GA-7VRXP mobo killed or just comatosed?
Hello all. Hope someone can help. Last weekend I was in the process of
upgrading a friend's PC. First job was to replace an ageing, noisy 250W power supply unit. The replacement was a 250W unit I had recently taken out of a PC at home and had been in good working order and clean. When I put the power unit in my friend's PC and powered up, the unit went up in smoke. A gradual burning, not a sudden explosion. Needless to say I quickly disconnected the power supply. The PC was booting up as normal when I disconnected. I had not made any hardware or software changes by this time. I put the original PSU back in and found that the PC was practically dead when I tried to switch on. There were no signs of life except the little LED near the mobo ATX power connector responding as normal to power on/off. Also, the keyboard lights flashed very briefly. The CPU and PSU fans did not move. I've tried everything I can think of to resurrect the system: disconnected all drives and cards from the motherboard, reset the CMOS, removed the battery for a couple of hours. Even replaced the CPU with my own. Still nothing. I can see no damage to any part of the board (burnouts, fried capacitors etc.). Do I have a dead and useless board or is there something I may have overlooked? Any help will be greatly appreciated. Paul Armitage (Self-explanatory anti-spam reply address) |

Tried that but it didn't work. The only sign of life in the motherboard is the little LED near the ATX connector. I've tried progressively adding things to the motherboard, from the CPU to the full complement of cards and drives. Still no life. |

Try removing the board and cards from the case, I had a similar problem and it turned out to be a short circuit between the case and board... |
