MSI 1996 Motherboard: Power on Signal to PS staying high
P-ON should enable 3.3 &12v to Motherboard when start button is pushed. The signal stays high and if i disconnect it and put the ps side down to 0v everything is fine PC works beutifully. Only drawback ps and fan remain running following normal PC shutdown. I have noticed the abscence of any audio from PC.

Check the cable between your monitor and computer. If this is a new install and you have added a graphics card, you will need to boot up once using the on-board VGA. Doing so will allow you to turn off the on-board VGA in the BIOS. Then you can shut down and move the monitor cable to the new graphics card and reboot.
your motherboard is bad. Try the following before RMA'ng it.
1. Remove all the cards and memory.
2. Recheck your power supply connections
3. Remove, clean the thermal paste and reapply new
thermal paste (follow the manufacturer's directions)
4. Reseat the CPU.
5. Install one stick of ram
6. If the motherboard has an onboard video connect your monitor to it.
7. Try powering it up.
If that works, add the rest of the memory a stick at a time. If the system continues to power up, then install the Video card, and test again. Finally if everything is functional, chalk up the previous problems to bad karma. If the system fails to power up, and stay powered up after adding a component, then that is the faulty part.
Consider the location of the clicks you heard. The hard disk drive (s) are quit close to the power on button. These clicks could point to a bad hard disk drives spindle or a poor wire connection at the power button.
In either case the first question is did your hear your system P.O.S.T.?
Before you lost display! Normally, if the CPU gets too hot two things happen. 1st your hear what sound like a siren from the internal speaker & than the CPU will shut down the system so the CPU doesn't fry. If there is a problem with your power on button, AKA clicking. Check the wires from the button to the motherboard. Make sure their isn't a bad wire. There's only 5v DC running to the power on button. I doupt you'ed even hear a 5volt short.
If you have an OHM meter you can check the on button. You'll need someone to press the power button off & on. Do this with the power supply unpluged. Your checking ohms not volts. If possible check your drive (s) in another system.
Hi this might not be a motherboard problem. Remove the memory card and clean the contacts and reinstall it. If this will not work for you replace the memory card with the same type you have in your computer. Hope this info will help you solve the problem
well this is one of the nightmare problems I keep got into ..there can be alot of posibilities..but the most common are the video card is damdaged or the mainboard.try to change the video card and check than.if the problem persists,than is a motheboard fault..look to all the condensors,chech the intefrity of your connections.. good luck. it is a very booring work.
Do you have a modem plugged into phone line - is a signal on phone line causing it (unplug phone line cable to try that). Could be faulty power switch on front of computer where the contacts are only a hairs breadth apart and the slightest movement/vibration causes it to contact (try this by disconnecting those two wires from the motherboard
I'd try disconnectng any communication cables from the computer first. That would be LAN and Modem cables. If it still restarts, disconnect the keyboard and power down the PC. If it still restarts, then power down again before it is fully off, remove the mouse. If it still does it get a priest to do an exorcism
Either the new power supply you purchased is not functioning correctly. But, assuming it is now that you are getting some form of power to your PC, it is very likely the motherboard. Whatever fried your old power supply (or it could have just been the power supply itself) most likely fried your motherboard in the process. Probably not the CPU since the MB can't even post.
