are u sure it boots up?

do get a "beep" sound, and can u see the CPU fan running?

if u can only see the fan running, and no beep sound, then its different problem
but you need to give little more details. Wat exactly did u do after changing your cabinet?

i am not being system specific but 7200gs since its a graphic card

connect the moniter to the onboard display and change the display option to the add-on card from the BIOS it should work

well i just took out the whole setup and put it in the new cabinet.now the cpu fan runs.but there is no beep sound and no display.......
neither from the graphics card nor from the onboard vga........

what is the prob?
