Damage to a liquid-filled computer case
Damage to a liquid-filled computer case
Yesterday while playing at my desk, I accidentally spilled blackcurrant squash all over my computer. I shut it off right away. Upon checking, the damage has reached the motherboard and GPU—my GPU is getting broken apart, which is something I should avoid doing at home. Should I try fixing it myself or call a professional?
Hey, perhaps capturing a photo of the damage would be helpful.
This was the optimal choice. Once you thoroughly cleaned all components from the PC and allowed it to dry for roughly 24 hours (48 if you wish for added security) in a dry setting, you can restart it and test its operation. The positive sign is that the device appears to have been powered down prior to any issues, reducing the risk of damage and helping preserve essential parts. Removing the GPU is generally straightforward; many units only require four screws to secure the heat sink to the board, making cleaning easier. You might also discover a specific tutorial for your exact graphics card model. Keep in mind you may need to apply a small amount of thermal paste to the GPU die before putting it back together.
Take apart and clean each part thoroughly, then put everything back together. If you're okay taking off the GPU heatsink, do so; otherwise just wipe it down. Use compressed air or a hairdryer to remove any moisture or liquid from the heatsinks and PCBs, cleaning each component before letting it dry completely. Apply alcohol wipes or isopropyl alcohol with a microfibre cloth.
If you don’t need the PC, simply allow the damp sections to air out. Since it’s summer, this won’t be simple for all components—like if moisture enters intricate parts such as the GPU. Let it dry longer, ideally on a balcony or any spot with direct sunlight if possible. This was the initial crucial step and it turned out to be a success.
remove the device to clean dirty components by soaking them in water to dissolve any grime, ensuring you remove the CMOS battery and heatsinks from the motherboard, as well as the GPU heatsinks. Allow it to dry for a day or two or take it out once it’s completely dry (usually 12–16 hours).
Black currant juice has a relatively low pH. It's best to filter it thoroughly.
Please verify this suggestion—could you confirm if removing the motherboard along with all components and the GPU would help? Soak the parts in water or alcohol for 48 hours, then dry them.
That's exactly what I recommended. For boards that aren't functioning properly, dirty ones actually perform well. Water works fine. Using alcohol such as 99% IPA is better—spray it directly on the board instead of submerging it. Dumping fuel into a spark could cause a fire, which isn't ideal. The fumes and smell are noticeable, but after testing, spraying helps effectively. It's usually enough to wait a day for simpler issues like dirty PCIe or RAM slots; just spray and leave it for an hour or two.
