Please Help - Computer won't turn on

[kento46]

Ok, my computer was sitting in my room, it's been running fine for a few months now. A couple hours ago, I tap the front of the case with my foot, and everything just shuts off. I tried turning it back on and nothing happened. So I turned the power supply off and back on and tried again. This time, it tried to start and then immediately shutoff again. The power supply has a blue light in it and that goes out immediately as well. I can see 2 yellow lights on the motherboard are lit when the power supply is turned on. Do you think my power supply blew or is it something else? Any way I can test?

Sounds to me like you disrupted something when you "tapped it with your foot". You might have knocked a fan out of place, that would make it overheat, and therefore, not boot.

Not sure what a "tap" could screw up.

I guess I'd start by checking the seating of all the cards and memory in the computer in case you knocked something loose.

Also make sure you didn's somehow jar the cpu heatsink off of processor die.

After that I'd look at the PSU and test the computer with another power supply if you can get your hands on one

It sounds like you shorted the front panel wires. check that first. then unplug your front panel wires from mobo(led, hdd led, reset switch, power swithch) and just plug to mobo the power awitch see if starts. it also be a good idea before starting, take the battery out and wait 5 minutes,then clear CMOS by putting jumper to clear cmos position(most probably 2-3 pins).Also check your power supply and make sure that it didnt tripped to 220v hitting against something when you kicked the front panel.
