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.

Emachines t3958 wont power on


The green light means there is standby power to the motherboard.
Power button may be broken, does it 'click'?
With the case open, do any of the fans start, then stop?
If yes to the above, you may have a bad power supply. Can you borrow one to try?
Last test before it's the chip or mother board:
Remove the connectors for power from drives, video card, all but the motherboard (Do NOT disconnect small connectors on the motherboard, just POWER from the drives and video card)
Remove any expansion cards except video. Note where they go.
Try again. If it starts and fans run ok (video may not work but fans go normally.), shut it off, reconnect the video card. Try again, power off, connect or install one thing at a time until it stops running again. The last item plugged in is the culprit.
Always one item, power on, try it, then power off, try the next one.

No power,power supply seems ok,green light on mother board on. when pluged in the fan runs for a couple seconds and turns off.power button has no effect.


sounds like a mother board issue,

start with pulling out all ram chips and re try,,

then try pulling all cards out like old modem and also cdroms.

if ever thing but power is unpluged its a bad mother board or CPU chip

Power problem?


My thought would be motherboard if the PSU has been tested. Prime candidate would be the capacitors.

If you take a look at the caps on the board, if any of them are bulging and/or leaking then we have a winner. Caps can be replaced but you do need some skill with a soldering iron!

HP Compaq Presario SR2013WM ...Power Problems ?


Unless the power button sticks or does not pop back out, i doubt the issue is in the switch, but it can be tested by replacing it with a momentary switch from Radio Shack (not an exact fit, but good for testing)
This sounds like a power supply issue. That would be the first thing to check. If it is NOT connected to anything except the power cord , it shouldn't run unless switched on.
Could also be the motherboard, but before you start dismantling the computer , check the obvious. Open the case (usually to screws on the back) inspect all the cables, reseat your ram chips and addin cards.
Not to scare you ar anything, some of these presarios have bad capacitors on the mother board. coupled with the fact that they are difficult to clean (inside) and airflow is not maximized in the case, they tend to cause the capacitors to swell and leak, losing voltage.
When you are inspecting the insides of your case, take note of any capacitors (little cans with crosses on the top) on the main board inside around the CPU fan that are swollen or leaking.
If you find these in bad condition , i would replace the motherboard.

Amber light on power button


Check to see if there are any loose connections to the memory cards on the memory board. Make sure the data cable to the drives are connected properly. Is the fan in the power supply on?

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.
