POWER ISSUES? OR MOTHER BOARD......

I TURN THE POWER ON AND ONLY THE FANS RUN. I NOTICE SOME SCORCHING ON THE SMALL ( WHITE ) 4 PRONG PLUG MARKED( P2 ) WHERE THE 2 YELLOW / 2 BLACK, WIRES FROM THE POWER SUPPLY PLUG INTO THE MOTHER BOARD. SOMETIMES IT BOOTS UP, ONLY TO FREEZE UP ABOUT 20 MI. TO AN HOUR LATER. I KNOW THERE IS POWER BECAUSE OF THE SMALL GREEN LED ON THE MOTHER BOARD... SO MY QUESTION IS WHATS THE ISSUE? TO HOT? A SHORT? COULD REALLY USE SOME HELP HERE.. THANKS.

IT WAS THE POWER SUPPLY. AS SOON AS I PUT A NEW UNIT IN, IT BOOTED RIGHT UP... NO PROBLEMS YET AND IT'S BEEN ABOUT 20 HOURS. I WAS TOLD THAT A POWER UNIT WILL DO THAT BEFORE IT GOES FOR GOOD(ALONG WITH *********** BOARD)....

My desktop computer loses power when I plug the 4 prong power connector into the motherboard. I have tried a new power supply but it does the same thing


Maybe we need more information. The motherboard needs that connector. Is it disconnecting physically? Check the plastic clasp that hold it in place. Be sure the large ATX connector is connected properly. Unplug then plug it back in.
What do you mean by it loses power? Are the fans running when it is plugged in? Do the fans run when it is not plugged in? Try unplugging everything except your video card, CPU, RAM, and keyboard. Plug the ATX connectors in including the 4 prong one. If it still doesn't work check your capacitors. They are the cylinder looking cans soldered on the motherboard. Are they bulging or leaking? Might be time for a new motherboard. Good luck.

Don't know where to attch all plugs for gt4016 mb


what plugs? All of them? Power supply plugs should be marked as well as different. Hard drive cable gos in the # 1 slot dvd and so on go in slot #2. If the cpu fan is installed some have a power supply plug others plug in to the mother board. Most of the time it will be close to the cpu and only a two prong plug. Most of the time all the of the wires will be marked in small writing on the plug itself and its as simple as getting a flash light and match the plug with the socket on the board that are almost always marked

I have novice computer experience when it comes to internal repair, but i was working on a E-machine T6211 and after cleaning out all the dust, it turns on, the fans run, no led lights come on, the cd rom...


OK, it sounds to me like you have one of two issues going on.

When you clean out dust near the mother board or system board you need to be VERY careful. There are small diodes that stick up from the system board that are very sensitive. So, if they get hit or the small wires that connect them to the board get severed, you system board could get damaged.

From your description, you are getting power to the system board, but there are not signals going from the system board to any of the drives. Inside your computer, there are several ribbon cables plugged into the system board. Make sure that all the cables are plugged in securely at both ends. Also, there is on large collection of wires coming from the power supply that go to a large, white rectangular plug that plugs into the system board. Make sure that this is securely plugged in. There may be another small white square plug that also plugs into the system board and provides power.

If all the cables are secure, check the power cables as well as the ribbon cables, and your hard drive and CD drives are not responding, I would guess that you have a damaged system board.

Do this with the computer powered off and unplugged.

Please check this and see if it makes any difference.

Let me know.

My e-machine will not turn on....I have put in a new power source, tried a different turn on switch, the power light on the mother board comes on but its as if it is just plain dead...no fans run when youi...


My sister had the same issue with hers. She said one day it died. I replaced the power supply, the little lights on the mobo came on, but the computer did not power up. Come to find out, when the "best-tec" power supply fried, it surged the motherboard and fried that as well. I replaced the motherboard and it works like a charm.

The purple light is flashing in the front and tries to start and won't turn on. disconnected power cord and held button in for thirty seconds still have same issue what could it be?


This can be a faulty power supply or a damaged mother board. here's how you can confirm.

When pressing the power button, inspect the cooling fan that is located on the back of the power unit where the power cord plugs in. if the fan starts then stops immediately, this will confirm a damaged power supply.

Now, if the fan continues to operate but, the CPU doesn't start to power up and load the OS, thsi will confirm a mother board issue. replace the mother board in this case.

Yellow light on dell dimension 2400 and it won't work


HI, this is signaling an issue that is concerning the power unit(power supply). this can also be an issue with the mother board as well. you can confirm the actual issue by, inspecting the cooling fan that is on the power unit. if the power unit fan is not running when you push the power button to power up the PC, replace the power supply. if the fan is running, replace the mother board.

No start up , button lites up - cd-rom wont open , noticed no fans on for 3d card or big one on mother board


If the cpu/heatsink fan isn't turning then most pc's will shut down to avoid further damage to cpu & board. I would first replace the fan if it's the one over your cpu. Try replacing power supply. If your board has the 4 pin plug, you must have that plugged in. But keep in mind if that fan isn't running a new power supply isn't going to make it start working. You have to have that fan working. Then go from there. If once it is working & other devices like video and/or roms aren't, check your memory. The best way to troubleshoot devices are to plug one at a time in and power up until the problem starts. Hopefully you won't have to go to that step.
