Your script works for me. Maybe the addition of a bit of code will help you see what is happening at the end of the script. You need to remember that STDIN is line buffered, so if you select 2 for example, you still need to hit a Return for it to be read by $question = <STDIN>;<p>If you want single key responses, see [id://986955] , where you don't need the Return key to capture a keystroke.
<c>
#!/usr/bin/perl -w
use strict;
my $question;
my $computer;
my @pc = qw(comp1 comp2 comp3 comp4 comp5);
# Find out which computer to cold start
system("clear");
do {
print "Which computer would you like to cold start?\n";
print "1 - comp1
2 - comp2
3 - comp3
4 - comp4
5 - comp5\n";
$question = <STDIN>;
chomp($question);
} until ($question >= 1) & ($question <= 5);
$question--;
$computer = $pc[$question];
print "$computer\n";
print "Hit Return to continue\n";
<>; # wait for a newline
</c>
