I tried to upgrade to windows 11 but it said my pc cant run it as i dont have TPM 2 and a processor that is not compatible. Is it cheaper just to get a new PC or to get compatible hardware then purchase windows 11?
Not an expert but I would think it would be cheaper to relpace the internals yourself but easier to buy a new one. Althought a new one will probaly have the latest software already installed.
What OS are you running at the moment. You can upgrade (not an upgrade in my opinion but MS says you have to) on older machines if you are able to use programs like Rufus. There is a myriad of information on YouTube. I "upgraded a 20 year old laptop yesterday so it can be done. but if you use the method described on the Microsoft website it will not work. get Rufus, https://rufus.ie/en/ and download the Windows 11 ISO from Microsoft, and go from there.
Depends what you use it for. But if just for home use (emails, browsing etc) then you can't go wrong with "renewed" ones on Amazon. They have Dell optiplex, 8GB RAM, Win11 installed, intelcore i5, for under £100. You get 3rd party Amazon backup (check the small print but I assume 30 days warranty). Less hassle and probably cheaper than buying your own internals, given that you might need more than just a screwdriver
