This is a new problem. I have not made any changes to the hardware recently. The only thing that I have done recently is restore a saved image to the boot drive. That worked fine for a few days. The symptoms came on slowly. At first it only took a couple of tries to start the machine. Later it took more tries. I then purchased the new PSU and it booted on the second try. Now I can not start it at all. I will test the memory as described but I am not sure how to work with the BIOS particularly with the inability of starting the computer. Thanks ... Michael |

Michael Press and hold down the delete key to enter BIOS immediately after powering up the PC. Does anything ever appear on the screen, if not can you swap out the VGA? Can you swap out the monitor or try it on another PC to verify that it works? When the PC starts you should hear only one (faint) beep. If you hear more than one beep then how many do you hear? If you hear multiple beeps let me know before you proceed with the following steps. Unplug the hard drive and do whatever you can to get the PC to turn on and stay on. It won't boot but you may be able to enter the BIOS and set it to fail-safe setting. In the manual I read that there are several settings that can shut down the system therefore you need to set it to fail-safe. As an extreme last resort to enter the BIOS I would leave the HD unplugged and remove the processor and then power up the PC. -- pcbldrNinetyEight |

Michael Well the way I work it is that I try everything that I can and then give it to someone that has the resources to track down the problem. That would be a repair shop. I ended up replacing the power supply and the motherboard. One interesting side note: Those vertical "barrel" shaped things on the motherboard of which there are a couple dozen. Well the ends appear to be aluminum and have a score mark on them. Most are depressed into the "barrel". The repairman pointed out two that were starting to expand out. He said those were bad or going bad. Anyway the computer is working. Thanks for all of the help ... Michael |
