Gateway2000 won't power up

[TZ]

When I press the power button nothing happens. Was working last week and nothing has changed. Any ideas on how to troubleshoot this? Thanks.

Make sure power plug is in wall socket before depressing power button.

Unplug everyone from the PC, Then hold down the power button for 30 secounds // If the modem is still intalled remove it this is a common problem with Gateway/eMachines dunno about any other PC but normally will fix the problem
