GA-7VTXE+ Rev 1.0 Bad capacitors and bad mosfet
Three capacitors were leaking on this board (the three in a row behind
the audio jacks), so I ordered replacements and soldered them on the board. Back when the board failed, it somehow fried the logic board on my wife's hard drive. Now, there are two MOSFETs very close to the capacitors that I suspect failed. The plastic is a bit melted on the top of them. Unfortunately, all I can make out is that they are a NEC part that starts with the letter "K". The mystery MOSFETs are labeled Q57 and Q60. When I try to power on the system, it acts like there is a short somewhere, e.g. the CPU fan spins around a few times, and the amber led comes on near the ATX power connector. Then, nothing... And this is running the board in an isolated environment, without any peripherals attached. Can anyone out there with this board take a gander and see what the numbers are on these MOSFETs? Any detailed insights into whether they could cause this problem would be appreciated as well... Thanks, Eric |
