@crashOH -- welcome to this peer-to-peer discussion forum, where volunteer contributors try to help.

I hope that they did not charge you much for NOT solving the problem.

also microsoft tried to diagnose it remotely uninstalling chrome and firefox and reinstalling.

Note that since January 2020, both Google Chrome and Microsoft Edge have been built on the same "basic" open-source software.  So, there are very few differences between them. 

Firefox is still an alternative, but, personally, I see no value in installing/using it.

internet provider just installed a new modem and router.

That should not have made any difference.

still, internet crashes repeatedly I report each crash and restore. no one can help.

someone said it could be Ram or graphics card.

Yes, you could have a "hardware" issue: RAM, power-supply, motherboard, graphic card, processor, or overheating.

Or, you could have a "software" issue.  

another wants to remove all and reinstall. 

The first thing you MUST do is to backup all your Personal Files to an external device, such as a 64 GB USB memory-stick ($10 to $15) or to an external disk-drive ($50 to $150), before doing anything "drastic".

Windows 10 has a "reset my PC" app, that will reinstall Windows, while preserving your Personal Files (if you tell it to do so), assuming that you have "fault-free" hardware.

So, that advice, although skimpy, is a possibility.
