Hey,
I recently saved up all the money i needed to put together a good gaming rig for myself...its a pentium 4 in a asrock motherboard...with a 480 watt psu that came with the case i got. I put everything together and had no issues....but when i plugged it in and hit the power button absolutily nothing happend except for a small blue light on the case came on. no fans, no hard drive noise, not even the psu made noise. i plugged my old computer in to the same outlet and it booted....so i know for a fact its getting power....and the fact that the light on the case goes on tells me it has power. Any ideas?
