Question about PC Desktops

2 Answers

My computer is a Gateway(GT4023E). When I turn it on you hear the fan come on and the orange light for the disk drive. But the blue power light doesn't come on and the monitor is blank. Tested monitor on another tower (no problems). I put the tower up for months and decided to play around with it. It started right up. Now it is back to the original problem. Please help!

    Same GT4023E, was working fine for 1 year then does not boot up, monitor is blank but fans and disk run, but blue light does not come on. Tried replugging all device and peripherals but did not help. I actually got it to boot up once more since then, but then it went blank again. This looks like a Power Supply but I have not tried a new one.

    I have the same problem where the computer blue light does not come on although the fan is running. I called Gateway who said check the power supply or replace the motherboard. I read a solution provided on this website to pull powerplug off the motherboard and push in ram cards. I did this and unplugged the power supply. When I plugged everything back in it worked, until I turned off the computer again. The next time I had the problem, I just unplugged the power supply and plugged it back in. The fan came on by itself. I held down the button to shut off the computer, then pushed it on again. It came on and is working. I will check the voltage of the power supply. Otherwise, I expect the motherboard is going bad. I sure wish someone can give me a low cost, more permanent solution.

    There are actually two connectors on this board to the PSU, one is the 24 pin, and the other is a 4 pin connector labelled ATX 12V. Tried both but same problem.

I had this same issue late last year. Ended up replacing the mother board and system has been up and running ever since. I tried all the other ideas posted but none corrected the problem until I put in the new mother board.

This problem i have seen mostly with the d845gvad2 (series) motherboard. i myself is using it and it often happens. unplug the power supply connector from the SMPS and plug it again tightly, also press the RAM tightly, the RAM Sloth may be loose. Keep in mind, do it with the main power supply unplugged....

Black screen no cursor no keyboard use


When you powered on the machine did you hear any beeps, hear the fan running, the disk drive running, lights blinking, hear the cd drive click, see the light on the cd drive door for a second or two when it clicks? If these things are happening you are getting power. If not, your problem might be with your power supply, hard drive or motherboard. Remove the power cord, then press and hold the power button for 30 seconds, then plug it back in and press the power button. if it boots you had a static charge. If you get nothing at all but a silent system your power supply is bad. If it sounds like your computer is running but you can't see anything on the screen you might have a problem with your screen or video card. If you have another monitor try using it and see what happens. if it works so you can see things then your monitor was bad. If it does not work with another monitor but you still hear fans, and see lights and hear the disk drive spinning, then your video card is probably bad.

I turn on my tower and the fans move and the disk try clicks like it wants to spin then i turn the monitor on and it turns green them orange right away and says entering power save mode waht do i do


1) Unplug the computer from power.

2) Press the Power On button in, and hold it in for a count of 10 seconds.
(Count)

Let go of the Power On button.
Do this same procedure two more times. (Or until the Power On LED does not light up anymore)

3) Plug the computer into power. WAIT 1 minute, turn the computer on.

The fans should spin at high speed for a few seconds, then settle down.
Let's see if the computer boots.

Post back in a Comment, and we will go from there.

    Gateway computer does not turn on


    Without seeing the machine, I'm thinking you have a motherboard problem. But try these troubleshooting steps before throwing in the towell:
    Open the case and disconnect the CD cable. Now try it. If it still doesn't work, disconnect the hard drive and try it.
    Let me know what happens. I've seen CDs mess up a system like this. I many times will swap out the power supply, but I'm thinking with the lights flashing, its a more serious problem.

    Your cpu might have died. As the computer is starting tap F8 and choose last known good configuration to see if you can get it started.

    Won't boot. Power light on, No Video Signal message


    It's also possible that your operating system has become corrupted. See if there is enough time to boot into safe mode, or choose a boot option to go into the recovery partition.

    Have you made any recent hardware or software modifications?

    Orange Power light flashing


    Most likely a power supply failure. It apears that the power supply is not putting out all necessary voltages.
