I buyed DELL Optiplex GX270 just six months ago.It was intel P4 with
2.8GHz.When I try to ON my PC yesterday I recieved an orange light on
my monitor and green on my CPU...nothing else...even not "DELL's title"

..Computer man said that IC is burnt...cannot be replaced...he said all
the processor is
useless now...so what can I do now?
