room temperature (when the computer is switched off) will increase the amount of water that can be held in the air before condensing out.
Low wattage heater elements exist, but as an experiment, try fitting a 12V car tail light bulb (with Tungsten filaments) inside the computer case (carefully), then replace the side panel. These bulbs come with two filaments, 6W (tail) and 21W (stop).
Start off with the 6W filament running inside the computer and leave it switched on whenever the computer is not being used. Switch off the 6W bulb when you're actually using the computer.
Check for corrosion on a weekly basis. You'll need to find a 12V DC supply for the bulb. I'd use one of those 12V 1.5A power bricks you get with external 3.5in hard disk drives.
If you're very lucky, the heat from the bulb might reduce condensation inside your computer, but the best thing is a room dehumidifier.

If you're facing humidity-related problems with your PC, and ventilation doesn't seem to be resolving the issue, it's perplexing that only the connecting points are rusting while other components remain unaffected. It's recommended to consult a PC hardware professional to diagnose the specific problem and find a suitable solution. Their expertise can help prevent further damage to your PC.
