Default Hopefully some can help me?

Ok this morning I unplugged my XPS 420 to clean it for dust ect and when I went to reconnect it plugged everything up right the computer now wont even come on. Now the green light comes on in the back for the internet cord and the light is coming on in the back as well as the monitor works but when I click on the button it doesnt come on and it just blinks yellow every 5 to 10 seconds, i went to hook it up in another room and the same thing. Can someone tell me what might be the problem and what I need to do to fix it.

Thank you

Unplug the power cable, leave it unplugged for a full hour. BEFORE you plug it back in, repeatedly tap the power button for about 30 seconds. There's a good chance that will get you back up and running as it resets some of the power circuits ( by discharging them ). The problem may reoccur though.
