Question about Gateway GT5622 PC Desktop

1 Answer

Computer doesn't work with monitors, yet turns on properly (Not a monitor problem)

I want to say I had this computer for at least a decade and I haven't used it since last year but the monitor didn't seem to show anything. Yet, it did work this one time for a brief moment. Maybe it's because I haven't used this computer in a long time. I wanted to make it work today by changing the power supply. It wasn't that nor the monitor. It's either the component or the motherboard. But everything seems to work just fine as usual, blue light on power button is functional (not blinking), normal fan sound. I tried two working monitors and it brings up a blank screen or a glitched screen. What is its problem?

The usual problem with a completely blank screen, even with known working monitors is the graphics card. Relatively easy to put right with a new graphics card unless the graphics is built into the motherboard. This can be checked by looking on the back of the computer. Is the video outlet grouped with the keyboard, mouse etc sockets or separate from these. If it is with these the graphics card is built into the motherboard and would be uneconomic to do anything with unless the board takes a separate card. If you want to try a separate or different graphics card, make sure you get the correct interface, PCI, AGP, PCIe etc etc

SOURCE: Fan is running, power button with blue light is off, cpu won't boot up

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.

SOURCE: 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.

This is Nvidia's dreaded video chip cold solder joint problem. I have fixed many of these in my shop. Two choices, get it fixed or buy a new motherboard.

No power at all


If your monitor doesn't turn on, and you are sure of the power supply (some plug directly into the wall and some use a power adapter), then you can assume that the monitor has failed.
You can fix it (replace the power supply in the monitor itself or possibly the on/off switch), have it fixed by someone who knows how to do this, or buy a new monitor.
First, of course, be sure the problem is your monitor and not the computer. If the monitor light turns green and then yellow, you can assume it's the computer. If the monitor light doesn't go on at all, it's the monitor.

My computer's tower turns on but it doesn't display on the monitor, the monitor shows the normal Self test box so the monitor doesn't seem to be the problem. Also when I press the power off...


Make sure that the cable is connected from your computer to the monitor, and if it is wiggle it and push it in all the way. If it has screws, screw them in. If that does not work, check that your monitor is on the correct input (if it has multiple) then see if anything comes on the monitor. If nothing happens you should buy a new cable from the store. If all of those steps do not work your computer or your monitor might have a more serious problem.

My acer monitor p191w will turn on acer logo comes on goes black then a screen comes out saying no signal then turns of light turns yellow ...tried restarting monitor nothing


Connect the monitor to a different computer, to see if the monitor works at all.

Connect a different monitor to your computer, to see if your computer really is "sending" a video-signal through the "data" cable. If not, then either the data-cable or the video-card inside the computer is faulty.

TFT185W80PS monitor is not working


Check if your monitor power led indicator is on if it is, try to check the cables of your monitor if it is properly plugged to your CPU if it isn't plugged it properly if the problem still doesn't solve try to open your cpu and and uninstall your video card if you have a separate one and clean it with a pencil eraser then install it again and try it if it will work. But if your video card is built in, there is a problem with your video card or maybe your monitor try to contact a reliable computer technician..Hope it will help you.

Tells me I'm in a power saver mode. Screen is blank. Model is 2241V


That message comes up when the monitor doesn't get a signal from computer, and enters power save mode until computer comes on. This usually means that the computer's not starting up when you turn the power on. It may also mean that some problem has occurred with the computer's video circuitry.

Begin by checking that the computer is actually starting up properly. Look for the normal startup signs (lights on the computer showing power and disk access, fans running, sounds through the speakers). If you're sure that the computer is working and getting into Windows, try another monitor. This will tell you if the monitor is bad or if there's a video issue with the computer.

Self-Test Feature Check (STFC) Your monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. If your monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:
  1. Turn off both your computer and the monitor.
  2. Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove Analog (blue connector) cables from the back of computer.
  3. Turn on the monitor. The floating 'Dell - self-test Feature Check' dialog box should appear on-screen (against a black background) if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains green and the self-test pattern will scroll through the screen continually.
  4. Turn off your monitor and reconnect the video cable; then turn on both your computer and the monitor.
If your monitor screen remains blank after you use the previous procedure, check your video controller and computer system; your monitor is functioning properly.

Thanks
