Question about Gateway GM5084 PC Desktop

1 Answer

No screen at power on

I have a gateway gm5084 desk top unit. When powered on the light on the monitor goes from amber to blue like normal but nothing is displayed on the screen. I have removed all pci cards modem and wintv, I have removed all but one memory card I have removed the dvd cable all usb cables,tryed different hard drive cable locations, in otherwords I have skinnied down the unit and have eliminated anything that could be holding it down. I have measured the voltages and have 5.06 for 5 and 11.64 for 12. I put another video pci card in. The original is on the mother board. Its acting like the bios is not even coming up. Looking for ideas.. Thanks

    I have the same problem. The only work around I have found is to turn the computer off by holding down the switch and turning it on again, repeat about 5-10 times and it finally boots the bios...sometimes. I have also switched out the video card, cd drive, hard drive, and memory cards to no avail. Haven't tried the cpu or motherboard yet. Also the computer has gotten really sluggish and won't wake up quickly from screensaver state.
    I ran a bunch of diagnostic tests and they all say the computer is performing just fine.

I was getting the blue screen for a few months, and now when I power my Gateway GM5084 the lights come on and I hear it running but nothing comes up on the monitor. It's like it's not connecting...


First I would try a different video card to see if your video card is faulty or not. If you still can't seem to get any picture it could be that the power supply on your computer is starting to fail and not providing enough power to the video card.

Usually your PC will beep if it is a video card issue so if you don't hear beeps I would guess the power supply is the culprit. A replacement power supply is not that expensive and is quite easy to install as well.

Monitor appears to be in permanent standby mode - - black screen and blinking blue power light. It is a Gateway FPD2185W monitor. It will not turn off or on. Unplugging and re-plugging changes nothing. ...


Look for bad caps with bulging top in the power supply. I would replace all 10 with PANASONIC FM or FC series from DIGIKEY. Post back what you see inside so we can guide you further, see example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

The on off button on front doesn?t turn the unit off and on


Same here, your light went out if you put a VERY bright light on you'll be able to see something on the screen if you plug it up to your computer, if you are getting a new one go dell its worth it becase they last and are durable.

No display on screen and solid amber light on pcs' power button


it seems to be an issue with the power supply as you already tried replacing the motherboard
power supply will be less expensive do try to get it replaced first

do check that monitor iss fine
unplug the blue VGA cable which connects your monitor to the tower
if a 4 colored box moves all over the screen the monitor is fine
and if it doesn't
get the monitor either repaired or get it replaced.
