Matt Posted June 1, 2008 Report Share Posted June 1, 2008 I was over at my girlfriend's house the other day and they were telling me about this old computer they had that they couldn't get to turn on. After some investigation, I discovered that the issue was just their power cord--a simple fix. Brought over a new power cord, and the thing booted immediately. Now however, something odd is occurring. They tell me that every time they shutdown the computer, it will reboot instead of turning off. I tried it myself, and this is exactly the case. Every time it just reboots. I'm not sure if this is a hardware issue or not.The computer is running Windows 98. Thanks,Matt Quote Link to post Share on other sites
shanenin Posted June 1, 2008 Report Share Posted June 1, 2008 You could try booting it with a live linux cd, then shut it down from linux. This would tell you if Windows or hardware(bios) is the problem. Quote Link to post Share on other sites
TheTerrorist_75 Posted June 1, 2008 Report Share Posted June 1, 2008 I remember that problem.Go to Start > Run > type msconfig, press the <Enter> key, click on the Advanced button and check Disable fast shutdown. Quote Link to post Share on other sites
Matt Posted June 19, 2008 Author Report Share Posted June 19, 2008 Now I'm thinking this is a hardware issue. Sometimes it doesn't turn back on; but after shutdown I can hear a very high-pitched squeal coming from the PSU. Quote Link to post Share on other sites

Pete_C Posted June 22, 2008 Report Share Posted June 22, 2008 First thing I would check is boot to safe mode and try to shut down from there. If it shuts down you know it is a problem with something which loads in normal windows (software or driver) which is crashing so badly when it is told to close that it crashes windows too. Normally this is a driver (generally sound card or video card) but it could also be a virtual machine like antivirus.But I agree, that if you hear a whine from the power supply it is probably a capacitor . It is possible that the power supply is at fault. Modern power supplies are switching power supplies, they are not supposed to totally shut off, certain traces on the motherboard are constantly energized and the momentary interrupt switch on the case connects two which trips a solenoid on the power supply. Boot to the bios, and see if resume on power failure or similar is enabled. If so disable it. Possibly if the power supply is failing when told to shut down, when the solenoid is tripped the voltage to the motherboard power management circuits is interrupted and when it resumes the motherboard bios tells the power supply to switch back on.
