Solid Hardwood, Engineered and Laminate Flooring - Floor Squeaking in Summer !!!

My hardwood floor squeaks a lot from different places and I can tell from walking on those specific places, it has lots of flexibility at different places which really gives out squeak noise. My stairs also gives lot of sound when we go upstairs or downstairs. In winter it was so bad but it got much better when I ran humidifier in January. Now at this summer time, I run dehumidifier in the basement and I run my AC a lot in this summer season,could it be a dry air inside my house that is causing this. It is quiet humid outside this season. Is there any repair that could be done to those specific spots that I mentioned?

Thanks

Can anybody please help !!!

Without actually seeing it, I cannot determine from my computer monitor, what is actually happening to cause the excessive movement.

Any more suggestions ?

I think Perry is the top floor pro here, so if he can't figure it out online, I think you're best bet would be to have a couple handymen come out to your house and give you their opinion on-site.
