Hello All
Rig has been shutting off randomly for a couple months. I have 2 processors, Athlon XP 2500+ and XP-M 2400+ 35W. Neither will POST at all now so I can't get into the bios. I reset cmos, changed battery, swapped PSUs, swapped memory. The Chaintech 7NJL1 board is now out of the case with 1 stick of RAM, speaker, CPU HS/Fan and PSU hooked up. I jump the switch pins to turn on but still no POST or Beep codes. HS/Fan must be installed for power to stay on. The board is/was a great OCer but never ran it HOT for very long. There is no sign of bulging capacitors on board. The only physical thing I can see wrong with the board is the paint is off of a couple traces under HS clip. Maybe one or both of these traces are broken? This is a nForce2 400 chipset and when I installed the XP-M 2400+, it reverted to 6.0X multiplier no matter what you set in the bios. So, I tried an L12 Mod using the wire in the socket method. This is when the problems seemed to start. I think I fried a 450W PSU in doing this. I replaced with another PSU (Lower Wattage) and voltages all seem to check out except maybe the Gray wire which is at 4.25V, a little low. I think I have it narrowed to either broken traces, a shorted socket from L12 Mod and/or Low Voltage on gray wire CPU signal.
Any help would be appreciated. If I need a new board, I will be looking for a good Socket A (462) Overclocker at a better price, lol.
Also, board seems to be energized, just won't POST.
Thanks All...
