Question about EliteGroup K8M800-M2 Motherboard

1 Answer

Replacing a power supply.

My PC failed to boot, the power led had lit. I held in the on/off switch for the appropiate time for it to shut down the PC. I switched on again and the 5 amp fuse in the power lead plug blew. There was a burning smell which I think came from the Power Supply Unit. I have changed the power supply but the replacement does nothing, I have checked the unit by shorting out the power on pins and the PSU fan comes on.
What my query is................is that the old PSU is a 20 pin ATX and the replacement is a 20/24 Pin ATX. Am I correct in assuming that I can just leave the extra 4 pins (these are on a small additional connector alongside the 20 Pin Connector) hanging and that the pin outs on the 20/24 way connector are compatable with the 20 way connector. Many thanks, Jim

    Thanks for your suggestion.....in fact there is an additional 4 pin 12 volt connector that plugs into the motherboard, I have this in. Having found a pin out list for both the 20 pin and 24 pin connector it would seem that I can just leave the extra 4 pins hanging. I think, as you have suggested, that the fault is on the mother board and that the Power S/W is not activating the PSU. I have shorted out the pins on the PSU and it does work out of the PC.

    I am now going to investigate the Motherboard.



    Thanks again,



    Jim

Hi,

You need to connect both 20-pin and 4-pin connector to *********** board. Your 4-pin connector is located between your CPU and a I/O connectors.

If you did it right first time, check if you have anything shorted on your board because your old P/S could go bad for reason.

Good luck!!!

How to fix a motherboard that does not turn on at all.


Make sure there is power at the outlet, surge suppressor, power strip. Be sure any connected UPS is on. Try again.

Remove any recently installed hardware and go for boot. If the PC boots, check to make sure that the new hardware does not overload the old power supply - if it does, replace with a higher capacity power supply and go for boot.

Open the PC. Look for indication of power - LEDs, fan, etc. Replace the power cord between the outlet and computer if one is available, and go for boot.

If possible, obtain a power supply tester to determine if the power supply has failed. Replace any failed Power Supply and go for boot.

Disconnect power. Disconnect all non-required cables and accessories. Leave only the power and data cables for power supply, boot drive, video card, mouse, memory and keyboard connected - everything else should be removed (with the exception of the small cables that go to the MoBo headers for LEDs, and switches on the case). Everything means both data and power cables. All controller cards should be removed as well unless using on-board or built-in controllers. Reconnect power and try for Boot.

Add devices, cables, etc one at a time to determine which is causing the fault. A PC that boots and shuts down shortly after could be an indication of overheating / over load. Clean dirt & dust from case, ventilation slots, etc. Make sure all fans spin freely - replace any that do not.

Those are some things to start working on.. hopefully, you'll find the problem and not have to go further. Good luck!

Normal shut down on pc, now it will not power up.


if you can figure out what pins your power switch is plugged into you can try and bypass the switch as for the power supply itself i know theres a way to trick it and boot just the power supply but i cant remember what pins on the plug it is try and google the power plug layout it should tell you what pins to connect to boot it

This is typical of a failed power supply. Look on the back of the power supply, there may be a red switch for input voltage. Unplug the power cord, flip that switch a few times and then plug the cable in and try again. If nothing changes, see if there's a small black button on the back of the power supply. If there is, unplug the power cable and press the button and hold it for 10-15 seconds. If an LED flashes or turns on, then plug the cable back in and try again. If this all fails, replace the power supply.

EMachine T2482 Computer won't power on or boot up.


Try removing the power cable from the power supply. Wait 10 seconds, and replace it again. Try powering up the computer. If it doesn't power up, check that the motherboard has power (there should be a LED on the board which is lit up. Of course, check the fuse also in the plug.

If the LED is on, you have a failed motherboard / Switch. If the LED is off, then you have a failed power supply. Beware though, if the PSU has blown, it could easily have taken the motherboard with it.

Presario 2200 Notebook won't power up


try disconnect power then remove battery,plug power back in and try to boot.if nothing happens put battery back in and see if it charges.if it does leave to charge for a while,try to boot if it dont boot you know its neither the power or battery and shouldnt cost too much to repair(probably a capacitor dead , possibly transistor blown diodes only allow electricity to travel in one dirrection so only break if shock(drop or bang hard) resisters have about a 100yr life.

Power LED on but no boot up


it could be your power switch, veriy that it isnt the power supply by

1.) un-plug it from the main board
2.) look at the main board connector(one coming of the power supply)
3.) you should see green wire and next to it a black one
4.) using a paper clip bridge the too wires
5.) if it works proceed to net step if not get a new power supply

to check case switch and board switch

1.) plug in power supply to main board
2.) look at the pins where the power button connects to
3.) using a metal object (blade screw driver) bridge the pins

if the board should start up>
then its your power button on the case that is bad, you can try to repair it, chage it or buy a new case,

if it doesnt work.
1.) ensure that jcms(jumper to flash the bios) is set correctly
2.) unjack each drive one at a time to see if any is causing stalling
3.) get a new main board
