Hi, Just thought I would post this out of desperation. Here is my situation. I build my first computer two days ago. It worked, it ran for seven hours or so. Then the next day it randomly shut off so I thought it might have been due to the heatsink fan not being properly installed. So I reattached the heatsink and place everything back together. Now it will not even start, no fans going on any peice of equipment. It will not boot up period. The motherboard lights come on but thats it. These are the things I have tried. 1. I Bought a new power supply to see if mine was an issue. It would still not boot up. 2. I have made sure all the cables were plugged in correctly. 3. I tried booting up with nothing attached but the heatsink and cpu and still a no go. 4. I was going to try removing the battery on the motherboard when i got home and reattaching that. 5. Did my cpu burn up because my fan wasn't on correctly? I think it would at least boot up if it was.. 6. If the motherboard is dead, I can exchange it. I just want to make sure I have done everything I could to figure out why it will not start. Not sure if anyone could give me assistance but it would be great if anyone could help me.
