I am a computer ignoramus, whose knowledge of computers extends to switching the thing on and off unaided. I bought this T510 some years ago (Windows 7 Professional 64-bit) and it worked perfectly satisfactorily, until I made what appears to have been a fundamental error - I "upgraded" to Windows 10. "Degraded" would be a better word. The thing now takes ages to react to anything. It is just soooo slow that it has acquired the usefulness of a chocolate teapot. I can't see any posts relating to this particular subject on the forum, although I see members saying that 10 works fine on their T510s. What am I doing wrong? Or is it just my incompetence that's letting down the side?

Probably your hard drive is at the end of life. Please download CrystalDiskInfo and provide SMART properties.
Moreover it's also possible, that you have only single memory module or insufficient memory capacity. You can check it using HWiNFO:

I see two problems:
- Your HDD disk should be replaced as you have pretty slow model (5400rpm/8MB cache), which probably have some wear level. SMART don't shows all problems - especially performance issues. I would advise replacing it with SSD, e.g. Samsung 850 EVO 250GB and install Windows 10 on it. Regarding old disk, you can buy a caddy/Ultrabay adapter and install it instead of DVD drive.
- You have only 4GB RAM. Please do note, that your integrated GPU doesn't have it's own memory. Instead, it can allocate up to 1.5GB - 2GB RAM, so effectively only 2GB is left for your OS. Opening many apps or simply tabs in web browser could allocate all available RAM. When this happen, OS starts to utilize HDD as a virtual memory. This severly impacts OS perfromance, especially on slow HDDs. Increasing memory to 8GB should improve the situtation (it's maximum supported by i5-480M).

So I started with replacing the RAM under the base with the type you suggested (there's another under the keyboard, which I left in place) - and promptly moved on to another category of problem, from the computer that works slowly to the computer that doesn't work at all! I am confronted with the dreaded Windows 10 BSOD, with the peculiar message "STOP CODE: IRQL nmot less or equal". I have absolutely no idea what that means. What have I done wrong?
