Hi, my desktop was working quite fine, till I started trying to burn a disc. Then the system froze. Tried to restart it several times...even unplugged the system...but the computer did not fully start. Now it refuses to power on. I tried another power supply, but it still did not power on. Also checked the RAM to see if that was the issue...still nothing. Does this mean my motherboard is gone? Please note that when I plug the power supply to the board, it does light up, but still does not power on.
