The computer is a custom build. I have an Altec SLK1650 case. I am trying to track down a problem. If I can get the computer to start the computer works fine. When I press the button to start the computer it will make the appropriate sounds but within 1 second the computer dies. If I press the start button repeatedly it will act like it is going to start for progressively longer times until it finally it continues running. At this point the operating system is not running but the fans are running. I then push the reset button and then the computer start starts normally. I replaced the power supply (350W) with a 450W but that did not help. At this point the computer will not start at all. If I hold the reset button in and press the start button the computer will sound like it is running but will not boot. When I release the reset button the computer dies. Just wondering if it might have something to do with the start or reset buttons. Any suggestions will be greatly appreciated. Thanks in advance for the help ... Michael You didn't describe the hardware. Make sure the CMOS jumper is set properly. I would assume that the CMOS jumper is set properly because the machine has worked and nothing was changed. I misunderstood. I was watching Tony Bourdain and making posts during the commercials. In future I must do one or the other but not both. What other bits is this PC made of? Thanks for the Reply ... the components a Motherboard Foxconn 915M03 Intel P4 540 3.2GHZ (I think) the only numbers on it are 35505002 A2493 NVIDIA GeForce 6600 LE soundcard ATX Ver 2.01 450W power supply SATA Western Digital Hard Drive 200G Altec SLK1650 case You didn't specify what is ram type, maker, amount and number or DIMM's? If I understand correctly the PC worked properly for a time (possibly a brief time) and now completely refuses to boot. May (or may not) help me to know how many hours, days or months it functioned properly. I doubt the buttons are a problem but you may be able to remove the front cover of the case and push the switches directly just in case there's a mechanical problem with the front cover. IIRC the switches are of the momentarily on type meaning that they complete a circuit only for as long as you keep them depressed. You can unplug them and test with a multimeter to verify if they are normally open when not depressed and closed when depressed. Read manual and verify that all power connections and case connectors are correct. The MOBO is in the discontinued list at Foxconn:http://www.foxconnchannel.com/produc...make_list.aspx Link to Foxconn 915M03 page:http://www.foxconnchannel.com/produc...il_overview.as... en-us0000089 Link to manual:http://www.foxconnchannel.com/suppor...aspx?ID=en-us0... Read manual, determine what options are on MOBO. Reply back with full model number including suffix. Try each of the following steps one at a time booting after each step (unplug power cord before removing/installing hardware or jumpers)(use grounding strap and observe ESD precautions): Remove all boards except VGA (disregard if VGA on MOBO). Then boot. If multiple DIMM installed remove all but one. Then boot. Put in one DIMM then boot. Repeat step with each DIMM singly booting each time. Unplug all but boot drive. Then boot. Enter BIOS and choose Load Fail-Safe Defaults. Then boot. Reset BIOS. Be very careful not to power up before placing CMOS jumper in normal run position. Then boot. Remove processor heat sink and look for thermal paste. If none found then remove processor and inspect socket and processor for damage. Apply paste as needed, reinstall heatsink/fan then boot. Reply back with your results. I am fighting a particularly pernicious problem of my own with a CD burner that corrupted my backups so I may be slow to respond. -- pcbldrNinetyEight -- pcbldrNinetyEight The computer has been working for a couple of years. 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 |
