Power problem? Lights on mother board light up, fans start up when turn on, have to push reset button to get hard drive to spin up, cd burner wont open, mouse flashes on and off, and windows starts to open for a bit then blank screen saying no signal. Had ps tested at best buy and they said it is good. Hmmmmmmmmmmmm...

REWIRE THE ELECTRIC WIIRES.SHOULD THAT NOT HELP TRY WITH A OTHER PSU.

Will need the tender hands of a qualified repair person.

Does your laptop even begin the boot process where it displays stuff on the screen? Do you hear fans running, disk drives running, see lights, hear the cd drive click once and notice a light that comes on the cd drive door briefly when you press the power button? If not you computer either has a bad power cord, a bad dc power jack where the power cord plugs in, a bad mother board or static build up. 1) lets eliminate static buildup by removing the power cord and the battery then press and hold the power button for 30 seconds. Then replace the power cord but not the battery and hit the power button. If it boots up you had static build up. 2) Take an ink pen and put in in the slot where the power cord plugs into the laptop, if it wiggles loosely then your dc power jack which is soldered onto the motherboard needs to be replaced. 3) If the power jack is tight and when you plug in the power cord if you don't see any lights or hear a fan, disc, cd drive, then you can almost bet your power cord is bad. 4) If the power cord is ok then you have a mother board issue. Normally motherboards will give some beeps or constantly blinking lights when you plug in the power cord and try to boot up. These beeps or blinking lights will tell the technician what is wrong with your computer.

Try swapping out the ram 1 at a time, making sure there is one memory piece there while testing. If no! check hard drive for activity.

there is problem with u'r SMPS. repare it or change a new one

NO but ur power supply is going out

Is there a power switch on the back of the power supply which is not on? Make sure the power cord is good and plugged into a good power source. Do the fans run inside the system? Is the fan for the power supply working? If not the power supply could be bad. You can purchase a power supply tester to plug the mother board connector into to verify the operation for about $15.00. Do you see any lights on the mother board and the Hard Drive light flickering? If you do and your Key Board lights are on your video controller or monitor could be setup wrong or defective. If the power supply tests good then you need to test the memory and CPU. You could also carefully remove all boards except the video card, mother board and memory and see if it boots up.

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.

I understand that your cpu is not turning on and the repairer confirmed that it is the issue with the mother board. I suggest you to please check the smps fan spinning or not. If its spinning then then the issue could be with the mother board. If not try changing the power cables.

Next check whether your cd rom light is glowing. Even if there is an issue with the mother board, as the power is supplied by the smps the light  should glow if the light is not glowing its clear that something must be wrong with smps.

Please provide us the result of the above steps so that I could assist you further.

Hi, Did you just add the second CD? If you did you may need the driver for the mother board? Make sure the power cord for the cd has voltage plug it into the DVD drive also check the cable make sure red stripe is on the correct side of drive. You can download the driver at http://www.emachines.com/support/product_support.html?cat=Desktops&subcat=T-Series&model=T2672 User guide is there as well. The start button has a pair of wires with a small pin connector on it. This will connect to the motherboard if there is a 3 pin set you might try moving to the other pin. The new power supply also has to provide a start voltage? Your power supply may not be compatible or it may put the voltage on the third pin.
