Okay, yes it's an older computer, but it's a workhorse & I do everything on it (or I did).
And it uses Windows XP Home SP3. Please forgive me.
Recently, I start the computer, it gets to the main page with all my shortcuts/folders/programmes on it, and it either freezes, or I get "the Blue Screen" and have to reboot - every time now. I'll open a folder or start a program & after a short while, the PC freezes or the BSOD appears. Ad nauseam.
