After my computer is idle for a few minutes (maybe 15-30 minutes) it goes to the windows screensaver (the grassy field) and locks up. At that point, I can't do a ctrl-alt-del. I can't tap the power button to resume.

I have gone into power options and selected "always on." "Never" turn off hard disks. And "Never" on system standby, but this still happens. I have also disabled the "hibernate option."

Please help quickly

That isn't a screensaver, love, that's called 'wallpaper'. There is no
screensaver of a "grassy field" (and what's a field if not grassy?)
