Make sure on-board speaker is plugged in. Reboot. Any beeps? If so, add items back one at a time beginning with one RAM module. If not, try re-seating the CPU/fan using thermal adhesive.If it still makes no sound, suspect CPU or MB. Also, if you can get a POST reader card and insert it into the clean MB and then power up, this could show the real problem. + 0 Votes In this case I would zlitocook 7 years ago Find out who made the mother board and visit their website. Some MB have spefic ways to install and use them, like when installing new drives you need to access the BIOS and tell it what kind of drive you have installed. If you do not do this you or you try another hard drive, you need to clear the BIOS by moving a jumper. Read the install FAQ and look at the info on the CD to be sure every thing is ok.

I suspected the power supply and replaced it with my test supply (which I know is good). With the test supply the machine seems to power on, but there is no beep and the it ignores the 5-second-power-button-hold-down. I tried it with yet another power supply and I experienced the same problem. The machine only seems able to boot with the power supply that it came with.
