I went to bed last week as normal and shut my computer down. Nothing was different about the computer until I got back from school and it wouldn't boot. I would press the power button and nothing would happen, no sounds or anything. After hours of messing with the computer and disconnecting and reconnecting cables it still wouldn't work. I decided to buy a new power supply and install it. I plugged all the needed cables in, the 24 pin to the motherboard, the 4 pin to the motherboard and the pins to my optical drives. I pressed the power button and still nothing happened. I honestly don't have a clue what do to and am frustrated to the point of tears.
