Processing speed

[Jeremy44]

I have an old HP Notebook that still functions but very, very slowly.  I've loaded updates and already performed the HP Diagnostic online.  No problems showed, however the computer can take a long time, up to minutes, just to open a file or program.  It also freezes for a short time intermittently, such as when writing in Word.  Is it possible to improve the speed?   If so, how?  Thank you.

The specs of your machine is

          https://support.hp.com/au-en/document/c04493615

It has slow CPU, slow disk and small RAM. Due to mall RAM therefore system will page/swap to disk which causes the slow disk spinning to dead. My suggestion

1. Increase RAM:  It only has 1 slot of RAM, you can replace existing 4G with 8GB (max) using the following compatible RAM:

2. Upgrade HDD: Because you can't add more RAM to more than 8GB, you need a faster disk. You can upgrade your slow  1TB 5400RPM hard drive to 1TB 2.5" SSD using the following compatible drive
