How do I know if the power supply is bad on gateway gt5676 computer? I push power button and nothing happens. I unplug it and the green light flashes on the power supply( Bestec ATX 300 12 EB3). Plug it...


u can buy power supply testers, just a device you plug the power supply into, or try a new power supply. but if nothing is happening no fans etc theres a good chance its just the power supply.

My computer will not turn on


many, not all, psu's will internally tripo after this happens. how to reset:
1 if it has an on/off button turn off for 1 min and turn on.
2 if it has no button but has a 110/220 switch, unplug it then switch to 220 then back to 110 (also this may be 115/230 or even 120/240)
3 if it has neither of these, unplug it for 10 mins, then replug it and start up.
also when you opened the case did you smell anything funny? if so i would say that the mobo and/or cpu are done for. i doubt this tho because you had them on a surge, but it is possible.
1 more thing when you opened the case did you by chance knock a wire loose from the mobo?(motherboard)
after re reading your post i question whether the surge strip is good, because you said it was tripped and yet you had the posu light on. or did you mean a light inside the case of the computer itself?
if none of these suggestions help you please re post with answers to the questions i asked thanx and hope i have helped.

My gateway desktop PRB 510S, if I turn it off and unplug it or electricity goes off, the computer wont start back again. Wont do anything. No lights no fan, nothing. Then 5 to 10 minutes after I turn it on...


Try connecting a different power supply to it. If the same situation repeats, then it's an internal (motherboard) problem. If the problems go away, then the power supply needs to be replaced.

6 years... I'm surprised the PSU even lasted that long! The power supply is the cheapest part of the PC and usually one of the first parts to fail. Don't worry, a replacement power supply is not too expensive. Good luck!

I push the on button and nothing happens. is it


Hello,

Even though a lot of things might have gone wrong and caused this, especially if where you place the System is not well ventilated, and the CPU becomes very hot, it shuts down automatically...and you will have to wait for a few moments, get a cool environment and power it on. but I will also try and tell you some troubleshooting steps that you can try.

Since you have already checked the power source and all is Ok, then try this out:

Disconnect your PowerPack(Power Supply Unit) from the CPU and try to power your PC with another Power Pack (Power Supply Unit), that you are very sure is working.

If it powers up, then just get a new Power Pack(Power Supply Unit) for system.

If you cant do this yourself, just get a good technician to do it for you.

Try this first and let me know how it goes, so as to know the next step.

Hope this helps.
Goodluck!

Gateway yellow power button, nothing starts, no fan, nothing. opened up computer and see mobo led light is lit. newton ps has a test button. tried to test with various components plugged in and the test...


Power supply has several voltages. Just because the 5v power is active doesn't mean all the voltages are OK. You need to have the power supply tested for 12v and 3.3v. A quick test is to unplug all the wires from the power supply. There is a single green wire on the motherboard main plug. Connect (use a bent paper clip) that green switch wire and any black wire. Plug in the power supply and it should run (fan starts)

I have a T3626 emachine that I replaced the drive.


check all your ground screws on the motherboard. If that doesn't work try booting it up with out the hard drive. if that doesn't work, pop out the BIOS battery and unplug your computer, let it sit for about a min. and put the battery back in and restart.

Hipro HP-d3057f3r computer power supply broken?


I have the same problem. I found this:

http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=us&docname=bph06788&product=12455#bph06788_section_2

  • Replace the side panel, plug in the power cord, and examine the light on the back of the power supply:
  • If the LED is on solid and is not flashing, the power supply is probably good and the problem is most likely caused by a defective component (processor, memory, PCI card) or a defective motherboard. Have the computer serviced, or remove the components and replace them, one at a time, to find and replace the defective component.

    Computer worked fine, unhooked it to hook up a new one, decided to hook the emachine back up to play games on, got it hooked up but it won't come on now. everything is hooked up right, i opened it up and...


    make sure you hook everything with a little force especially the memory until it snaps back into place. same goes for all the cards. care should be give to the cpu, nice and easy. make sure your power supply is potential enough or has not gone bad. The MB can give a green light but there could be too little energy for the whole system.

    Computer will not turn on


    Best way to check is to open your case. Near the power supply plug to the motherboard should be a little led light. If it is getting power to the board this light should be green. If it's unlit then most likely your power supply has gone bad. Hope this helps.
