Re: dead mother board
The problem with power surges, or low power (brownouts) causing excessive current draw can cause multiple problems to motherboards. Even if you were to pinpoint and repair one problem that appeared to fix the fault, several other components on the board may have been weakened, and prone to fail.
If you are certain that the power supply is 100% ok, then replace the MB.

its most likely either your power button or power supply having an issue ensure the power buttons wires are all connected correctly as per the key for the motherboard and if its still not starting try using a different power supply if its still not working than its most likely a dead motherboard
ELECTRIC SHOK OR IMPROPER EARTHING IS DAMAGE POWER SUPPLY,MOTHERBOARD,PROCESSOR,RAM
HOW TO CHECK IT.
(WHEN CHECKING KEEP CAUTION :- REMOVE HARD DISK DRIVE POWER SUPPLY SOCKET)
1. check power supply watt 400/450 and same another power supply install and check it. if power supply change and system is working ok so problem in your power supply.
2. check CMOS cell on motherboard,(3 volt)
3. Bfore power supply changing check on mother board any capasitor is like as damaged or not.
OR check main chipset ic is marked as intel.whenpower on it is very hitting or
normal)if very hitting require to repair your motherboard.(intel chipset ic near cmos cell or pci slot,)
4. checking of ram on other pc (working or not)(one beeps coming or not,if one beep coming ram is working ok)
hi im josh in cebu phils. may i help you? not open or no boot. If it doesn't boot or power on and no prsence of current on your pc. The main problem is motherboard. it may be no current is running on the board.because the supply chord was lost or not enough supply to make the motherboard execute.check if your power cable 16 pins is connected and the 4 pins 12 volts power support.if it loosen thats the problem. Sometimes the compatibility of your processor and the mainboard is needed.if both of these is for the first time check the compatibility of the mainboard and the processor in your support manual. good luck!
it happens when one of the component would not give the exact dc supply to its component near to each other and its so hard to replace a chips that has been broke down. okay, try this, although its to risky but theirs no other way to test your main board if its still good. if your video card is built in, plug the external video card. if your main board accept AGP or PCI then try them one step at a time. load the memory then try booting it again. if it still has no display bring it to a service center near you ask their assistance to make a series of test to your main board. Im sure they a device to test all the IC's and the chipsets. Good Luck!
