Question Time to replace old faithful - New or refurb?

[kep55]

Back in 2008 I built my 2nd PC. Here are the specs:
Product Name: GA-MA770-UD3 (1.0)
BIOS Ver: F9G
Brand: Nvidia pci x16 500mb
Model: Athlon 64 X2 5200+
Operating System: Win 10 64-bit
Brand: Kingston DDR2-667
Size: 16 GB
Power Supply: 800w
Memory Part No.: KVR667D2N5/4G
HDD: Western Digital 500GB
Monitor: TCL 6-Series 55" via HDMI

I currently use it with win10 24H2 19045.5371for web viewing, scanning photographs into my NAS, using a Fujitsu fi7140, online meetings, and word processing (LibreOffice). Obviously I don't need to get a Ryzen 9000X3D pumping thru a Radeon 7900 XTX and 32GB Kingston FURY Renegade Pro DDR5 RDIMM.

Anyway, it's taking up to 5-6 minutes for the kit to boot, and compared to my ACER TC-875-UR15 which replaced it, it's become a real bowl of molasses in Norway. Firefox for some reason won't load anymore, and forget about getting Zoom running. I don't use it that often so I really don't think a new box is necessary. And I'm cheap.

Any suggestions what I should keep in mind for getting a replacement? I'm leaning towards a refurbished unit five or fewer years old.Thank you.

Maybe for this system, a full wipe and reinstall is in order.

Hardware rarely gets slower. The software, however...
