Question about E-Machines T3985 PC Desktop

1 Answer

My PC won't power on.

One day my PC worked fine the next day I went to turn it on and it wouldn't turn on. I've tried different power cords and different outlets with no luck. When I plug the power cord into the back of the tower I hear a buzzing noise even if the power cord isn't plugged into an outlet. I'm not sure what to do.

First, check all connections insid the computer. then,depending on your skill level and warranty status, you can try the following:
Remove or disconnect all accessories from the pc (Hard drive, floppy, cd/dvd roms and accessory cards) Then see if it will turn on. If yes, the replace the items one by one unrtil it fails.
If no, then you must either try a different (known good) power supply on your motherboard. (you can also see if your power supply powers a known good motherboard).
If not, the you motherboard is likey faulty.

Installed a new graphic cards for Gateway DX4710-UB801A, it works for a day, but the next day, it wouldn't turn on, the power supply is not running.


Pull the new graphics card out to see if the power supply will start up, if no change, you will need a new power supply module.

We had a thunder storm a few days ago and that we lost power and that the pc shut down by it self so the next day we try to turn on the pc so it won't turn on please can you help us


Make sure that all the plugs are plugged in. Try a different outlet, if it's plugged into a surge protector make sure that it didn't trip. Or if is plugged into a regular power strip press the reset button on the side of the strip. If that doesn't work there usually is a fuse inside the PC that might have blown.

Dell Inspiron 531 (desktop) won?t turn on/boot


You've either got a bad motherboard or a bad processor (I'd lean to the motherboard being bad). I would honestly take this into a computer repair shop and have them check both.

Two months old dead no power


Hi there,

Check the Power cable of your PC for any damaged or burn/cut. Firmly check the connection on the slot of the CPU Power Supply,

Check the Electrical outlet , or better plug the cord on a different electrical outlet.

If all of this has nothing to do and the problem was still there, possible problem on the powersupply are, it is advisable that you have to replace this part, a possible burnt or a short circuit has happen inside, due to some electrical malfunction on your area.

HOpe this helps.

Let me know for any clarification

How old is your computer? Did you recently have a power outage or anything? Most the time if a computer won't turn on, something in it went bad OR an outlet is bad. Try this:

1. Make sure that the power switch is on, the switch in the back (on the power supply itself) is turned on, and everything along those lines is functioning.
2. If that doesn't work, and it will not power on AT ALL, make sure the cords are plugged firmly in place, including the surge protector and/or the power cord itself.
3. Try resetting the surge suppressor and/or plug the computer into a different outlet in the surge suppressor. Try other items in that surge suppressor (or even in the wall outlet, if that's what you're plugged into) to make sure that the outlet itself is working.
4. If your computer is plugged directly into a working wall or surge suppressor outlet, try a different power cord.
5. If your surge suppressor works, your wall outlet has power to it, and you are using a known-good power cord in the computer, you will have to go into more in-depth investigation as something inside the computer likely went bad. It could be the video card, motherboard, CPU fan, power button, or the power supply itself. Start by testing the video card and the power supply by (one at a time) swapping out a known-good component for the one you suspect may be bad. If it won't turn on after that, try swapping out the next and try it again. If it still will not work, it could be something more serious such as the motherboard or power button.

Good luck!

it could be a bad power supply or a bad motherboard. Other problems might cause issues, such as a bad video card.
