Sorry Sevenor, getting mixed up with Office & Windows - it's all this crazy stuff that's been going on, it's addled my brain!
Not only did the shortcuts on my desktop turn to an icon showing a blank page but the calculator & games disappeared from my PC. they were nowhere to be found in programmes/accessories, etc.
I finally put my old Windows XP Pro disc in & added windows components - that brought them back again.
Also, after a lot of messing about, I have managed to get my printer working again.
Paint Shop Pro X still won't work & it won't install either. I keep getting a message saying it can't find a file (this file has a lot of numbers in it & is very long).
So I seem to be nearly full circle & back to where I started with a slow PC that thinks about it for a time before it opens anything and with the added problem of not being able to use PSP.
Thanks for all you help.
