a while a go i was having a clean out of old programs and stuff i dont use on my pc, and only just now my pc has occasionally crashed and the screen looks as if its safe mode, with the icons large and discoloured, also the pc freezes and then beeps when i open a windows media player file on a website and when visiting youtube i cannot watch videos in full screen as the pc crashes.
is there any way i can find out whats missing? or can anyone please help!?

many thanks!
