yes hayoung The w key went faulty during gaming, i just think the cherry mx died, thats the first thing comes to mind. I have not opened it yet....

my corsiar k95 has 1 faulty key, out of warranty the W sometimes dont register. is it possible for me for soldering a new cherry switch on it? No visible screws at the back, it seems they are under the rubber feet.

Backstory - can skip - I have a down draft cooler on my i5 4460 and b85. 1/3 of the cpu fan broke off but was still spinning most of the time, however, the uneven spin wobbles the whole motherboard. Sometime the fan would not spin, i figured it was ok for the time being. if its gets too hot, it should shut itself down. This went on for a few days. Then the mobo would boot up, but no display signal, internal +external. I have another pc to test everything, except the cpu, mobo and ram. how to determine if cpu or mobo is broken???

Im using ax370 gaming k7 gigabyte, with ryzen 1400. Im stuck on bios F31. the EC FW update just crashed my PC, is it supposed to work? I need bios F40 for 3rd gen? can I ever use 3000 series on my motherboard? I havent tried 2nd gen yet, im currently looking for deals.

what is the active ingredient that cleans metal oxidization? coca cola acid does the same job?

the prices i listed are for functional cards. Im more concerned if the heatsink can be made normal again.

i have seen white spots on gpu heatsink that are sold cheaply. They are oxidized aluminium ? Are mining cards prone to this damage, and what other visible wear? all cpu heatsink are made of alu ? Can they be cleaned and recovered? ie. rx570 under $20usd gtx1060 6gb under $90 gtx 1070 (pictures, showing the worst parts) under $170 assume all with 1 year warranty left

This is just a cheap used monitor 20’’ i picked up for $12usd. I have 3 4K monitors but I don’t have enough knowledge and experience....
