When you are not lucky

as i am, nothing work on my system, when beos did years ago (HP xw6200 2xeon 3200, ati firegl 7200 2screens IIyama prolite b2409hds and packard bell 19inches.
mouse even don’t work!!! (basic logitec)
packard bell is warning “fequency too high” i had to swich off.
prolite is only on vga (strange for 24inches)
Then nothing to test or even try to see working.
Better years ago it’s a pity but CTL-alt-Del works fine.
