Upgrading for windows 10

[Striferx1]

I have an old HP Pavilion dv9000, I had stopped using it years ago due to hard drive issues and loading.  I had totally forgotten about it until recently, and was able to upgrade it from Windows Vista to Windows 10 and it loads super slow now, or it doesn't load at all after I uninstalled some items.  I'm guessing because it's super old it's due for some type of upgrade.  What would I be able to use for a processor, RAM, memory, etc for it?  Also note for se reason when I plug I'm a external hard drive and boot up it up it freezes.

You're talking about a 12+ year old PC -- and I am surprised it works at all with Windows 10.

Apart from (maybe) adding memory, you're not going to be able to do any hardware upgrades to make this PC anywhere near a current device.  And I'm saying maybe on the memory because that is so old, you will have serious problems finding anyone that still sells the model memory needed.

You also said you uninstalled some stuff?  Why would you do that if you're going to risk trashing the ability for it to boot?

You say it loads super slow -- that could be for any number of reasons, not the least of which is it was not designed to work with Windows 10.  

You said you had hard drive issues -- so did you replace the drive? Or did you just force Windows 10 onto it?

I have an 8-year old laptop that I have cherished but it won't run Win10 hardly at all, so I had to scrap it.

Yeah I was surprised it was working, actually I put windows 7 on it and figured I'd try windows 10.  It does take a bit longer to load up but seems to run it.

The item I removed was microsoft office 2007, which I don't think would affect it.

I had replaced the hard drive, but that was years ago.  I'm honestly surprised this works at all.

I've noticed even when it was on vista, if you plugged a usb in it or external drive in one of the ports it still refused to login it would just freeze on the windows loading screen.
