Good morning, I have a problem with my DX58S02, black screen, not beeps, 1. fan go on, 2. tested the PSU is ok. 3. did disconnect the AC power when I took it apart. I stripped the system down to bare case, with only the PSU, HDD, and the disc drive still installed. After I re-assembled everything, and connected all the pins and cables, including the 4-pin on the mother board. I connected AC power and tried to boot the system, but there was no beep and no video, even though the fans are turning, and still don't working.?
2 weeks working without luck.
